Moving Space Force HQ From Colorado To Alabama Is Stupid

Trump is about to renew his efforts to move the headquarters of the Space Force, a fifth military service that he created, from Colorado (where the headquarters of the part of the Air Force bureaucracy that was transferred to the separate Space Force service was located before he created the Space Force), to Alabama. He tried to do so during his first term, but the moved got bogged down in Department of Defense red tape, and the Department of Defense reversed that decision during the Biden Administration. 

UPDATE:

President Trump said one of the main considerations for moving Space Command out of Colorado Springs is because Colorado voters largely vote by mail. 
“I will say I want to thank Colorado,” Trump said. “The problem I have with Colorado… they do mail-in voting, they went to all mail-in voting, so they have automatically crooked elections." 
Trump has long criticized voting by mail, and has cited the practice as a major reason he lost the 2020 election to Biden though he has not provided evidence of fraud emanating from mail-in ballots." . . . 
The Denver Metro Chamber of Commerce estimates that Space Command supports nearly 1,400 jobs and has a $1 billion impact on the Colorado Springs economy. Colorado has a significant Space Force presence, hosting half the bases with its major operations, including Peterson as well as Schriever Space Force Base in the Colorado Springs area and Buckley Space Force Base in Aurora. Nationally, the branch has more than 14,000 military and civilian members, who are called Guardians. 

Colorado Attorney General Phil Weiser on Tuesday said his office was prepared to challenge in court Trump’s decision to move the command, though he did not elaborate the legal rationale for a lawsuit. . . . 
Huntsville, nicknamed Rocket City, has long been home to Redstone and NASA’s Marshall Space Flight Center. The Army’s Space and Missile Defense Command is also located in Huntsville, which drew its nickname because of its role in building the first rockets for the U.S. space program.

This is almost certainly not a legitimate reason for executive branch action under the Administrative Procedure Act. It is also an outrageously false claim.

Colorado Pols has more details.

END UPDATE

This is very on brand for Trump. He is making a call that places partisan politics above what is best for national security and wastes federal dollars.

Alabama is less attractive than Colorado to the civilian employees and contractors (who have a choice unlike active duty service members), so it won't attract the same quality work force. And, if one was going to move it away from Colorado one could have justified an HQ in Florida or Texas, which are also GOP strongholds, but like Colorado and Washington State, actually have a space industry (but see the material in the update above about Huntsville). Charitably, the best that can be said for it is that it provides economic development assistance to an underdeveloped part of the U.S.A. that supports him politically. Less charitably, it can be seen as a political payoff to Senator Tommy Tuberville who was getting in the way of Trump's Defense Department agenda. Less charitably still, it is a way for Trump to try to take action solely attributable to him that will become part of a military service's legacy once the bad decisions that went into that choice are long forgotten.

Tearing down old infrastructure to move it somewhere else is also just wasteful, while providing no benefits to national security. It is will probably require a billion or so dollars of unnecessary defense spending.

Of course, creating the "Space Force" was a bone headed idea in the first place. It undermines interservice cooperation, and honestly, it would have been better to be truly conservative and roll the Air Force back into the Army, rather than further dividing the Air Force. There might be a time when a Space Force makes sense, but that time is far in future.

Space Force's military role remains ill-defined and it remains a work in progress that is currently creating more confusion rather than a stronger U.S. military. Do we really need a new Space Force academy? Do we really need Space Force reserves? How is it doing anything that the Air Force did better? How many people are even in the Space Force? According to Google AI it apparently has 9,400 active duty "guardians" and about 4,600 civilians, making it far smaller than even the Coast Guard.

Trump's other wasteful symbolic military acts

Trump's other symbolic military initiatives are similarly dubious. His military birthday parade in the District of Columbia on June 14, that the Army aptly converted to a boring historical display from the third-world dictatorship show of force that he wanted in an act of malicious compliance, it was a wasteful and expensive flop.

The idea he has floated to change the name of the Department of Defense to the Department of War (as it was called during and before World War II), were also wastes of money, but at least are basically harmless. Indeed, the calling it the Department of War is also more honest.

Trump's intent to reassign Confederate names to U.S. military bases is fundamentally endorsing treason and insurrection and is patently un-American.

Trump's inappropriate domestic uses of the military

Trump's deployment of military force, mostly but not entirely, national guard troops, on the other hand, in addition to being a waste of money, are grossly improper, manufactured crises that threaten democracy, undermine federalism, are inappropriate for immigration enforcement, and are illegal.

The Courts rejected his efforts to criminalize illegal immigration by calling a large swath of the border a military base, and have rejected his characterization of illegal immigration as an "invasion" of the United States for constitutional purposes. Courts have also held that deportation flights he had the military make in violation of court orders were illegal.

Courts have shut down his military deployments to Los Angeles. As the New York Times explains:
A federal judge in California said President Trump broke the law by deploying roughly 5,000 Marines and National Guard troops to Los Angeles in June in response to immigration protests. The judge said on Tuesday that Mr. Trump, Defense Secretary Pete Hegseth and the Defense Department had violated the Posse Comitatus Act, which generally prohibits using the military to enforce domestic law. The judge barred them from using the troops for any law-enforcement purpose, but put the order on hold for 10 days. The administration is expected to appeal. . . . 
The ruling was the latest in a series of judicial battles over claims of expansive unilateral powers by the administration. Mr. Trump and administration officials have deported people without due process, imposed widespread and unpopular tariffs and rolled back energy regulations, citing wartime and emergency powers that have been disputed in federal court. 
The president also declared crime in Washington, D.C., to be an emergency in order to send federal troops there in August, although crime rates in the nation’s capital have actually been falling and local officials said the deployment was not needed. Since then, Mr. Trump has publicly mused about sending the National Guard into other Democratic-led cities. Federal law gives the White House more latitude to conduct local law enforcement in the District of Columbia than in the states. . . .
The ruling places strict limits on the what the troops can do and applies only in California, although the judge noted that Mr. Trump and Mr. Hegseth “have stated their intention” to use Guard troops as a “national police force with the president as its chief.” Gov. Gavin Newsom of California praised the decision, saying Mr. Trump’s efforts were “illegal, authoritarian, and must be stopped in every courtroom across this country.”

Other bad defense department decisions.

These aren't the only bad defense department decisions he's made. He's banned books at the military academies (eventually rescinding all but a few of those bans). 

He wiped all mention of women and minorities who contributed to the U.S. military on government websites (another decision he has mostly backed down from in the face of court action and bad P.R.). 

He's systemically fired or removed from command women and minorities whom he has called "DEI hires" while putting in place less qualified individuals chosen for political loyalty. 

He's baselessly fired transgender troops contrary to their civil rights and denied them their legitimate benefits for being laid off and having served with distinction.

He's purged the ranks of generals and admirals and national intelligence officials to replace them with political loyalists. Trump's major appointments in the defense and national intelligence sectors have involved woefully unqualified people who have made major public blunders.

His openly revenge oriented revocations of security clearances and security details for various officials has been disgraceful.

The mixed bag of Trump's military deployments and threats abroad.

Trump's deployment of U.S. forces have been a mixed bag at best.

Trump wasn't wrong to continue Biden's policy of militarily engaging the Iranian backed Houthi rebels in Yemen who have been using advanced anti-ship missiles from Iran to interrupt maritime commerce in acts of piracy that they claim are in support of Gaza but really have nothing to do with it. But then, he just lost interest and ended U.S. involvement.

Trump wasn't wrong to provide some extra military support to Israel's raids on Iran to thwart its nuclear capabilities, although the B-2 bomber strikes he made were less effective than might have been hoped. And, of course, this is a problem of his own making created when he pulled the U.S. out of President Obama's deal with Iran to end its nuclear weapons program.

Trump, in his first term, set up Biden for failure, and the Afghan government installed by the U.S. and its allies for collapse, by negotiating with the Taliban for a U.S. withdrawal that left the Afghan government out of the loop and left Biden holding the bag when he took office, just a month or so before the scheduled pull out date. And, in his second term, Trump has broken faith with Afghan citizens who served U.S. forces in Afghanistan at great risk to their own lives by trying to revoke the immigration protections that the Biden Administration and his own administration in his first term provided to them.

Trump has been indecisive, has wrecked our alliances, has taken absurd and counterfactual positions, and has played into Russia's hand with respect to the Ukraine War, even though with immense bipartisan political pressure from Congress and from the Defense Department, he hasn't entirely abandoned it.

Trump's utter abandonment of Africa, ending U.S. Aid in a way that has killed hundreds of thousands of people and will kill millions, planning to close all U.S. embassies there, and imposing tariffs upon it, has basically ceded the entire continent to China.

Trump has been less firm than he might have been in the Philippines-China clashes in the South China Sea caused by Chinese Coast Guard harassment of Filipino military and civilian shipping in places that international law has declared to be international waters.

Trump's response to the situation in Israel with Gaza has ranged from rudderless to absurd with his call to vacate Gaza and turn it into a Trump owned beach resort. By floating the proposal without even consulting his advisors, he has undermined U.S. credibility on the issue.

Trump's deployment of naval forces towards Venezuela seems to be an attempt to manufacture a war. His early threats to invade Greenland and Panama and Mexico, contrary to the sovereignty of a NATO member, to treaty obligations, and to international law, and to annex Canada, have likewise been toddler level moves that have undermined U.S. credibility in foreign affairs and turned us into a global menace.

The mixed bag of Trump's procurement decisions

Trump's military procurement decisions have also been a mixed bag.

The cancelation of the M10 Booker light tank (that the Army refused to call a tank) was a good move. Cancelling the Joint Light Tactical Vehicle for the Army (one of the best procurement decisions that the Army and Marine Corps have made for ages), while keeping the Army's buy of the obviously bad Infantry Squad Vehicle that ignores all of the lessons the Army learned in Iraq and Afghanistan was a very bad move.

Cancelling the Army's successor to the M113 was mostly a good move, but leaves the Army without a next generation medical transport and field hospital vehicle, even though other parts of that buy were unwise. Progress on an Osprey-like tilt wing successor to the Blackhawk helicopter in the Army is positive. Upgrading Army small arms makes sense.

The decision to boost purchases of the B-21 Raider and the F-47 Air Force fighter (to replace the F-35A) aren't horrible decisions, nor is the decision to continue the Collaborative Combat Aircraft (a.k.a. Loyal Wingman drone) program. Looking at ways to use cargo aircraft as bombers or missile launching platforms also makes sense. This administration's continued failure to recognize the need to have a close air support aircraft (shared with past administrations), however, even if the A-10 is just too old, wasn't wise. Trump's absurd attempt to play aerospace engineer and claim that the F-47 really needs twin engines, however, is more toddler level governance.

A focus on improving U.S. air defenses in a program known as the Golden Dome (playing on Israel's Iron Dome), on ramping up U.S. drone production, and on rushing to get drone defense resources fielded aren't wrong. Developing hypersonic missiles also makes sense. 

Developing new anti-ship tactical nuclear missiles, however, is a bad call and doesn't meet a real military need since existing anti-ship missiles are more than adequate to sink any ship in existence.

The decision to fund development of Elon Musk's SpaceX Rocket Cargo program which is technologically challenging, doesn't have a proven track record of quality control, and doesn't meet an urgent need, is less wise. This contract is just political payback.

It is honestly still hard to tell, more than seven months into the administration, what it's naval policy is. The Navy is appropriately looking at a major increase in unmanned ships and submarines, and at containerized anti-ship missiles for ships that wouldn't ordinarily have any missiles. Is the successor to the F-35C on or off? Is the Constellation class frigate on or off? Where is the Littoral Combat Ship program? Do we really need more old model Arleigh Burke destroyers? Does spending big bucks on maintaining a large scale amphibious attack capability really make sense?

Trump has talked big about using the U.S. military against cartels in Latin America, but the Department of Defense has apparently done nothing to prepare for this historically law enforcement and Coast Guard mission.

Context For The Latest Episode Of The Cambodia-Thailand Conflict

Not so long ago, international wars were viewed as a thing of the past, after a long lull at the end of the 20th century (with the brief, but notable exception of the Gulf War in 1992, which was prompted by Iraq's invasion of Kuwait), leaving only insurgencies and cross-border fights with military forces not sponsored by recognized sovereign countries. 

But, the 21st century has proved that this lull was only temporary. We've seen the Russia-Ukraine War (in 2014 and 2022 to the present), there have been military clashes as recently as this year between India and Pakistan, Israel and the U.S. have attacked Iran (which has also struck Israel), the U.S. and Saudi Arabia have recently engage the Houthi regime that is the de facto ruler of Southern Yemen after it attacked merchant ships off its coast, and there have been low intensity naval clashes between China and the Philippines in the past couple of years. A six day war between Cambodia and Thailand this month has added to that roster.

The latest round in a 118 year old border dispute related to a historic Hindu temple built by the Khmer Empire during what were the Middle Ages in Europe, near the current border between Cambodia and Thailand, led to a six day military conflict between the two countries that left at least 38 people dead and displaced at least 310,000 people, until a cease fire took hold yesterday. The two nations have had military clashes for hundreds of years, even before the ambiguous 1907 map that is at the root of this particular border dispute took hold. 
Shots were heard early on Thursday morning near Prasat Ta Muen Thom, an ancient temple on the disputed border between the two countries. Senior commanders from the Thai and Cambodian militaries agreed to de-escalate one of the bloodiest border conflicts between their nations in decades on Tuesday.The deal seemed to end, at least for now, [six] days of fighting that killed at least 38 people. More than 180,000 people in Thailand have evacuated from areas along the border, while in Cambodia, more than 130,000 people have fled their homes.

Each nation accused the other of firing first.

The Thai Army said on July 24 that Cambodia had fired rockets into civilian areas in four Thai provinces, prompting Thailand to send F-16 fighter jets to strike targets in Cambodia.

Cambodian officials said that Thai soldiers had opened fire on Cambodian troops first, at a temple claimed by both nations, called Prasat Ta Moan Thom by the Cambodians and Prasat Ta Muen Thom by the Thais. They said Cambodian forces returned fire some 15 minutes later.

The ownership of Prasat Ta Muen Thom / Prasat Ta Moan Thom is disputed by the two countries. Cambodia’s de facto leader, Hun Sen, claimed in a social media post that a Thai military commander had “started this war” by ordering the closure of the temple on Wednesday, and opening fire on Cambodian troops the next day. Thailand has accused Cambodia of starting the conflict.

The temple is in disputed territory, and people there speak Khmer, the official language of Cambodia, as well as Thai — highlighting the cultural overlap. The area is known for ruins from the Khmer Empire, which lasted from the ninth to the 15th century.

Arguments about where the border should be, and who owns the temples in the region, have led to decades of disputes. In 1962, the International Court of Justice awarded Cambodia sovereignty over the Preah Vihear Temple (known as Phra Viharn in Thailand), another temple about 95 miles away. In 2013, the court, the top judicial body of the United Nations, tried to clarify the 1962 decision. It said that Cambodia had sovereignty over the immediate area around that temple, but it left unresolved who controlled a larger disputed area. The border disputes can be traced to a 1907 map created during French colonial rule in Cambodia. The two countries interpret the map differently. Military fighting has broken out intermittently since 2008, but the last time that a major clash turned deadly was in 2011.

The two countries have had occasional military clashes and nationalist rivalries for hundreds of years.

The quoted material above (and below) is all from today's New York Times, but I have reordered the quoted material to be more readable, in this particularly poorly structured and edited article (which also includes duplicated sentences), and as a result, have not specifically noted where I omitted parts of the story. 

The cease fire was negotiated by Malaysian diplomats, with input from the U.S. and China.

The U.S. does not have particularly strong ties to either party in the conflict and wasn't directly involved in it, even though it claims to have participated in the peace negotiations, so news coverage of the conflict was relatively modest. But, the U.S. has historically favored Thailand, a constitutional monarchy which was one of the few countries never to fall to colonial powers, since it generally speaking sided with the West in the Cold War, over Cambodia, with its history of one of the most violent communist revolutions in history, which China has tended to favor.

An equally interesting aspect of the latest conflict is that Thailand's prime minister was suspended from office by a Thai court for controversial statements made not long before the shooting broke out, which is a political tactic that would be unavailable in most countries (but might be desirable if the grounds for it were suitably defined), in which the status of the prime minister would be primarily an issue for the parliament. Also, relatively few countries recognize the intermediate sanction of suspending a head of government without actually removing the head of government from office.
The border tensions have already contributed to a political crisis in Thailand: On July 1, a Thai court suspended the prime minister, Paetongtarn Shinawatra, because of comments she made about the dispute.

In June, Ms. Paetongtarn spoke by phone to Hun Sen, who is . . . Mr. Hun Manet’s father [Hun Manet has been the prime minister of Cambodia since 2023], to discuss the escalating border tensions. Mr. Hun Sen has had close ties to [Ms. Paetongtarn's] father, Thaksin Shinawatra, a former prime minister of Thailand and the leader of a powerful political dynasty, as well as one of the country’s richest men.

Mr. Hun Sen posted a recording of their call, in which Ms. Paetongtarn seemed to disparage Thailand’s powerful military and take a deferential tone. She called Mr. Hun Sen “uncle” and told him that she would “arrange” anything he wanted.

In response, thousands of protesters took to the streets of Bangkok to express their outrage. Although Ms. Paetongtarn apologized, she has faced pressure to resign.

The Imperfect Case That The Army Is Too Light

An argument that the Army is too light gets some points right, but others deeply wrong. 

How can we have forgotten the terrible lessons of the early 2000s, when losses in Iraq and Afghanistan prompted a scramble to deploy up-armored HMMWVs and Mine Resistant Armor Protected Vehicles? Today’s Army, far lighter than the one that took such damage in so-called “low-intensity combat,” is ill-equipped to deter or contend with the likes of China or Russia.

Let’s take roll of the Army’s 31 active maneuver brigades. Eleven are heavy brigades equipped with tanks and infantry fighting vehicles—well-protected platforms suited to modern war.

Another six brigades are Stryker formations equipped with their eponymous lightly armored, wheeled infantry carriers. Originally called the “interim armored vehicle,” the Stryker was intended to serve only until the arrival of the Future Combat Systems, which imploded instead. From conception, Stryker units have suffered from doctrinal and conceptual confusion. Stryker units carry more dismounted troops than Bradley units, which are intended to fight primarily mounted. But they are infantry carriers, not infantry fighting vehicles. With poor off-road mobility, they are vulnerable to hand-held anti-armor systems, and their units have towed rather than self-propelled artillery. Repeated National Training Center rotations show they cannot survive when employed against armor.

The remaining 14 active maneuver brigades are light infantry formations, cheaper and easier to deploy but, realistically, unable to compete with today’s threat. Under current guidance, they go to war in “infantry squad vehicles”—essentially, unarmored dune buggies without heavy weapons.

Compounding the problem, the commanders of these light brigades have dramatically less firepower than they used to. The recent decision to eliminate the air cavalry squadron from the aviation brigade in Army divisions removes half of each division’s 48 AH-64E attack helicopters, a massive reduction in combat power. Only slightly less dangerous was the Army’s recent decision to deactivate the cavalry squadron in Stryker and light infantry brigades, with their many wheeled vehicles and heavy weapons. The same directive stripped light infantry battalions of their antiarmor/heavy weapons companies: mounted formations armed with automatic grenade launchers, heavy machine guns and heavy antitank systems. These actions removed much of the brigade’s available firepower.

Meanwhile, light artillery battalions still use the venerable M119 105mm towed howitzer, which has a lower rate of fire, shorter range, and weaker weapons effects than the 122mm and 152mm systems used by Russian and Chinese brigades. They are also slower to displace than self-propelled systems, making them far more vulnerable to counter-battery fire and drone attacks.

Promises to offset all these reductions with “Unmanned Systems and Ground/Air launched effects” raise serious questions, given the lack of specifics provided and DoD’s poor acquisition track record.

A quick look at adversary force structure illuminates the challenge. Russian maneuver brigades (tank, motor rifle, airborne/air assault, naval infantry) are remarkably similar. All include four maneuver battalions; three artillery battalions (both tubed and rocket); anti-tank, air defense and reconnaissance battalions; and an electronic warfare company. Chinese brigades have four maneuver battalions supported by strong artillery, air defense and EW units. U.S. brigades have three maneuver battalions, a single artillery battalion, and no dedicated anti-tank, air defense, or EW units. At higher echelons, adversary artillery, air defense and EW continues to outmatch U.S. capabilities, and both the Russian and Chinese militaries have evinced strong commitments to advance their drones and unmanned systems. Overall, their forces are clearly stronger, a dilemma only exacerbated by repeated moves to lighten or weaken U.S. ground forces.

What should the U.S. Army do? Several things: re-equip light brigades with protected, wheeled transport mounting heavy weapons, as before; restore their antiarmor companies; increase the density of Javelin anti-tank and Stinger air defense systems across light formations; replace towed light artillery with wheeled, 155mm systems like the French Caesar or German RCH-155; reverse the deactivation of divisional air cavalry squadrons; and arm divisional UH-60 assault helos with the Hellfire antitank missile system.

Stryker brigades should be converted into true heavy brigades, perhaps with reconditioned M1 Abrams tanks and M2 Bradley fighting vehicles that are now in storage. Hundreds of earlier variants of the M1, M2, and M109 self-propelled howitzer are stored at Sierra Army Depot in Nevada. Should Stryker brigades be retained, they should include an armor battalion, similar to Russian motor rifle brigades. Heavy brigades should be upgraded with the M1A3 Main Battle Tank and M2A4 Infantry Fighting Vehicle as soon as possible.

Army divisions should field a general support 155mm artillery battalion in addition to the artillery battalions providing direct support to the maneuver brigades. All brigades and divisions should include air defense and electronic warfare units, as well as dedicated drone formations with trained operators at every echelon from company to division.

America has not fought a high-intensity war against heavy forces since the Gulf War, when it enjoyed crushing superiority in all domains. Today that superiority now longer exists.

Touted as a move away from a GWOT-focused Army to one more focused on “lethality” and better suited to the Indo-Pacific region, current changes in fact cut deeply into the Army’s ability to hit hard and mass combat power. An America optimized to fight in only one theater is an America content to be a regional but not a global power—a recipe for decline. In the real world, challenges erupt suddenly and unexpectedly (think December 1941, June 1950, October 1963, August 1990 and September 2001). True national security requires a flexible and adaptive Army trained and equipped for sustained, intense combat at the high end of the spectrum of conflict. This means mobility, protection and firepower in all Army formations.

In a word, light is not lethal. It’s time for a rethink.

From Defense One.

What does this analysis get right?

Sufficient armor to protect troops against small arms fire and IEDs does make sense. The “infantry squad vehicles”—essentially, unarmored dune buggies without heavy weapons, indeed don't make sense. They utterly unprotected against even rain or hail or dust or snow or children throwing rocks. They have no weapons of their own and don't have storage capacity to carry squad scale heavy weapons or medical supplies. And, they concentrate a whole squad in a tiny space where a single grenade or volley of automatic weapons fire or IED can kill all of them in one blow. It isn't particularly capable off-road (unlike, for example, the Humvee). The only thing that recommends an infantry squad vehicle at all is that it is faster than walking. Using that as the core model for 14 of 31 Army Brigades is indeed nuts. Maybe one or two brigades of them for paratrooper type deployments into very lightly armed theaters might make sense, but these are, indeed, far too light for almost any conceivable conflict. 

These units aren't even really heavy enough to take on civilian drug cartels (as President Trump has urged the Army to make a priority). U.S. police SWAT teams routinely use more armor and heavier weapons to take on tiny domestic drug dealing gangs in U.S. cities, and protesters without firearms, or a single violent boyfriend and husband or mass shooter with a handful of small arms none of which is more than 0.45 caliber.

Cutting close air support from helicopters with missiles doesn't make much sense either.

But, how can you think that the future of near peer ground warfare lies with heavy tracked tanks and infantry fighting vehicles after having seen how the Ukraine War has played out. The author of this piece forgets that the U.S. Army deliberate fielded few main battle tanks in Kosovo due to its mountains, and that it took many critical weeks to ship them by boat and train to the front in all of the conflicts in which the U.S. has been involved since the Gulf War, despite the fact that the pace of modern warfare has not gotten slower.

Strykers and MRAPs were adequate in the main U.S. wars since the 2000s, the firepower of the main M1 Abrams tank has not been very useful, tank v. tank warfare is basically no longer a thing, and guided missiles like anti-tank Javelin missiles, Hellfire missiles, and TOW missiles have all delivered much more firepower per pound, with greater precision, at equivalent or longer ranges than the main guns of tanks. Traditional tanks like the existing Abrams and traditional infantry fighting vehicles like the Bradley, have no air defenses and no anti-drone weapons, are challenging to operate in tight urban warfare and mountain warfare settings, and aren't particularly mine resistant.

Another lesson of the wars that the U.S. has fought in the last 25 years is that off-road capabilities, where tracked vehicles are a bit faster than off-road capable wheeled vehicles, are rarely used in practice. But the tracks vehicles slow down their entire units, and because they are profoundly less fuel efficient, require more, completely vulnerable fuel tanker trucks to be sent to supply them (and those tanker trucks can't go to the off-road places that the tracked vehicles can). In wars where the front lines are often ill-defined, this is a huge problem.

As for howitzers, either towed or self-propelled, tracked or wheeled, there are also problems. Their range is only 12-24 miles. They are very heavy relative to their firepower. And, they aren't very accurate, so its takes multiple rounds to destroy a target. Mortar systems are even worse in basically every respect. Guided missile systems like HIMARs, or like or Hellfire and Javelin and TOW missiles, produce equal or greater results, with much more accuracy, at longer ranges which enemy artillery can't reach.

We need a middle ground. Yes, Army units should have heavy and lethal weapons like grenade launchers/canons, heavy machine guns, anti-tank missiles, and anti-aircraft missiles. But, for just about anything more than 50mm rounds, guided missiles or handheld recoilless rifles (e.g. for breaching bunkers or fortifications) are superior to tank shells and artillery shells.

Also, yes, they should mostly have sufficient armor to protect against shrapnel and small arms fire, and provide force protection to resist land mines and IEDs. But trying to use heavy armor to protect military vehicles against dedicated anti-armor weapons is generally futile. In Ukraine, every single type of armored tank or infantry fighting vehicle, former Soviet and Western alike, has taken extremely heavy losses no matter how strong their armor was. Against these threats, the options are to either run and hide so as not to get hit, or to employ active defenses like Israel's Trophy system, or lasers, or ground based versions of the Navy's Phalanx close in weapons system, or electronic warfare tools that disrupt the guidance systems of cruise missiles and drones.

And, finally, except in extremely niche roles in very small numbers, wheeled vehicles are superior to tracked vehicles. They are lighter. They can still handle many off-road condition. They are much faster. And, they are much more fuel efficient.

A new off the shelf JTLV, which weighs about half of the original M2 Bradley (which means that you can deploy them in twice the numbers in the same time and with C-130 aircraft that can't transport a Bradley), has about the same fire power as the Bradley, and is similarly or more protective against forces without anti-armor weapons. Both are equally vulnerable to forces with anti-armor weapons. And, the JTLV is 50% faster and has a much lighter logistics trail (it needs much less fuel per mile than a tank or a tracked infantry fighting vehicle) and is cheaper. Yes, it carries fewer infantry to dismount, but this is made up for by allowing units to field twice as many of them.

Looking at how Strykers perform against armor is a straw man argument. Strykers aren't meant to primarily be tank destroyers, any more than it makes sense to send masses of dismounted infantry up against a machine gun nest for no cover. Their carried soldiers need anti-armor weapons (like the Javelin missile, or TOW missiles) that have a range longer than the range of a tank, or other systems to support them, like helicopters or drones armed with anti-tank weapons need to be deployed as tank destroyers.

Current U.S. military doctrine is based upon the assumption that U.S. forces will quickly gain air superiority, and will then use that air superiority to destroy enemy armor and artillery, before U.S. ground forces move in. Strykers aren't supposed to enter the field of battle until the armor, that they indeed don't fare well against head to head, are dispatched, and especially not a close range without at least anti-tank weapons for their dismounted infantry.

The Ukraine War, Houthi attacks on shipping, and recent clashes between Israel and Iran, however, have demonstrated that gaining air superiority and dominance may not be possible in every case, particularly against longer range guided missiles and one way armed drones. Traditional anti-aircraft weapons, meanwhile, are optimized against manned helicopters and fixed wing attack aircraft, not numerous cheap, deadline guided munitions that blur the line between armed drones and guided missiles. Against a "near peer" force, slow and heavy main battle tanks and infantry fighting vehicles, with big, vulnerable logistics trains are targets and not assets.

The U.S. Army does need to increase air defenses and drone defenses across the force. And, the U.S. military should seriously consider switching out more vulnerable and slower attack helicopters as close air support providers, for more robust and faster dedicated close air support aircraft to replace the A-10, and drones, in addition to traditional fighter aircraft designed primarily for air to air combat, and bomber aircraft, at high altitudes, dropping "smart" bombs.

The U.S. Marine Corps has learned these lessons. It has ditched its tanks and howitzers, but kept integrated fixed wing fighter aircraft and armed helicopters to support them. 

The U.S. Army hasn't yet fully woken up to these realities and is still trying to fight World War II and the Korean War.

The Foreseeable Conflicts

It also bears noting that wars against China and Russia, which the author identified as the threats against which the U.S. Army needs to be prepared, are two very different things. 

Plausible Russian Scenarios

The Ukraine War has given us a sneak preview of what a war in Europe with Russia would look like. The Ukraine War also means that Russia's resources to fight a large scale conventional war will have been profoundly reduced. And, any plausible conflict with Russia would be fought not by the U.S. alone, but with all of its European NATO allies. 

Tanks have been destroyed at high rates by both sides in that conflict and their main guns have been very unimportant in that fight. 

Conventional howitzers received heavy use early on, because that is what was available to Russia and Ukraine at first. But now, 70%-80% of the damage is done with armed drones, missiles, snipers, and machine guns do a fair amount of the rest of the damage, and while artillery does still play a significant role in that conflict (because the supply of drones and guided missiles is more limited) it is steadily decreasing as artillery batteries are destroyed (the Russian's have lost more than two-thirds of their's so far and lose more almost every day), while supplies of drones are being replenished (since replacing lost howitzers is much more difficult). Further, artillery resources have not given either side enough of an edge to budget the current territorial front lines for years. 

And, if the U.S. and NATO, unlike Ukraine, were able to overwhelm and defeat Russian air defenses (which their guided munitions, satellite intelligence, stealth aircraft, and medium range artillery missiles would all help facilitate), Russia would be in a much worse position in terms of conventional warfare. Still, one might try to argue despite this for heavier U.S. Army forces.

Plausible Chinese Scenarios Don't Heavily Implicate The Army

In contrast, there is no sensible scenario in which U.S. forces invade any significant part of mainland China with a plan to hold it and rule it for any significant length of time.

The U.S. missions in the Indo-Pacific theater, vis-a-vis China, are to (1) protect Taiwan from being invaded, (2) protect the Philippines from maritime harassment or subjection by China, (3) to protect Hawaii, Alaska, and the U.S. territories in the Pacific (e.g. Guam and the Northern Mariana Islands) from invasion or embargoes, and (4) to protect Japan and South Korea and other allies in the region from Chinese attacks or intimidation.

A threatened invasion of Taiwan is the dominant concern among those possibilities. And, mostly, the U.S. role would to be employ the U.S. Air Force, the U.S. naval aviation, U.S. surface combatants with anti-ship missiles, U.S. attack submarines, and naval and air force resources from Japan, South Korea, and Australia, and possibly other U.S. and Taiwanese allies, to sink as many invading Chinese ships and destroy as many Chinese aircraft as possible, in support of Taiwanese forces on the ground, and to destroy the facilities on the coast of China from which those forces are deployed without occupying them on a medium or long term basis. 

The U.S. Marine Corps, based in places like Okinawa and Guam would play the leading role in reinforcing Taiwanese ground troops on the island of Formosa and nearby islands. In part, this is because the U.S. Army with the help of U.S. Air Force  and allied transport planes going into a contested airspace, and painfully slow U.S. Navy transport ships going into a contested maritime space, wouldn't be able to arrive in meaningful numbers in sufficient time to make a difference (especially their heavier forces which would have to come from South Korea, Hawaii, Alaska, and the West Coast of the mainland U.S.). 

And, invading Chinese forces that did manage to make it to Taiwan, would most likely be light infantry, because all or almost all of the ferries carrying heavy Chinese armor would likely be sunk by a barrage of air, sea, and land sources missiles, torpedos, and sea mines while crossing the 100 mile straight to Formosa from the Chinese mainland. U.S. special forces or Marines might briefly set foot on the Chinese mainland to destroy an airport or a port or a military base or to disrupt the supply chain of the Chinese forces, but they would most likely bug out as soon as their narrow and destructive mission was accomplished.

Taiwanese forces would be doing the heavy lifting to fight any Chinese forces that managed to cross the straight and in dealing with inbound Chinese missiles and armed drone with whatever anti-drone and anti-missile defenses they could muster. In any conflict where U.S. Army ground troops were doing more than just tipping the balance slightly in an evenly matched fight between invading PLA troops and Taiwanese defenders, their role would be a lost cause, and would need to happen in a matter of days, before PLA victory became a fait accompli. Artillery or tank duels between the U.S. Army and the PLA are highly unlikely.

All of which is to say that the Army's case that its forces need to be heavy armored forces to engage in a ground war with China doesn't stand up to close scrutiny. Even if the Army is able to secure the long range fires with a 1,000 mile range that it is seeking in defense procurement fights, that wouldn't matter. Hawaii is about 5,250 miles away from Taiwan. Alaska and the U.S. mainland are farther away. 

South Korea is about 830 miles away from Taiwan (about 28 hours or more by U.S. Navy transport ships once at sea through highly contested waters) and this distance would put it barely within striking distance with missiles with ranges almost three times as great as its current longest range option (which is in short supply). This is also too far for the Army to deliver its troops by helicopter without midair refueling in the face of very vigorous Chinese air defenses.

Okinawa, which has mostly Marines and Air Force and Navy personnel, is 400 miles away from Taiwan (which is still 13 hours away on an amphibious assault ship through hotly contested waters). Guam is about 2,750 miles from mainland China and has naval and air bases, but no meaningful Army or Marine Corps presence.

There are no U.S. military based on Taiwan itself, so it has almost no prepositioned troops or heavy military equipment there, and it doesn't have the depth of a relationship with local military forces that it does in Japan and South Korea either.

Plausible Scenarios Against North Korea

Really, the only plausible scenario in which U.S. Army forces would be engaged in ground combat with heavy opposing forces in Asia would be in North Korea, defending South Korea together with its own forces and with support from Japan and from other branches of the U.S. military. This would be a profoundly different kind of conflict than the conflicts against China or Russia that the author references.

North Korea may be armed to the hilt, but it is still a small country and its forces are hollow. And, it would be facing adversaries who had been planning for this moment for decades.

The Second Division of the U.S. Army, which is the main U.S. combat force stationed in South Korea (in addition to about 8,000 airmen), is divided between an artillery brigade with armored, tracked M270 multiple rocket launchers, and a combat aviation brigade with a mix of Apache AH-64 gunships, an assault regiment of troops deployed in UH-60 Blackhawk helicopters, and a regiment of general support transport helicopters, as well as some larger reconnaissance and armed drones.

The Seventh Air Force stationed in South Korea consists of two fighter wings with three squadrons of F-16 fighter aircraft and one squadron of A-10 attack aircraft.


There are about 300 sailors at a U.S. naval base in Busan, which is about 4,860 miles from Hawaii (about 162 hours by naval transport ship, in addition to time to travel from Busan to the DMZ over land). So, it would take more than a week to get more U.S. Army soldiers and equipment to South Korea that could not be air lifted (although the Marines in Okinawa would be much closer, about 25 hours by ship to Busan plus addition time to the front over land).


There are about 100 Marines and about 100 special operations forces and 20 Space Force "guardians" at the Army base there (Camp Humphreys) that also houses the 20,000 U.S. Army soldiers who are not special forces, and the U.S. Air Force base with 8,000 airmen.
Camp Humphreys is 40 miles (64 km) south of the former base in Seoul and about 60 miles (97 km) from the Demilitarized Zone that divides North and South Korea. That puts the base about twice as far from North Korea as its predecessor, one of the main reasons for the move. While the new location moves the bulk of U.S. troops out of the range of North Korean artillery, the North Korean military has developed large caliber rockets and ballistic missiles, as well as a nuclear capability, capable of reaching Camp Humphreys.

Camp Humphreys is 143 miles from Busan Naval Base, which is less than three hours away for wheeled vehicles (or by train) and less than four hours away for tracked vehicles by road. It would take another hour to the DMZ for wheeled vehicles and another hour and twenty minutes for tracked vehicles by road. So, it would be a full seven days of travel from Hawaii to the front by sea, assuming that no detours were necessary to avoid attacks in contested maritime waters, and however long it took to load and unload the forces onto their sealift, to make sealift arrangements, and to decide to deploy them. 

The Marines from Okinawa make take a couple of day to arrive by sea with heavy equipment and reach the front.

The B-2 Is Rarely Used

Despite the small size of the U.S. B-2 bomber fleet, it isn't a heavily used resource despite its immense cost.

The U.S. bombing yesterday of five bunkers where Houthi rebels in Yemen stored weapons (which killed no civilians) was carried out by a B-2 bomber.

The last time that this class of bomber was used in combat before this week was seven years ago in 2017 in a January 18 strike on an ISIS training camp by two B-2s. 

Before that it was used to strike targets in Libya in March of 2011. 

They were used 49 times in the wars in Afghanistan and Iraq in 2003. 

It was first used in combat in the Kosovo War in 1999 (where it was used heavily), two years after it entered military service in 1997. The first B-2 bomber flew thirty-five years ago on July 17, 1989, eight years before it entered military service.

The B-2's global range (6,900 miles, which can be greatly extended with aerial refueling), stealth capabilities, and heavy bomb payload (20-25 tons) is a combination unmatched in the world. It has a crew of two. 

Just 21 were built (driving up the per unit cost immensely) and 17 remain in service, while four had accidents or crashes that removed them from service. This is quite unimpressive for such a small number of aircraft when the number of combat missions it has flown in the 27 years it has been in military service is so small. 

The U.S. is in the process of fielding a replacement B-21 bomber which is quite similar in design and capabilities to the B-2.

Stray Thoughts

* The U.S. does a horrible job of using contraflow (i.e. having major highway have some lanes run in the opposite direction to accommodate the needs of people evacuating) when it is appropriate for things like people evacuating from Hurricane Milton in Florida. It also greatly underuses this tool to manage day to day shifts in the direction of traffic in and out of central cities with commuters. This should be standard operating procedure in both cases and would not be expensive. It could save hundreds of lives a year and get people where they needed to be much faster with existing infrastructure.

* Similarly, the National Guard underinvests in resources for evacuating people from natural disasters and places with civil unrest, despite the fact that this is one of its core missions. Amphibious all terrain buses with light armor sufficient to deal with debris and distant civilian small arms fire, for example, is an asset almost every National Guard could use.

* Search and rescue drones for the National Guard (e.g. small ones like the one in the link that can go into small spaces that may be unsafe) should also receive more funding.

* Self-righting boats are cool. They are mostly used as lifeboats. Being on a cruise ship in the direct path of a Category 5 Hurricane on the other hand, is terrifying.

* There is a $4000 device that prevents people from dying while they are trapped in a flood of grain in grain elevators. It should be much more widely used.

* Poor training and tactics for responding to people with mental health crises or who are suicidal, who don't have firearms, is one of the biggest unnecessary source of deaths caused by police. Colorado Springs police officers provided us with an example of this just after midnight this morning.

* For a lot of reasons, I favor abolishing municipal courts in Colorado. Some abuses in Pueblo illustrate the problem.

* The U.S. economy is extremely healthy. Crime is down dramatically to the lowest levels since 1969. We are not at war for the first time in more than twenty years. The fundamentals couldn't be better. This should not be a close election.

* Denver Ballot Issue 309 is probably a constitutional taking as it would shut down the sole slaughter house in Denver, potentially exposing the City and County of Denver to hundreds of millions of dollars of inverse condemnation liability.

* The U.K. has conceded it is not sovereign over Diego Garcia, while retaining its military base there.

* The U.S. Navy recently rescued some civilian Iranian mariners who were in distress.
the brand-new destroyer received a fresh tasking: deter aggression and protect “the free flow of commerce” in the waters of the Middle East. While there, the crew heard an emergency call. “A distressed mariner is a distressed mariner,” Cmdr. Kevin Dore, the commander of the Inouye, said Friday after his ship and crew tied up at their homeport here. “If an emergency like that happens, it is ‘Get there as fast as you can and do everything you can’ to save what, in this case, was two distressed mariners who happened to be Iranian.” The crew sent search-and-rescue swimmers out in a small boat, rescued the mariners, and gave them medical assistance.

* Quality pre-school is more beneficial to a child when the child's peers in later grades also went to quality pre-schools. When the child's peers in later grades didn't receive the same quality pre-school, the benefits of quality pre-schooling "fade out."

* Wars involving Israel are ongoing a year after October 7, 2023. It is simultaneously fighting in Gaza against Hamas, against the Houthis of Yemen, against Iranian missile strikes, and against Hezbollah in Lebanon. It's military is remarkably effective on all fronts and it is stopping something like 99% of inbound missiles and drones. It is fighting lower key fights against Hamas in the West Bank. Despite the devastation in Gaza, Hamas was still firing missiles at Israel this week.

* Russia has been clamping down on reproductive rights and now bans even talking about why someone might want to not have kids at all. 

* Seriously underwater mortgages are, surprisingly, most common in places that don't have particularly high housing prices.

* This could be true:


* Fewer high school and college students are also working than there were thirty years ago.


* A downtown Denver high rise office building recently sold for 80% less than it was purchased for. Vacancy rates in downtown high rise office buildings are at record highs in most major U.S. cities, mostly due to the rise of remote work that reached a tipping point during the pandemic.

More Thoughts On The Conflict In Israel

* Palestine hasn't been a sovereign state for more than 75 years and the international community has done great harm by supporting this expectation. Palestinian claims for a right of return have no validity. Claims that people who have never lived in Israel proper (which is the case for most Palestinians in Gaza) are refugees aren't valid either. Conquest is a legitimate basis for sovereignty.

* In the same way, the international community has done great harm by refusing to recognize the People's Republic of China's claim to Taiwan and by not pressuring Taiwan to drop its claims to the mainland. 

* The current conflict is fundamentally the fault of the Hamas leadership in Gaza supported by Iran.

* The military actions of Hezbollah, Hamas, the Houthis, Iranian backed militias in Iraq and Syria, and Iran, purported directed at Israel are all completely unjustified. The U.S. and Israel should formally declare war on all of them, exterminating completely all of the soldiers and political leaders behind all of Iran's proxies and destroying Iran's military capabilities and nuclear efforts of all kinds completely.

* Gaza claims that 32,000 lives of its 2.3 million people have been lost, it should count itself lucky that the number is so small. Everything that it has suffered, it has brought on itself, with broad popular support. It should have unconditionally surrendered. Instead, even now, most Gazans support the decision to launch the October 7 attack, and still is pushing for Palestinian sovereignty, and still wants to exterminate Israel. They tried, over and over again. They lost. It's over. The Middle East will be at war forever until the world acknowledges once and for all that the Palestinians lost.

* Gaza cannot support 2.3 million people anymore in any sustainable way due to destroyed homes and infrastructure. Something like half of the population needs to be relocated somewhere. And, about the same proportion of Gazans would like to leave. The international community should stop questioning the fact that most Gazans need to be relocated, i.e. exiled, basically permanently, and should start recruiting countries to receive exiled Gazans. Exile is really the only solution that is humane and viable. If the Islamic world really cares about the people suffering in Gaza, it should offer to take them in with open arms.

* Cease fires, efforts to reinstate local home rule, and so on, are only aggravating the suffering.

* The Palestinians of the West Bank should be given a choice: be ceded to Jordan or be exiled with the people of Gaza. They chose Hamas to lead their home rule too, and as such, they should not be eligible for further local home rule.

Hamas, The Houthis, Hezbollah, Iran, And ISIS-K

Hamas and the Houthis have provoked the responses that they predictably received with wide popular support for their actions.

The decision of Hamas to conduct the October 7, 2023 attack on Israel still had strong majority support among Gazans months after the attack when the devastating consequences of that decision were clear. 

Likewise, the Houthi attacks on shipping and U.S. warships in the Red Sea are a boost to Houthi political support and legitimacy in the parts of Southern Yemen which it controls that is home to 70% of the population of Yemen, despite the fact that the insurgency it has waged there has led to a catastrophic humanitarian disaster there.

Every bit of Israeli and Western military response in Gaza and against the Houthis was deliberately provoked and had broad popular support. In both places, large majorities actively wanted to inflict harm on the U.S. and to obliterate Israel entirely. And, Gaza also continues to keep 100 or so Israeli hostages and has done nothing to surrender.

So, in both cases, while there is clearly significant suffering and plenty of people in each place, like children did nothing to deserve it, neither population is very sympathetic. Each of them brought what they are experiencing upon themselves through deliberate provocation and evil conduct. 

Iran's Role

Of course, Iran is to blame too, for giving them firepower and intelligence that they otherwise would have lacked, and for egging them on behind the scenes. Iran has played a similar role in providing capabilities for and egging on Hezbollah which has waged war on Israel for Lebanon for decades, and Shiite Islamic militias in Iraq and Syria.

Iran's role in world affairs is complicated. 

The war in Yemen is a proxy war between Iran and Saudi Arabia to a great extent, yet the two countries recently reached a Chinese brokered peace accord. China is also looking to strengthen its ties to the Houthis as a way to exempt its own merchants from Houthi piracy. China has previously joined naval coalitions against Somalian pirates in the same region. On the other hand, China is lukewarm toward Russia since it can't alienate its Western trading partners too badly, and has pulled back a majority of of expatriates and economic investments in Africa in the last five years or so, after having spent years trying to build economic and political influence in Africa and across the second and third worlds.

Iran is a key military supplier and source of military technology for both Russia and North Korea as a result of the military industrial capabilities it was forced to develop for itself after decades of Western sanctions. It probably has a few nuclear weapons, has proven it has long range missile capabilities, and its naval might in the Persian Gulf is rivaled upon plausible U.S. naval adversaries only by Russia, China, and North Korea. Iran has also not refrained from using its military capabilities on occasion and has designs on making Shiite majority Iraq into one of its client states.

Yet, Iran reached a treaty, from which Trump promptly withdrew, with the U.S. during President Obama's administration. Its democracy, while flawed and subject to a theoretic veto, is more of a real democracy than most of the Middle East and West Asia. While Iran presented itself to the world as a Shiite theocracy, it actually have considerable religious diversity and is almost as far along the path towards secularism as places like the U.S. and Ireland in terms of grass roots belief, even though the waning religious conservatives have the upper hand in terms of political power. Iran would be a natural place for an Islamic analog to the modernizing Protestant Reformation in Europe to emerge under the right circumstances. Iran has oil wealth, but unlike many other reasonably developed Islamic countries, also has a substantial commercial and manufacturing sector, leaving it in circumstances that have more in common with Turkey and Egypt, than with Saudi Arabia and UAE and Brunei which are dominated by oil wealth, or Yemen and Afghanistan which have little more than subsistence farming interrupted by long periods of civil war.

Israel's Overkill

Israel's response in Gaza has probably been overkill although it is also completely understandable. Hamas and kindred Islamist movements in Gaza, the West Bank, and across the Middle East have been trying to exterminate Israel and to wipe Jews from the face of the Earth almost since its inception in 1948. When Israel gave Gaza more autonomy and withdrew from direct supervision of the region, the Palestinians put Hamas in charge and Israel got terrorist bombings, endless rocket attacks, and the October 7 massacre in return.

President Biden treads the difficult path of not adding aid and comfort to those who would destroy Israel, while simultaneously trying to mitigate humanitarian suffering in Gaza. And, contrary to the views of many on the left, Israel is not just an American puppet that is compelled to do the bidding of an American President in response to an existential threat to it and its people.

About ISIS-K

As an aside, the terrorist attacked recently carried out at a concert in Moscow that killed about 144 people and seriously injured at least 100 more was the work of four Tajik terrorists affiliated with ISIS-K. ISIS-K is one of the main opponents of the Taliban in Afghanistan, although they obviously have no problem with the idea of an Islamist theocracy. 

ISIS-K stands for Islamic State - Khorasan, a reference to the 7th and 8th century CE kingdom in what is now Islamic Central Asia that included "western Afghanistan, northeastern Iran, the eastern halves of Turkmenistan and Uzbekistan, western Tajikistan, and portions of Kyrgyzstan and Kazakhstan." The region was first united under the pre-Islamic Sasanian Persian empire, and then became part of the first two Sunni Islamic Caliphates:

First established in the 6th century as one of four administrative (military) divisions by the Sasanian Empire, the scope of the region has varied considerably during its nearly 1,500-year history. Initially, the Khorasan division of the Sasanian Empire covered the northeastern military gains of the empire. . . .With the rise of the Umayyad Caliphate, the designation was inherited and likewise stretched as far as their military gains in the east, starting off with the military installations at Nishapur and Merv, slowly expanding eastwards into Tokharistan and Sogdia. Under the Caliphs, Khorasan was the name of one of the three political zones under their dominion (the other two being Eraq-e Arab "Arabic Iraq" and Eraq-e Ajam "Non-Arabic Iraq or Persian Iraq"). Under the Umayyad and Abbasid caliphates, Khorasan was divided into four major sections or quarters (rub′), each section based on a single major city: Nishapur, Merv, Herat and Balkh.

The Abbasid Caliphate gots its start in Khorasan around 750 CE, was a high water mark of the Islamic empire in a golden age which lasted more than five centuries until 1258 CE, and persisted in some form for more than two and a half centuries after that, until the 1517 CE when the Ottoman Empire replaced them. The Ottomans, in turn, were the most powerful Islamic country in the world and expanded well into the Balkans, for centuries, but then faded in a long, slow decline, until it fell, roughly the end of World War I, when the current politics of the Middle East began when the colonial powers that won in World War I drew the boundaries of the modern Middle Eastern states and picked the rulers for those countries.

The Abbasid Caliphate or Abbasid Empire (/əˈbæsɪd/ or /ˈæbəsɪd/; Arabic: الْخِلَافَة الْعَبَّاسِيَّة, romanized: al-Khilāfa al-ʿAbbāsiyya) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH). The Abbasid Revolution had its origins and first successes in the easterly region of Khorasan, far from the bases of Umayyad power in Syria and Iraq. The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph Al-Mansur founded the city of Baghdad, near the ancient Babylonian capital city of Babylon and Persian city of Ctesiphon. Baghdad became the center of science, culture, and invention in what became known as the Golden Age of Islam. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it an international reputation as the "Centre of Learning".

The Abbasid period was marked by dependence on Persian bureaucrats (such as the Barmakid family) for governing the territories as well as an increasing inclusion of non-Arab Muslims in the ummah (Muslim community). Persian customs were broadly adopted by the ruling elite, and they began patronage of artists and scholars. Since much support for the Abbasids came from Persian converts, it was natural for the Abbasids to take over much of the Persian tradition of government. Despite this initial cooperation, the Abbasids of the late 8th century had alienated both non-Arab mawali (clients) and Persian bureaucrats.

The political power of the caliphs was limited with the rise of the Iranian Buyids and the Seljuq Turks, who captured Baghdad in 945 and 1055, respectively. Although Abbasid leadership over the vast Islamic empire was gradually reduced to a ceremonial religious function in much of the caliphate, the dynasty retained control of its Mesopotamian domain during the rule of Caliph al-Muqtafi and extended into Iran during the reign of Caliph al-Nasir. The Abbasids' age of cultural revival and fruition ended in 1258 with the sack of Baghdad by the Mongols under Hulagu Khan and the execution of al-Musta'sim. The Abbasid line of rulers, and Muslim culture in general, re-centred themselves in the Mamluk capital of Cairo in 1261. Though lacking in political power (with the brief exception of Caliph al-Musta'in of Cairo), the dynasty continued to claim religious authority until a few years after the Ottoman conquest of Egypt in 1517, with the last Abbasid caliph being Al-Mutawakkil III.

And, as an aside, who were the Sasanians? 

The Sasanian Empire or Sassanid Empire, also known as the Second Persian Empire or Neo-Persian Empire, was the last Iranian empire before the early Muslim conquests of the 7th to 8th centuries. Named after the House of Sasan, it endured for over four centuries, from 224 to 651, making it the second longest-lived Persian imperial dynasty after the Arsacids of the Parthian Empire.
