The United States Department of Defense has once again adopted lame New Speak designed to advance its political ends somehow. It is now trying to call the body of water commonly known as the Persian Gulf the "Arabian Gulf", apparently, CNN was the only significant traditional media co-conspirator. Of course, this bright idea is strictly a recent invention of the propoganda department and has never had currency as a "grass roots" useage, despite protests to the contrary from those charged with implementing the policy.
Then again, military useages sometimes become popular ones. For example, the term "Middle East" derives from British military and colonial office useage.
