Why is it that Arab states that don't like Syria and some of its actions want others to resolve the problem? See "Arab League Endorses International Action", David D. Kirkpatrick, New York Times, 2013-09-01?
Saudi Arabia and Egypt are far stronger militarily than Syria. Could it be that they don't want to be seen as Arab against Arab? Turkey is also stronger militarily than Syria.

The U.S. has provided billions of dollars in military sales or aid to several military powers in the Middle East, including "the latest air-to-air missiles and precision-guided air-to-ground missiles" - "U.S. Militarization of the Middle East", Seema Luthra, Fellowship of Reconcilation.
