My belief is that you have to let these civil wars settle themselves. Whoever wins the war, the US will immediately send aid and representatives. Just because some idealists feel that the US should go in and tilt the war in favor of the rebels because they are supposedly non-terrorists is crazy. Look at the mess there is now with Libya and Iraq. In Egypt the Muslim Brotherhood was stopped by the army and they have a semblance of peace. These jihadists will not stop.
It is interesting to look at what war monger McCain would have done already in Syria with bombing strikes. Thank God he didn't become president.
