Syrian Rebels have come out and said, that if they don't get more arms and aid from their backers, they are not going to go to Geneva for the talks being held later this summer. They are upset that Assad is getting arms from Iran and Russia, and that they are not receiving aid from the United States and Europe. The problem from America's point of view is that the rebel leadership is in disarray.
Last week the Assad troops captured the town of Qusair. Giving the rebels a black eye. With the ever changing situation bringing a new headline daily all this is going to accomplish is a regional war. Rebels wake up and fight and quit your whining.
