She wants both sides to stop being supported by Saudi Arabia/Iran; I can imagine how the congress could get SA to stop supporting the rebels, but do you think it will be that easy with Iran? It will just become a one side street with all the dictatorships in the region supporting Assad, and of course he'll win and re-run his oppressive system one more time. By the way, this conflict might give him excuses to go after his opponents among the civilians in even harsher ways, and a lot of people might suffer just for what they think. Is that what you'd want?
