Just to be clear, Putin just sowed it up. He won. It's checkmate. Any opposition would have to turn the table over with the whole world watching. Who'd back that "player," that sore loser?
I don't care if the sore loser is the US run by maniac neocons or not, I would not go along with any so-called US government ruining the peace prospects for Syria. I don't care what guise it would come under either. The Syrian People alone shall democratically decide their constitutional form of government and their leader. The US government (the US neocons) can butt the hell out.
