I am no fan of Assad but the people who are going to Replace him Hint - Al Queda
how will Replacing Bad With Badder benefit The united states not to mention the Syrians who will Blame the US & it's allies for demise of their country
It will be good for Saudi Arabia etc. They pretty much control AQ. The most powerful countries in the ME want Assad out, and theres no way he can win against such pressure.
