This must be a joke , Assad Kinda won the war . i Doubt he will be leaving anytime soon .
 We have seen last time the US have Decided the faith of a Country Libya ,Iraq and now Syria. Nothing good ever comes out of it . US is Still playing that Cold War with the Russians . 
Not a single Arab Country has benefited From the Arab Spring  .American interference/invasion  Is not the solution for every political problem in the world  .
