ofcourse the us is itching to go at syria.
they have long since weaponised "human rights".
the us dont give a crap about the syrians, in fact they were itching for some massacre to occur to provide international hue and cry.
they have also facilitated the bloodshed as BEST they can by sending provocateurs, the russian position is the most peaceful, these rebels are not legitimate in any sense and do not represent the majority, they in fact need to listen to the law, not make their own.
this is merely another face of imperialism - "we are killing you because we care about you".
