US foreign policy of regime change fermented this bloody civil war which became another proxy war on their behalf.  The US and their vassals are on the wrong side of history here.  As for the UN, they seem to be nothing more than a mouthpiece for US hegemony and can't see the forest for the trees.  The entire politico, behind the destruction of the Middle East is corrupt and working with the US military complex against the interests and wishes of their citizens.  The US, ironically has become the very "evil empire" which they are so quick to accuse others of.
