If by UN declaring a civil war in Syria classifies atrocities as war crimes, US covert forces there are war criminals

UN observers have now labeled rebel clashes in Syria as having escalated into “Civil War”, initiating the legal foundation to go after Syrian president Assad on charges of “war” crimes. It’s a welcome bit of sophistry and should cut both ways. If the insurgent groups are armed and lead by covert special op forces of the US and NATO, then who are the bigger war criminals? So far the massacres ascribed to Assad, provoking Hillary Clinton’s condemnation, have proved to be the work of US-allied rebels.
