Just a couple of years ago the Donald was adamantly against attacking Syria, what happened sweetie? You don't get to have it both ways
I guess Trump got tired of the rest of the world thinking the US is a coward after Obama backed down from his own Red Line.
Trump was against dragging the US into an Un-Constitutional, Un-Authorized war in which Obama would send a US invasion force into Syria, putting US combat troops in Syria.
Trump just showed Barry there was a better way - by conducting a one-time, precision strike proportional military response that just destroyed the airbase from which Assad's chemical weapons attacks came.
You actually CAN have it both ways, 'sweetie' - you can actually send a message that using chemical weapons will not be tolerated without dragging your country into the middle of a civil war between terrorists and a Russian-protected dictator without Congressional approval to do so.
