Charles Krauthammer says it all:
Yet consider what’s happened over the last month. Assad uses poison gas on civilians and is branded, by the United States above all, a war criminal. Putin, covering for the war criminal, is exposed, isolated, courting pariah status.
And now? Assad, far from receiving punishment of any kind, goes from monster to peace partner. Putin bestrides the world stage, playing dealmaker. He’s welcomed by America as a constructive partner. Now a world statesman, he takes to the New York Times to blame American interventionist arrogance — a.k.a. “American exceptionalism” — for inducing small states to acquire WMDs in the first place.
And Obama gets to slink away from a Syrian debacle of his own making. Such are the fruits of a diplomacy of epic incompetence.
