To arm or not to arm? That was the question vexing our Hamlet of the Potomac as he grappled with the Syria problem.
Fortunately, he had a lot of angst and recognized it as a troublesome, nuanced problem, so libs who would otherwise be appalled by this decision to arm the rebels can be reassured - the President is no more committed to our current course of action than they are. His application of the Powell doctrine is that he didn't break it and he is damn well not going to own it.
A few years down the road his daughters will be arrested as part of their role in anti-war demonstrations, so its all good.
