If the Obama administration (i.e. Obama himself) had any integrity he would have supported the Syrian rebels back when he also supported the protesters in Egypt or the rebels in Libya.
Of course, that would have required showing some backbone on the global stage, and right now it looks like he can’t even manage that with a WMD-based provocation.
I’m not saying attacking Syria now is right or wrong. But it is no more right now than it would have been a couple years ago. In short, the Bush policy of preemption remains the right thing to do.
