Today, we are warned by John Kerry and others that if we don't act with lethal force, the Syrian government will kill thousands more people. Let's not be deluded: When we do intervene militarily, the Syrian government (and we) will kill thousands more. And anti-Assad forces will also kill more. We've been reminded often in the past few weeks that chemical weapons are awful -- and carefully not reminded that conventional weapons are too. It's tragic when civilians are killed by their own countrymen or when foreign civilians are killed by our countrymen. It's tragic when our soldiers are killed or when their soldiers are killed. But none of those tragedies will be influenced by the political posturing this week. Rather, the result of congressional hearings is that responsibility for the attack(s) on Syria will be distributed more comfortably for all concerned, and there will be a more comfortable consensus about which of these tragedies are necessary evils.
