There was always going to be a reckoning. Ideally, American allies would defeat the world’s most vicious terrorists, the warring parties in Syria would then have the space to reach a political settlement, and a genocidal civil war would finally end. Yet when ideals meet the hatred and confusion of the Middle East, ideals always lose. So rather than staring peace in the face, we’re not only raising the risk of direct and sustained confrontation with Syria (and its chief ally, Russia), we’re inching toward an outright invasion and extended occupation of northern Syria. All without congressional approval. All without meaningful public debate.
