Stopping the worst people on earth

According to Obama’s own assertions, however, the recent Kurdish/Iraqi advances have averted the threat of genocide. As for the threat to U.S. personnel at the consulate in Irbil, it, too, is reduced.

It was a flimsy rationale to begin with. To protect Americans in an outpost, you don’t need an air war. A simple evacuation would do.

Besides, what does the recapture of the Mosul dam, the most significant gain thus far, have to do with either rationale? There are no Christians or Yazidis sheltering there. Nor any American diplomats. So Obama tried this: If the dam is breached, the wall of water could swamp our embassy in Baghdad.

Quite a reach. An air war to prevent flooding at an embassy 200 miles downstream? Well, yes, but why not say the real reason? Everyone knows it: The dam is a priceless strategic asset, possession of which alters the balance of power in this war.
