What’s worse: Launching a disastrous military campaign under false pretenses to achieve goals you wrongly believe are attainable? Or launching a disastrous military campaign you know is doomed in order to help your party win an election?

I ask in light of today’s New York Times story about how President Obama asked the CIA a while back whether arming rebel forces – pretty much the agency’s signature strategy — had ever worked in the past.

He was told that it almost never has.

But then in June, once the political pressure for intervention in Syria got too great, he did just that — sending weapons to rebels fighting the Syrian military.

Yes: He knew better, but he did it anyway.
