You are assuming he did, and that he fully understood the op. Remember, he can't stand the daily briefings. Maybe he's out of the loop on some of the decisions.
He likely is. Definitely. I think the military said “screw Obama”, and is actively getting the job done. I mean, I’m sure orders are coming down. But they are probably left to commanders discretion.
Baghdad Barry is completely out of the loop on this. He's too busy sulking and pouting about the keester-whooping he got on Tuesday for anything else. Somebody near the inside in Mosul (Kurds? Mossad?) IDed Baghdadi and was able to get word to our guys and they just let'er rip. There was "no time" to get Washington involved so that there could be 48 hours of hand-wringing about the decision.
