If you think I would have gone to war the way George Bush did, don't vote for me.

We achieved a deal with the Russians that didn't wind up in two days of strikes that would have sent a, quote, "message," but would not have removed the weapons. We struck a deal to get all of the declared weapons out of Syria. Never before in a conflict has that ever happened, that during the conflict weapons of mass destruction are taken out of the zone of conflict. And thank God we did that, because if we hadn't done that, today ISIL would have those chemical weapons in large parts of the country.
