This revolution began with young people in Syria demonstrating because they wanted a future. They wanted opportunity, education, and so forth. They went out and they did it. Thugs came out and beat them up. The parents got angry that the thugs beat the kids up, and they went out and demonstrated, and they were met with bullets. They were killed. That's how this began.

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.

You just don't invade another country on phony pretext in order to assert your interests!

I don't want to claim that God is on our side. As Abraham Lincoln told us, I want to pray humbly that we are on God's side.

If Russia is there [in Syria] alone fighting them [ISIL], guess what? Russia becomes the target and Russia starts seeing - who knows - MANPADs will find their way in there, airplanes will fall out of the sky. They will become vilified. They'll become the new magnet, together with Assad, for the jihadis.

Sunni are the majority of the [Syria], 60 to 65 percent. They've been ruled by [Bashar] Assad, who represents a minority Alawite element, which is about 12, 13 percent. And because of the choices Assad made, it's very difficult to see how you resolve this without buy-in from the Sunni world.

Reduce US military presence in Iraq; and bring in neighbors.
