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.

Remember the hours after September 11th when we came together as one to answer the attack against our homeland. We drew strength when our firefighters ran upstairs and risked their lives so that others might live; when rescuers rushed into smoke and fire at the Pentagon; when the men and women of Flight 93 sacrificed themselves to save our nation's Capitol; when flags were hanging from front porches all across America, and strangers became friends. It was the worst day we have ever seen, but it brought out the best in all of us.

The consequences of a crime should not be out of proportion to the crime itself.

I do think that it's really important for leaders of countries to be very clear and careful in the statements they make because their words are weighed extremely carefully by other countries, and you have to create a continuity of seriousness and of credibility in order to be able to be taken seriously and get things done.

I mean, all of these things that [Bashar Assad] has done, there's no way even if President Obama wanted to just play along that you could actually achieve peace, because there are 65 million Sunni in between Baghdad and the border of Turkey, Syria, and Iraq, who will never, ever again accept Assad as a member - as a legitimate leader.

And if [Vladimir Putin] does fight ISIL alone, how does it work out for Russia to have sided with Assad, sided with Iran, sided with Hizballah, when they're trying to reach out to the rest of the Sunni world in the region? That's not a good equation for Russia.

Unlike George Bush and his friends at the big oil companies, I'm going to work for a real energy policy for this country that decreases America's dependence on foreign oil and helps lower the costs to American families.
