I opposed the U.S. involvement in Lebanon. We ended up having to withdraw our marines after our barracks were blown up.

I was the chairman of the Budget Committee and the lead architect the last time it happened in Washington, and when we did it we had great economic growth, we cut taxes, and we had a big surplus.

(God) wants America to succeed. And he wants America to lead.

I've been frankly very surprised at the intensity of our differences [with Russia]. I mean, between what appears to be hacking of our political system to the aggressive use of nukes on the borders, to these atrocities in Syria and their warnings. I've been very, very surprised at the intensity of all this.

If we intend to provide a better life, and a better world, for future generations, we can't ignore the quality of the environment we leave them.

Republicans and Democrats spend so much time fighting and then they're all aghast, you know, and so it's just not the way we ought to be. The coarseness is not acceptable.

We've just let too many things happen. And now, try to turn around and fix it. Getting involved in a [Syria] civil war directly was never something I thought made sense.
