I can't take my Catholic belief, my article of faith, and legislate it on a Protestant or a Jew or an Atheist. We have separation of church and state in the United States of America.

When I was in Vietnam I learned a lot about the promises that soldiers make to each other. The Marines have a promise to never leave behind their dead. In this country, as citizen soldiers, we need to make the commitment to each other that we will never leave our veterans behind.

Three-quarters of [Bashar Assad] country is displaced. It's in Jordan, it's in Lebanon, it's in Turkey, and in the desert. The threat is that those people in the desert and others could become the next acolytes of ISIL if we don't find a way to join together to go after ISIL.

We have to recognize that there is a strong, fresh wind blowing, powered by these new information technologies. It will be increasingly difficult for dictators to impose their will through sheer brutality.

We do have to take the long-term view. And long term, the question to ask ourselves is whether America should attack others pre-emptively, whether she should embroil herself in wars far away from our soil, and try to bring democracy by force to the rest of the world.

[Bashar] Assad himself has said on several occasions recently that if the people of Syria don't believe I should be there in the future, then I would step - I would leave. He has said it. He has, on occasion, hinted that he wants a political settlement of one kind or another. I think it's up to his supporters, his strongest supporters, to make it clear to him that if you're going to save Syria, Assad has made a set of choices - barrel bombing children, gassing his people, torturing his people, engaging in starvation as a tactic of war.

The big hang-up was George Bush wanted to get life lines, you know, so he could call somebody.
