NATO was formed post-World War II. We're a little bit more than a half-century old. Do we want NATO to go on for another half-century? I think that the answer is, sitting here today: I don't know. If I had to bet on it, I would say, yeah, we have to have these alliances going forward and see who's going to pay for them.

Donald Trump is a great listener, and he's a good challenger. He doesn't come across as a person who thinks he knows it all. In fact, he once told me he has had lot of things to learn.

Islam is an ideology and there's a religious component to it that's radicalized and in some cases it masks itself behind that religion, especially in America, because of freedom of religion.

Why do we take a dollar? Why do we give a dollar to countries that have no rights for women? We have to think about that.

It's not Islam, it's extremism in general, that is such a crock and that does a disservice to the people of America to make us sound like we're a bunch of idiots that we can't see what's going on in front of us and we're too weak to tell the truth.

The threat of nuclear warfare is very, very low. Trump is no fool, and he sees the world as a globalized world.

Why are all these refugees rushing to the beauty and strength of Europe and to the United States and not rushing to their own capitals or the capitals of the Muslim world? We ought to be pushing back. We ought to be putting people back on these boats and putting them back into the places where they came from and telling these leaders in the Arab world, "You have a responsibility as well."
