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.

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.

NATO as a political alliance does need to be relooked at in terms of everything - resourcing, capabilities.

What do you do when you get out of the military, you stop serving? There are 26 presidents who served in the military. More than half of our presidents... that means that you stop being an American?

If there's a way to serve America, I'd always consider it.

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.

I do care about the direction of America.
