When you look back, history is not going to be kind to these last 16 years from 2000 to 2016.

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.

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

There's one thing that I know about myself, I could wash dishes and be happy.

You look at Libya, and you go, "Jesus, why the hell did we do that?" That's beyond stupid. That's so irresponsible and dangerous for our national security and frankly for the national security of Europe because you go and you look at where a lot of these refugees are coming out of, they're coming out of Misrata and Tripoli.

We have a problem with radical Islamism and I actually think that we could work together with Russia against this enemy. They have a worse problem than America does.

I grew up as a kid with very little. I could enjoy a peanut butter and jelly sandwich or peanut butter crackers.
