I think, on the foreign policy side, that there is a need for disruption. We've had three administrations follow a pretty consistent policy toward North Korea, and it really hasn't gotten us anywhere.

We should never lose sight of the ethos that has made the Marine Corps - where 'every Marine is a rifleman' - one of America's cherished institutions and one of the world's most feared and respected fighting forces

I consider myself a Republican.

Development is a lot cheaper than sending soldiers.

What I know concerns me. What I don't know concerns me even more. What people aren't telling me worries me the most.

I think it's kind of a stretch. You know, it's one thing if somebody working for the U.S. government has sold secrets to the other side, it's another if they have something in their personal life that they're hiding for which they could be blackmailed. Having evidence that they didn't tell the truth to somebody in the same building where they work, maybe it's just the old intel guy, is - it's a problem.

Most governments lie to each other. That's the way business gets done.
