Well, I've ruffled a few feathers at all the institutions I've led. But I think that's part of leadership.

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.

Congress is best viewed from a distance - the farther the better - because up close, it is truly ugly.

I think that Iran with a nuclear weapon is extremely destabilizing. I think it could precipitate a nuclear arms race in the region.

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.

I'm a big advocate of drones.

I have tried to maintain civil relationships with everyone I meet - and, even if I violently disagree with them, try to be respectful.
