I consider myself a Republican.

I've seen, all too often in my career, people coming in to lead agencies and organizations and trying to impose change from the top down. Never works. You never have enough time.

I will always be an advocate in terms of wars of necessity. I am just much more cautious on wars of choice.

Things have gotten so nasty in Washington.

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.

Some people have said, in so many words, that I'm kind of wooly-headed in believing that the Iranians would see not having nuclear weapons as more in their security interest than not.

In government, I'm a strong believer in the need for reform of government agencies and departments. They - they have gotten fat and sloppy, and they're not user friendly. They are inefficient. They cost too much.
