Every time we have come to the end of a conflict, somehow we have persuaded ourselves that the nature of mankind and the nature of the world have changed on an enduring basis and so we have dismantle our military and intelligence capabilities. My hope is that as we wind down in Iraq and whatever the level of our commitment in Afghanistan, that we not forget the basic nature of humankind has not changed.

I consider myself a Republican.

One of the big changes in the Congress since I first came to Washington is that all of these folks go home every weekend. They used to play golf together; their families got to know each other, go to dinner at each other's homes at weekends - and these would be people who were political adversaries.

No policy has proved more successful in making friends for the United States, during the cold war and since, than educating students from abroad at our colleges and universities.

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 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.

One of the toughest battles in intelligence is combating conventional wisdom.
