I had no concerns - I had no reason to have concerns based on what was available to me about North's contacts with the private sector people, but I didn't think a CIA person should do it.

I have always that there ought to be some kind of mandatory national service, not necessarily in the military but to show everybody that freedom isn't free, that everybody has an obligation to the nation as a community.

I mean, when you get down to very low numbers of nuclear weapons, and you contemplate going to zero, how do you deal with the reality of that technology being available to almost any country that seeks to pursue it? And what conditions do you put in place?

I've been very sensitive for a long time to the repeated pattern, during economic hard times or after a war, of the United States' essentially unilaterally disarming.

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've spent my entire adult life with the United States as a superpower and one that had no compunction about spending what it took to sustain that position. And it didn't have to look over its shoulder because our economy was so strong.

If Iraq and Afghanistan have taught us anything in recent history, it is the unpredictability of war and that these things are easier to get into than to get out of, and, frankly, the facile way in which too many people talk about, 'Well, let's just go attack them.'

If Poindexter made a comment to me like that, it would have been in the context of once the authorized program is approved there would be no point in having any of these private benefactors any longer.

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.

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.

The reality is, the United States has global interests. Our defense budget is about the same as the defense budgets or military budgets of every other country in the world put together.

There is no international problem that can be addressed or solved without the engagement and leadership of the United States and everybody in the world knows that, its just fact of life. So sometimes I think we could conduct ourselves with a little more humility.

Well, what I've said is that the war in Iraq will always be clouded by how it began, which was a wrong premise, that there were in fact no weapons of nuclear - weapons of mass destruction.

When I was the director of Central Intelligence in the early '90s, I tried to get the Air Force to partner with us in building drones. And they didn't want to, because they had no pilots.

A wild and crazy weekend involves sitting on the front porch, smoking a cigar, reading a book.

One of my favorite little sayings is, 'To avoid criticism, say nothing, do nothing, be nothing.'

Defense is not like other discretionary spending.

Health care costs are eating the Defense Department alive.

I consider myself a Republican.

I don't think any president that I worked with has ever said 'pretty please.'
