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

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.

If there's ever an example that military power alone cannot be successful in Afghanistan, I think it was the Soviet experience.

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

I read in the press, and therefore it must be true, that no secretary of defense had ever been quoted as arguing for a bigger budget for State.

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

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?
