I think it's a very reasonable thing to be concerned about. I don't worry in particular about what the major nuclear powers are going to do. I don't think France, England, and the United States are going to treat these matters easily. To take North Korea as an example, I don't think it would take a great deal for a match to be struck and something to happen there. North Korea has a number of tactical nuclear weapons, and I think that if it ever really felt threatened, it would use them. I think one of the things we need to remember is, whether they're tactical or strategic, the population at large doesn't really distinguish. It's going to scare the living daylights out of people. We need to be very careful about any thought of using tactical nuclear weapons. When the United States mentioned this as a possibility a while ago, it was really concerning.
Pakistan is a nuclear state, and it allegedly has some tactical nuclear weapons. I really worry about whether their security is as good as it could be. Pakistan goes to a considerable length to make sure that's the case, but that part of the world is very unstable. I was arguing earlier that NATO should have a diplomatic component as well as a military one. I think one really good area for Mr. McRae's successors and colleagues would be to push very hard for the elimination and greater control of tactical nuclear weapons. When one is used, it's going to be very hard to back away, because of the psychological impact, not necessarily the military impact.
I hope that's helpful.
