If you take a look at Afghan history, usually they have united to defend against an outside enemy, and as soon as that's accomplished, they turn and start killing each other. This internal instability is a constant invitation to outside forces to come in. I have to think that after the awful years of the Taliban, most Afghans would want to remain at peace, and get the benefits of the new freedom they've found. But I can't be sure that old habits won't reassert themselves.

The consequence of a world full of nuclear powers to me is so incomprehensible in terms of the dangers that that implies.

There's Hezbollah, there's Hamas, there is a whole range of terrorist targets out there related to Palestine and to Israel that we ought to be trying to deal with. And there's a great deal of targets in the Philippines, Indonesia. You name it, there are a number of places where there are targets that we ought to be trying to deal with.

The point is, once they have a missile that can hit the United States, we are now back in the kind of game we used to worry about with the Soviet Union, only the Soviet Union was more mature about this whole thing than I think the North Koreans will be.

There are a lot of other terrorist targets we ought to be focusing on. Well, there is Syria, for example, which is pumping through - because of Iran, is pumping weapons on into Hezbollah and so forth - which is then producing a lot of agony in Palestine and in Israel. We ought to be doing a bit to try to stop that.

My own view of this, by the way, is, if the war on terrorism is successful over time, in its own way it's going to box Saddam in in a way that's going to make it much more difficult for him to maintain his power, and that he's going to become increasingly isolated. I think that's going to take time.

If George Bush [Jr.] decided he was going to turn the troops loose on Syria and Iran after that he would last in office for about 15 minutes. In fact if President Bush were to try that now even I would think that he ought to be impeached. You can't get away with that sort of thing in this democracy.
