In my particular case foreign policy happens to be my hobby, my consuming interest. I had spent decades studying it.

The conventional army loses if it does not win. The guerrilla wins if he does not lose.

With respect to the relationship between nuclear weapons and the advent of détente, one has to consider two things. One, the nature of nuclear weapons in themselves, and secondly, the advent of nuclear parity.

Well, he keeps saying that, and as defense secretary, of course he has to think of a lot of potential enemies. I do not think it's a wise course to articulate this or to base our policy on it. And I do not see under modern circumstances what we would be fighting about.

Let me make my point about Vietnam. When the Nixon initiation came into office, there were 550,000 Americans in combat. And ending the war was not a question of turning off a television channel. And so, debating on how we got there and what judgments were made was not going to help us.

What China would do, I cannot predict. China has all but given up the claim to the use of force, except in the circumstance of Taiwan declaring its independence. That is a huge step forward over what the situation was many years ago.

I can think of no faster way to unite the American people behind George W. Bush than a terrorist attack on an American target overseas. And I believe George W. Bush will quickly unite the American people through his foreign policy.
