How can you defy fear? Fear is a human instinct, just like hunger. Whether you like it or not, you become hungry. Similarly with fear. But I have learned to train myself to live with this fear.
I believe that sooner or later we're going to have to deal with Saddam Hussein, because of his general reputation, because of what I'm convinced he's done with regard to terrorism and the support thereof. But I'm not at all sure I believe that it has to be right now.
