A positive attitude is not going to save you. What it's going to do is, everyday, between now and the day you die, whether that's a short time from now or a long time from now, that every day, you're going to actually live.
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.
