A fundamentalist can't bring himself or herself to negotiate with people who disagree with them because the negotiating process itself is an indication of implied equality.
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.
