Bobert, Terrorists do not completely rely on state support to conduct their operations, but they do need some states to provide safe havens, and money laundering services. Saddam is one of the few states who supports Bin Laden with impunity; and is most probably the only place he would be safe to arrange his campaign in.

Work the rest out for yourself. If Bush doesn't destroy the infrastructure of support, then Saddam can supply biological, nuclear, chemical warfare supplies to the kind of terrorists who would "deliver" them in person. The people of Iraq are desperately in need of liberation from this dictator. The war is not aimed at them directly, but they stand to lose the most in any military action. The United Nations are proven impotent and unwilling to take action, they will not enforce anything, any action taken will be up to the USA in the end.
