Saddam will only use his WMDs when he knows that all is lost. He probably thinks that if he can just hold on long enough, world opinion will force a halt to the war, leaving him in power.
If he uses chem or bio weapons otherwise, he proves that Bush and Co. were right all along.
It was reported tonight that a unit in the northern approaches had found "equipment and documents" that indicated the presence of chemical weapons.
By the way, most modern countries have bio and chem warfare labs. Why? simple. You have to be able to study chem/bio agents in order to figure out ways to counter them. Yes, I know that they are illegal for use in warfare under the Geneva Convention. That didn't stop the Iraqis or the Iranians from using them, did it?
