In the past, Saddam DID possess WMDs - chemical and biological. He showed a perfect willingness to use them, both on foreigners in the Iraq/Iran war, and on his own people (Kurds in N. Iraq, Shia in S. Iraq). Furthermore, his actions as a mass murderer with his very own set of mass graves, should, for any decent human being, provide more than sufficient justification for invasion of Iraq, capture of Saddam and his buddies, and Hanging by the Neck Until Dead for that set of Hitler-wanna-be's.
