Eactly. Even if he didn't have WMD, which I doubt, Saddam was a dictator with the intention of pursuing WMD.
Additionally Saddam reportedly financed terrorism (giving money to the families of dead Palestinian homicide bombers).

He was funding terror by arranging the killing of Jews with bombs in Israel.
That was enough right there.
