From your own source:

"The dictator who is assembling the world's most dangerous weapons has already used them on whole villages -- leaving thousands of his own citizens dead, blind, or disfigured. Iraqi refugees tell us how forced confessions are obtained -- by torturing children while their parents are made to watch. International human rights groups have catalogued other methods used in the torture chambers of Iraq: electric shock, burning with hot irons, dripping acid on the skin, mutilation with electric drills, cutting out tongues, and rape. If this is not evil, then evil has no meaning. (Applause.)

And tonight I have a message for the brave and oppressed people of Iraq: Your enemy is not surrounding your country -- your enemy is ruling your country. (Applause.) And the day he and his regime are removed from power will be the day of your liberation. (Applause.)"

It is a flat out lie to claim WMD were the only justification. It was the major concern as indicated by the relative time spent, but not the only one. You would also do well to review more of that source on why we thought Saddam had WMD. It was his responsibility to show he did not and ours to respond if he didn't.
