This is the speech Charles Krauthammer gave at the AIE Annual Dinner in Washington on February 10, 2004.

Excerpt:

Whether or not Iraq had large stockpiles of WMDs, the very fact that the United States overthrew a hostile regime that repeatedly refused to come clean on its weapons has had precisely this deterrent effect. We are safer today not just because Saddam is gone, but because Libya and any others contemplating trafficking with WMDs, have--for the first time--seen that it carries a cost, a very high cost.
