This link which offers a gobsmacking declension of WMD quotes.

It starts with ...

"Simply stated, there is no doubt that Saddam Hussein now has weapons of mass destruction."
(Dick Cheney August 26, 2002)

and ends with

"It was a surprise to me then — it remains a surprise to me now — that we have not uncovered weapons, as you say, in some of the forward dispersal sites. Believe me, it's not for lack of trying. We've been to virtually every ammunition supply point between the Kuwaiti border and Baghdad, but they're simply not there."
(Lt. Gen. James Conway, 1st Marine Expeditionary Force May 30 2003 )

Mind you, I don't doubt the existence of WMDs. My source and his evidence is impeccable ...

"The president of the United States and the secretary of defense would not assert as plainly and bluntly as they have that Iraq has weapons of mass destruction if it was not true, and if they did not have a solid basis for saying it,"
Ari Fleischer as reported in the New York Times.

I rest their cases.
