If you read David Kay's report, you'll see that there was indeed a WMD threat from Saddam.
I haven't read the whole report, only excerpts given to press agencies. Some of these excerpts said Iraq was indeed working on such weapons, but other said quite the contrary. And, alas, Dr Kay himself made contradictory declarations.
Quite frankly I'd much prefer the issue to be either abandoned or backep up by a undisputable find.
