I have a couple of quibbles. First, Mr. Doolittle cites David Boucher:
Iraqi contacts feared that if they were to allow full inspections, the United States would become too informed about Baghdad’s defense capabilities and therefore Iraq would be more vulnerable to attack.
I prefer to think Saddam stopped cooperating because UNSCOM had been infiltrated by US intelligence, which used various methods to gather information on Saddam's location -- in preparation for a "decapitation strike." If so, his fears were justified, since Operation Desert Fox appears rather like a failed decapitation strike.
Second, Mr. Doolittle cites
Newsweek:
So, after Saddam’s son-in-law Hussein Kamel, head of his unconventional weapons programs, defected to Jordan in 1995, Saddam ordered intensified efforts to hide or destroy blueprints, ‘dual use’ technology and any remaining germs or chemicals.
But Mr. Doolittle neglects to mention that Hussein Kamel reported all the WMD were destroyed in 1991.
As for the claims that US intelligence was duped by fake defectors, all I can say is that Cheney and company were more than willing to read into defector reports whatever suited their policy goals. I don't think it's necessary to invoke fake defectors to explain delusional assumptions at the White House.
