Bob Drogin of The New Republic interviews weapons Iraqi scientists here (four week free trial subscription). The Iraqi scientists are uniformly fearful of Saddam, but none have taken the American $200,000 cash reward and political asylum or a new identity outside Iraq either.
Sounds to Drogin like Saddam refused to admit he no longer had WMDs for fear of losing his grip on power, and because he believed that fear of his weapons deterred coalition forces in the first Gulf war. So the sanctions, and the inspection regime, were working. Remind me again what the case for war was?
