Bush gave some hints that our intelligence knows a lot more about what is going on. The rebuttal I've heard is 'why aren't they telling the inspectors?'.
Well, if you know that some of the inspectors aren't clean, that a Frenchie was sneaking a peek at the schedule of the inspector's visits, and that Iraq is pulling stunts like having secret police pose as scientists, would you really be stupid enough to pass on intelligence info?
Resolution 1441 doesn't require us to tell the inspections where to find hidden stuff. Nor are the inspectors required to find the infamous smoking guns.
Iraq is supposed to be bring the inspectors in and showing them where WMDs are and asking for help to disarm the WMDS/
The smoking gun is something our left wing politicos and ABCNNBCBS came up with.
