No one is arguing that all the intelligence that came out of Iraq was accurate. That's abundantly clear to everyone. The issue that seems to be debated is that Hussein presented no threat, they didn't have a weapons program, and that they had no illegal weapons. And that's all untrue.
But, those same people arguing those points also tend to be the same ones who also argue that the cell in Buffalo was harmless, the attack on Ft Dix could never have happened, and the JFK bomb threat was a fluke thing.
