I think you just can't admit to the possibility that the US administration knew very well all along that Saddam was no threat, but simply pretended he was, because they had other reasons for wanting to invade Iraq.

I remember when the Iraqis dismantled those not very formidable short range missiles they had...and were bitter about it. What a joke. It was pathetic. They could have done anything, complied with anything, and they would still have been invaded. The decision had already been made way in advance by Washington and the UK, the rest was just phony PR to make it look good to the public.

Hitler was a real threat. Saddam was not. He couldn't even defeat Iran in the 80's, and he got a lot of outside help in the form of high tech weapons to do that.
