As a followup to the accusations that the Bush Administration was the source of the claim that Iraq had WMDs, the following article on CanadaFreePress.com has more evidence to the contrary.
bi: I was more rebutting the common misconception that the Bush Administration was the original source of the claim that Iraq had WMDs more than I was responding directly to the particular Slashdot poster's false claims.
It's interesting that you bring up Hans Blix. As has been noted by every director of the UNSCOM (including Blix himself), Iraq has had a history of being uncooperative with the weapons inspectors. Suddenly this changed in 2003.
It could be argued that it was because Iraq had finally finished getting rid of / dismantling their WMDs/programs and no longer had anything to hide, and I think this argument is plausable.
haruspex says "Gosh, just maybe they cooperated because they didn't want their country destroyed?"
I think that's another very good theory - I'm sure Iraq was confidant that the United States would likely invade by that point.
Anyways, back to bi's assessment that Bush had other motives for invading Iraq other than the WMDs, I am inclined to agree.
