You're absolutely correct. The key word, however, is had, as in past tense. More and more evidence suggests that prior to the invasion no WMDs existed. Therefore there was no imminent threat to the world, no link to al Quida, nothing to disarm, ergo, no reason to invade.

And the argument, "Doesn't matter, we're better off without Saddam around" is not the issue here. The issue is that the American people were convinced that weapons existed, there was an imminent threat, and there was a link between Osama and Saddam. We're finding out now that the administration grossly abused its power to mislead the American people. Nixon was the last to do that and he had the integrity to resign.
