No WMD is all about the future and not the past
I can certainly see Will's point and I don't disagree.
GWII was a justified war and it is behind us. Bush's future popularity does not and will not hinge on finding the weapons unless he guilty of a massive plot to deceive the people.
What the people that opposed this war should be celebrating is that without finding the weapons the bar has forever been raised for pre-emption. As much as I supported the war, based on my expectations and the outcome and as much as I am convinced that Bush's motives were decent, I will not support and I doubt that Bush will promote future adventures without universal support and/or unquestionable proof.
