yeah, i've been following that. there are several good articles about it on slate.com right now (just go to the front page, you'll see).
it's hard for me to criticize Bush for not finding the WMDs and say "this impugns the war", because from the beginning i've held the point of view that WMDs were absolutely meaningless to the justification for war. and now, it seems, i'm vindicated when i said that, "If Bush had just said this was a war primarily to free the Iraqi people rather than scaring Americans with all this self-defence and WMD nonsense, the simple fact of 'going to war' would be a lot harder--if not impossible--to credibly attack."
what i think Bush should be doing is pushing the we-toppled-Saddam thing. it's inarguably a good thing--even the most Bush-hatin' liberal has to agree. that wuold require Bush to admit his massive dishonesty in selling the war to the uninformed American populace as a defencive war, though, and he might not survive that come November.
