Go visit the 40 towns Saddam bombed with mustard gas and tell them Saddam didn't have WMD. Speculation and investigation are one thing, but a picture's worth a thousand words.
Besides, this failed to quote the portion where Bush mentioned Iraq had failed to disarm for 12 years and that the US had causa belli (yes, Bush used that word, though I prolly mispelled it) to go in. He also stated he went to the UN and told them to do something or the coalition would -- he gave them the chance. As I recall it, they turned to a lengthy discussion about what the pres said rather than turning to dealing with Saddam."Feckless debate" were his words, IIRC. A very good interview, though misrepresented in the article you posted.
