You are laughing at what? What he said is in part the truth...after 12 years of their BS we just got tired of fucking with them and this in part is one of multiple reasons that the US invaded. WMD's/materials was also just a part of the public face put forth for the invasion...though a major part.
The Congressional Select Intelligence Committees...will be the determiners about the truth of the Administration as pertains to WMD's/materials, or if there was a massive intelligence failure. If there is an intelligence failure it certainly is not the first time nor will it be the last time.
