TourDeForce, I think you are missing the point of the article. The article doesn't say there NEVER was ANY evidence of WMDs. It says that the Bush Administration deliberately misused intelligence to make a phony case for war.
We all agree there was SOME evidence of WMD programs (long before the war, anyway). But insiders like Pillar are telling us that the evidence showed that Iraq was never an imminent threat to our security. Bush took a bit of evidence here and there to cook up a horrible immediate (albeit imaginary) threat to justify his war.
