Tony Blair's Red Herring

Here's a bit of a bizarre story. Tony Blair claimed in an interview that the Iraq Survey Group had found "massive evidence of a huge system of clandestine laboratories, workings by scientists, plans to develop long range ballistic missiles". Paul Bremer, commenting on the quote, not knowing that it came from Blair, responded, "I don't know where those words come from but that is not what (ISG chief) David Kay has said. ... It sounds like a bit of a red herring to me. It sounds like someone who doesn't agree with the policy sets up a red herring then knocks it down." Doh! And can anyone explain why this WMD thing has apparently fizzled out? I always thought it put Blair at more risk than Bush, but it doesn't appear to have done any significant damage to either...
