Hans Blix, PhD Biography

"...[T]hey [the United States and Britain] certainly advanced weapons of mass destruction as the decisive reason for going to war, and I think the evidence was rather weak at the time. We had heard in the autumn of 2002 that the alleged aluminum tubes, for instance, which were thought, alleged to be for making the centrifuges, were probably more likely to be for making a rocket. And in January 2003, we had performed quite a lot of inspections to sites which were given by intelligence and they had not shown any weapons of mass destruction, so we began to be doubtful.

And among the 700 inspections that we performed, none brought us any evidence of weapons of mass destruction. I warned the Security Council about that. Yet, there might have been other evidence and Colin Powell came before the Security Council and he brought some evidence, which we could not check. And I think that by now most of the evidence has fallen apart."
