Rumsfeld weakens a pillar of war

Don Rumsfeld with something surprising today:

The actual words Mr Rumsfeld used in his comments on Monday to the Council on Foreign Relations in New York were: “To my knowledge, I have not seen any strong, hard evidence that links the two.”

He also said he had seen the intelligence “migrate in amazing ways”, without explaining what that meant.

His statement was in marked contrast to what he said in September 2002 when he described the evidence of a link as “bullet-proof.”

This comes at the same time as Paul Bremer saying that there were not enough troops on the ground after the invasion. Rummy seems to be getting tongue tied here, he was so certain 2 years ago, he stated as “fact”. His words. Now he is not sure. Does all this constitute a lie?
