Donald Rumsfeld's comments to Congress on July 9, 2003.
The coalition did not act in Iraq because we had discovered dramatic new evidence of Iraq's pursuit of weapons of mass murder," Rumsfeld said.
He said the terrorist strikes on New York and Washington in 2001 "changed our appreciation of our vulnerability" to attacks with chemical, biological or nuclear weapons.

(CBS/AP) Defense Secretary Donald Rumsfeld on Wednesday told Congress that the U.S. invaded Iraq not because of a new threat of weapons of mass destruction but because of new fears they might be used.
"The coalition did not act in Iraq because we had discovered dramatic new evidence of Iraq's pursuit of weapons of mass murder," Rumsfeld said. "We acted because we saw the existing evidence in a new light through the prism of our experience on Sept. 11."
