Former Defense Secretary Donald Rumsfeld told CNN that if the U.S. knew Iraq had no weapons of mass destruction, it probably wouldn't have decided to invade.
"Rumsfeld noted there were multiple reasons for attacking Iraq and ousting Saddam Hussein from power. However, intelligence reports -- now shown to have been false -- that Iraq possessed so-called WMDs was the main reason for going in, Rumsfeld said."
Said Rumsfeld, when asked if the Bush administration would have decided against invasion if it didn't think Iraq had WMDs: "I think that's probably right."
