...Saddam falsely allowed the world to believe Iraq had weapons of mass destruction - the main U.S. rationale behind the war - because he feared revealing his weakness to Iran, the hostile neighbor he considered a bigger threat than the U.S.

The notes of the FBI interviews were made public Wednesday by the National Security Archive, a non-governmental research institute...

"By God, if I had such weapons, I would have used them in the fight against the United States," he told Piro...

In the interviews, Saddam dismissed Osama bin Laden as a "zealot" and said he had never personally met the al-Qaida leader. He said the Iraqi government did not cooperate with the terrorist group against the U.S...

Saddam also stated that the United States used the Sept. 11 terrorist attack as a justification to attack Iraq and said the U.S. had "lost sight of the cause of 9/11." He claimed that he denounced the attack in a series of editorials...

Saddam told him he had "miscalculated" Bush's intentions and expected only a limited U.S. attack. "Hussein stated Iraq could have absorbed another U.S. strike, for he viewed this as less of a threat than exposing themselves to Iran," according to a June 11, 2004, FBI interview report.
From the horse's mouth, so to speak, spoken at a time when he had no further need to dissemble. There are people, including at least one friend of mine, who still believe that Saddam Hussein did have nuclear and biologial WMDs that he successfully hid or moved out of the country, and that our invasion of his country was justified by those weapons.
