The long running and respected series by PBS, Frontline, pulls together their past coverage of middle east conflicts and US policies to present a chronology of the events leading up to the Iraq war. It's extremely well done and informative of the complex nature of the conflict and the US stance towards Saddam Hussein.
This video was created from VHS but is of high quality. The video is only available to educational outlets.
