There's an episode of Frontline tonight on PBS, "Truth, War and Consequences", that focuses on the year or so leading up to the invasion in Iraq. It interviews many of the major players in the Bush administration, as well as Iraqi leaders who opposed the invasion.

It should be interesting and insightful, whatever one's current perspective is on the Iraq war.

PBS in my area usually replays the same show late at night also, if you miss it, or want to set your VCR, to record and watch later.
