I had meant to post a reminder (see the comments) before it aired on PBS on April 14, but the documentary Worse than War, based on Danile Goldagen's book Worse Than War: Genocide, Eliminationism, and the Ongoing Assault on Humanity, can now be viewed at the link.
As usual for PBS, the site itself is a useful resource. For example, I recommend reading this excerpt from the book explaining the concept of "eliminationism."
