The Unknown Known

Errol Morris offers a mesmerizing portrait of Donald Rumsfeld, one of the key architects of the Iraq War. Although Rumsfeld has held lofty positions of American political power for half a century, most people know little about him. When Rumsfeld wrote, as part of his most famous meditation, that an "unknown known" refers to "things you think you know that it turns out you do not," he could have been speaking about himself. The Unknown Known is not intended as yet another postmortem on the Iraq War, but rather an illumination of a mystery.
