How does a democracy decide to wage war? On the 66th anniversary of the attack on Pearl Harbor by Japanese warplanes, David Brancaccio interviews filmmakers Ken Burns and Lynn Novick and Rev. James Forbes Jr. about Burns and Novick's epic World War II documentary THE WAR. Looking to the past as a mirror to the present, the four discuss how the waging of war intersects with our notion of democracy.

"It's incumbent upon a democratic society to evaluate what the arithmetic is - the cost of war," Burns tells the group.
