In the United States, World War II is often regarded as a time of unrivaled national unity and optimism. In reality, however, this traumatic period tested the American resolve in the most significant way since the Civil War. How did the nation rise to the occasion? Author and historian Tracy Campbell examines the critical year of 1942. Campbell is the E. Vernon Smith and Eloise C. Smith professor of American history in the University of Kentucky's College of Arts & Sciences. The program is "History With David Rubenstein."
