Many people think the American Civil War had to happen. It reunited a torn country and put an end to slavery. But was it a "good" war, and is there even such a thing? Host Frank Stasio talks about the morality of the Civil War with David Goldfield, the Robert Lee Bailey Professor of History at the University of North Carolina at Charlotte and author of “America Aflame: How the Civil War Created a Nation” (Bloomsbury Press/2011); and Fitzhugh Brundage, the William Umstead Distinguished Professor of History at the University of North Carolina at Chapel Hill.
