John Mueller is a Professor of Political Science at The Ohio State University and a Research Fellow at the Cato Institute. His latest book is called The Stupidity of War: American Foreign Policy and the Case for Complacency. He and Richard discuss how to explain the decline of war, why World War I was a cultural turning point, Hitler as a historical outlier, the Cold War, the war on terror, and the rise of China, among other topics. They also talk about Mueller's article "The Banality of 'Ethnic War'", on what people get wrong about civil wars and mass killing.
