Why has international war become more uncommon and unpopular since World War II? Sure some states still meddle in others’ civil wars or launch cyber offensives, but overall the world is experiencing an unprecedented era of peace. Some international relations experts claim that U.S. adventurist foreign policy has held off international war. This week’s guest, Ohio State University political scientist and Cato’s own John Mueller, argues against that premise in his new book The Stupidity of War: American Foreign Policy and the Case for Complacency. He says that after two world wars, most people have realized that there are better solutions to disagreements than international war. Show NotesJohn Mueller bio:https://www.cato.org/people/john-mueller  John Mueller, The Stupidity of War: American Foreign Policy and the Case for Complacency, (Cambridge, UK: Cambridge University Press, 2021).  See acast.com/privacy for privacy and opt-out information.
