The Lawfare Podcast: How States Think

It is commonplace for American leaders to describe their fiercest foreign adversaries as irrational, crazy, delusional, or illogical. In their new book, “How States Think: The Rationality of Foreign Policy,” political scientists John Mearsheimer of the University of Chicago and Sebastian Rosato of the University of Notre Dame argue that these claims and many similar ones are often wrong because they're based on a flawed understanding of state rationality in international affairs.

Jack Goldsmith questioned Mearsheimer and Rosato about why they think most states act rationally most of the time in developing grand strategy and managing crises. Among other topics, they discussed how their theory of state rationality differs from rational choice theorists and political psychologists, why understanding state rationality is important to success in international affairs, and why Mearsheimer, a harsh critic of U.S. expansion of NATO and of the U.S. choice to pursue liberal hegemony after the Cold War, nonetheless argues in this book that those decisions were rational.
