How frequent is lying in international politics? Which types of leaders lie the most, and to whom do leaders most frequently lie: other states, or their own people? Is all deception lying, or should we think of lying as distinct from other sorts of subterfuge, like spinning and concealment? Moreover, is lying a useful tool of statecraft? What happens when lying goes wrong? Best‐selling author and leading international relations scholar John Mearsheimer takes on these questions in his new book, Why Leaders Lie: The Truth about Lying in International Politics. Please join the author and two discussants for an examination of this fascinating and under‐studied topic.
