John J. Mearsheimer is the R. Wendell Harrison Distinguished Service Professor of Political Science and the co-director of the Program on International Security Policy at the University of Chicago. His books include The Tragedy of Great Power Politics, which won the Joseph Lepgold Book Prize, and New York Times bestseller The Israel Lobby and U.S. Foreign Policy, which has been translated into twenty-one languages.

In Why Leaders Lie, Mearsheimer provides the first systematic analysis of lying as a tool of statecraft, identifying the varieties, the reasons, and the potential costs and benefits. Drawing on a wealth of examples, he argues that leaders often lie for good strategic reasons, so a blanket condemnation is unrealistic and unwise. Perhaps no distinction is more important than that between lying to another state and lying to one's own people. There has never been a sharp analysis of international lying. Now a leading expert provides a richly informed and powerfully argued work that will change our understanding of why leaders lie.
