How States Think

“Thought provoking. . . . Lands its key argument well.”—James Denselow, New York Journal of Books

“A well-written and insightful examination of a central question in international relations. . . . A valuable addition to Mearsheimer’s impressive canon, which is filled with intellectual gems.”—Nayef Al-Rodhan, Montreal Review

“This is a fascinating book . . . and will provide scholars, analysts, and policy makers much food for thought.”—John West, Australian Outlook

“The book’s . . . ambitious reconsideration of rationality . . . promises to enrich future theorizing across paradigms in International Relations.”—Junyang Hu, International Affairs

“How States Think is of interest to anyone looking for a systematic approach to complex strategic and crisis decisions.”—Lagebild Redaktion

“In this argumentative and cogent book, Mearsheimer and Rosato argue that rational strategic action requires a credible theory and a deliberative process.  Examining many important decisions since 1900, they conclude that rational strategic action is normal but not universal.”—Robert O. Keohane, author of After Hegemony

“Mearsheimer and Rosato show why we should not be too quick to dismiss policies we dislike as ‘irrational.’ . . . An impressive, probing, and thought-provoking analysis of a very fundamental issue.”—Marc Trachtenberg, author of The Craft of International History

“John Mearsheimer and Sebastian Rosato demonstrate how great powers jostle relentlessly for national security and expanded power. To base foreign policy on the view that the opponent is irrational is to invite debacles such as the war in Ukraine. To take major actions such as the Iraq War without rational deliberation is to invite disaster. This is a powerful and important essay, calling for foreign policy makers of great powers to undertake rational deliberation and to understand the rational viewpoint of other great powers.”—Jeffrey D. Sachs, University Professor at Columbia University

“How States Think takes dead aim at the tendency to see adversaries and aggressors as inherently ‘irrational.’ Equally important, it argues that familiar conceptions of rationality are unsuitable for analyzing most political decisions. It is a book that no serious international relations scholar will be able to ignore.”—Stephen M. Walt, Robert and Renee Belfer Professor of International Affairs, Harvard Kennedy School

“A lively and provocative book. Mearsheimer and Rosato's message is unflinching: in a world of great uncertainty, the rational leader will need to rely on a worked-out world view to shape state goals and actions—even if history shows that strategic rationality sometimes leads to war, failure, and national self-harm.”—G. John Ikenberry, author of A World Safe for Democracy
