How do states advance their national security interests? Conventional wisdom holds that states must court the risk of catastrophic war by “tying their hands” to credibly protect their interests. Dan Reiter overturns this perspective with the compelling argument that states craft flexible foreign policies to avoid unwanted wars. Through a comprehensive analysis of key international crises, including the Berlin, Taiwan Straits, and Cuban Missile Crises, and the Korean and Vietnam Wars, Reiter provides new perspectives on the causes of wars, the role of international alliances, foreign troop deployments, leader madness, and the impact of AI on international relations. With critical insights into contemporary foreign policy challenges, such as America’s role in NATO, the risks of war with China, containing a resurgent Russia, and the dangers of nuclear war, Untied Hands: How States Avoid the Wrong Wars (Cambridge University Press, 2025) is essential reading for anyone interested in understanding how states can effectively manage international crises while avoiding the wrong wars.

Dan Reiter is Samuel Candler Dobbs Professor of Political Science at Emory University.

Leo Bader is a senior at Wesleyan University studying political theory and history.
