Why do states exit international organizations (IOs)? How often does exit from IOs – including voluntary withdrawal and forced suspension – occur? What are the effects of leaving IOs for the exiting state?

Despite the importance of membership in IOs, a broader understanding of exit across states, organizations, and time has been limited. Exit from International Organizations: Costly Negotiation for Institutional Change (Cambridge UP, 2025) addresses these lacunae through a theoretically grounded and empirically systematic study of IO exit. Von Borzyskowski and Vabulas argue that there is a common logic to IO exit, which helps explain both its causes and consequences. By examining IO exit across 198 states, 534 IOs, and over a hundred years of history, they show that exit is driven by states' dissatisfaction, preference divergence, and is a strategy to negotiate institutional change.

The book also demonstrates that exit is costly because it has reputational consequences for leaving states and significantly affects other forms of international cooperation.

NOTE: This book was just awarded the 2026 Chadwick Alger prize for best book in international organizations from the International Studies Association.

In this major new interpretation of Sino-North Korean relations, Dr. Gregg A. Brazinsky argues that neither the PRC nor the DPRK would have survived as socialist states without the ideal of Sino-North Korean friendship. Chinese and North Korean leaders encouraged mutual empathy and sentimental attachments between their citizens and then used these emotions to strengthen popular commitment to socialist state building. Drawing on an array of previously unexamined Chinese and North Korean sources, in Cold War Comrades: An Emotional History of the Sino-North Korean Alliance (Cambridge UP, 2026), Dr. Brazinsky shows how mutual empathy helped to shape political, military, and cultural interactions between the two socialist allies. He explains why the unique relationship that Beijing and Pyongyang forged during the Korean War remained important throughout the Cold War and how it continues to influence the international relations of East Asia today.

This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

Film Diplomacy: A Media History of Turkey-US Relations (Columbia UP, 2026) offers a powerful new account of how film shaped international relations and national identity. Drawing on previously unexamined and recently declassified archives in Turkey and the United States, Ayşehan Jülide Etem demonstrates how both countries used educational films to align institutional agendas and geopolitical interests. By tracing the transnational network of educational cinema, Etem uncovers how film functioned as infrastructure, circulating ideologies, organizing institutions, and training citizens. Moving beyond conventional accounts of propaganda and soft power, this book exposes how film was central to the making of modern Turkey and sheds new light on the media’s role in global politics.

Author Ayşehan Jülide Etem is Assistant Professor of Media Studies at the University of Virginia, where she also directs the Film Studies Concentration. A media studies scholar, Dr. Etem’s research examines how film operates within infrastructures, how it is strategically sponsored, produced, exhibited, and circulated to shape public behavior, manage populations, and mediate power.

The Great Repair: Emotions, Memory, and the German–Jewish Settlement after the Holocaust (Cornell UP, 2026) explores how Jews and Germans began reparations discussions fewer than seven years after the Holocaust—a momentous achievement relegated to the margins of Holocaust scholarship and memory—and the complexities that emerged from the resulting settlement.

Professor Gideon Reuveni illuminates the swift transition and extraordinary chapter in postwar history from the horrors of the Holocaust to a negotiating table where Germans and Jews discussed reparations. Both sides faced the monumental challenge of addressing the injustices of National Socialism through complex deliberations on compensation for collective and individual losses, restitution of property, support for survivors, and formal acknowledgment of Nazi crimes. These negotiations marked a crucial step toward acknowledging historical responsibility and pursuing meaningful redress.

The Great Repair reveals the events, actors, and decisions that led to the signing of the agreement on September 10, 1952, by West Germany, Israel, and the Conference on Jewish Material Claims Against Germany. Ultimately, the enactment of this settlement set a global precedent that genocide cannot go unpunished and moral debts must be paid. It was a historic undertaking of immense scope—unmatched in the history of international relations, just as the extermination of the Jewish people was unprecedented in human history.

From a renowned Yale historian comes a chilling look at the looming threat of the next Great Power war and the urgent interventions necessary to avoid it in the twenty-first century.The vast majority of people alive today have come of age in a world of remarkable stability, presided over by either one or two Superpowers. This is not to say the world has been peaceful; but it has, to a great extent, been predictable. As an increasing number of Great Powers jostle for regional supremacy, as well as competitive advantage in nuclear technology, artificial intelligence, space exploration, and trade, our world has become more fragile, unpredictable—and combustible. The outbreak of global war among today’s Great Powers seems increasingly likely. Such war, as Odd Arne Westad powerfully argues in this urgent book The Coming Storm: Power, Conflict, and Warnings from History (Henry Holt and Co, 2026), would be of a magnitude and devastation never before seen.To understand the threats that face us in this complex new terrain, we must look to the lessons of the past, and especially the late nineteenth and early twentieth century—a time when Great Powers clashed and sought regional dominance, nationalism and populism were on the rise, and many felt that globalization had failed them; a time when tariffs increased, immigration and terrorism were among the biggest issues of the day, and a growing number of people blamed the citizens of other countries for their problems. A time, in other words, that carries eerie parallels with our own.
