New Books in Diplomatic History

Jeremy Yellen’s The Greater East Asia Co-Prosperity Sphere: When Total Empire Met Total War (Cornell University Press, 2019) is a challenging transnational exploration of the Greater East Asia Co-Prosperity Sphere, Japan’s ambitious, confused, and much maligned attempt to create a new bloc order in East and Southeast Asia during World War II. Yellen’s book is welcome both as the first book-length treatment of the Sphere in English and for also being innovative in both approach and analysis. The book is divided into two parts, each addressing one of the “two Pacific Wars,” as Yellen puts it: a “war of empires” and “an anticolonial war… for independence.” The first half of the book treats the Japanese “high policy” of the Sphere. Here, Yellen not only provides—through the Coprosperity Sphere—a provocative new reading of the Tripartite Pact and the imbrication of Japan’s regional and global geopolitical strategies, but also outlines an important timeline of how Japanese conceptualizations of the Sphere evolved with the changing economic, political, and military expediencies of the Pacific War. Though ideas about the Sphere as a regional order of hierarchical solidarity with Japan at its apex, a “grand strategy of opportunism” rooted in the “sphere-of-influence diplomacy” and “cooperative imperialism” of Japan’s bombastic and enigmatic foreign minister, Matsuoka Yōsuke, Yellen shows that plans for the Sphere only became specific and concrete when Japan’s war situation descended into increasing desperation from 1942 on. The second half of the book shifts gears to examine responses to the Sphere in the Philippines and Burma. Yellen shows that for local nationalist elites like Burma’s first prime minister Ba Maw, whether Japanese rhetoric about the creation of more-or-less liberal international order within the Sphere for the top-echelon nations like Burma and the Philippines was genuine or self-serving, “even sham independence brought opportunity.” By focusing on these pragmatic nationalists (“patriotic collaborators”) Yellen contributes to a growing body of literature on empire that refuses to be pigeonholed by binaries of virtuous resistance and traitorous collaboration.

Catastrophic Diplomacy: US Foreign Disaster Assistance in the American Century (UNC Press, 2023) offers a sweeping history of US foreign disaster assistance, highlighting its centrality to twentieth-century US foreign relations. Spanning over seventy years, from the dawn of the twentieth century to the mid-1970s, it examines how the US government, US military, and their partners in the American voluntary sector responded to major catastrophes around the world. Focusing on US responses to sudden disasters caused by earthquakes, tropical storms, and floods—crises commonly known as "natural disasters"—historian Julia F. Irwin highlights the complex and messy politics of emergency humanitarian relief.
Deftly weaving together diplomatic, environmental, military, and humanitarian histories, Irwin tracks the rise of US disaster aid as a tool of foreign policy, showing how and why the US foreign policy establishment first began contributing aid to survivors of international catastrophes. While the book focuses mainly on bilateral assistance efforts, it also assesses the broader international context in which the US government and its auxiliaries operated, situating their humanitarian responses against the aid efforts of other nations, empires, and international organizations. At its most fundamental level, Catastrophic Diplomacy demonstrates the importance of international disaster assistance—and humanitarian aid more broadly—to US foreign affairs.
Julia F. Irwin, PhD, Yale University, 2009, is professor of history at Louisiana State University. Her research focuses on the place of humanitarian aid in twentieth-century U.S. foreign relations. Her first book, Making the World Safe: The American Red Cross and a Nation’s Humanitarian Awakening (2013), is a history of U.S. international relief efforts during the World War I era; the dissertation on which it is based won the Betty M. Unterberger Dissertation Prize from the Society for Historians of American Foreign Relations.

In October 1943, the Gripsholm—a Swedish ocean liner—and the Teia Maru—a Japanese troop ship—sat in Mormugao, a port in Portuguese India. There, the two ships exchanged their passengers: Allied civilians stuck in Japanese territory after Pearl Harbor , and an assortment of Japanese, Japanese-American, and other Japanese-ethnic people from the Americas.The trade capped a long and fraught diplomatic exchange between the U.S. and Japan, two countries at war. Evelyn Iritani’s book Safe Passage: The Untold Story of Diplomatic Intrigue, Betrayal, and the Exchange of American and Japanese Civilians by Sea During World War II (Farrar, Straus and Giroux, 2026) tells the story of how this exchange came about: How U.S. civilians tried to survive in Japan or occupied Hong Kong, or how the U.S. government pressured Japanese Americans, housed in internment camps, to accept repatriation to Japan, a country many had never known.

Evelyn is a Pulitzer Prize-winning journalist. Her previous book, An Ocean Between Us: The Changing Relationship of Japan and the United States Told in Four Stories From the Life of An American Town (William Morrow and Company: 1994), won a Washington Governor’s Writers Day Award. Evelyn began her career at the Seattle Post-Intelligencer and moved to the Los Angeles Times in 1995 to cover international economics. Her reporting garnered numerous awards, including the 2004 Pulitzer Prize for National Reporting and the George Polk Award for Economics Reporting for a series she co-authored on Wal-Mart.She can be found on her website, Facebook, LinkedIn and Instagram.

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.

Our guests are Felicity Vabulas who is the Blanche E. Seaver Associate Professor of International Studies at Pepperdine University and Professor Inken von Borzyskowski, who is Professor of International Relations at the University of Oxford.

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. You can find Miranda’s interviews on New Books with Miranda Melcher, wherever you get your podcasts.
