New Books in Diplomatic History

How has the United Nations shaped the management of the Arab-Israeli conflict, and what can its history of peacekeeping teach us about the challenges facing the Middle East today? In this episode of International Horizons, Eli Karetny speaks with Diego Salama, Research Associate at Leiden University’s Institute of Security and Global Affairs, about his new book, The UN’s Multi-Dimensional Approach to the Israel-Arab Conflict, 1967–1982: An Architecture for Peace (Routledge, 2026).
Drawing on previously classified UN archival material, Salama examines how four UN operations developed into an interconnected regional peacekeeping system, highlighting their operational achievements, institutional limitations, and capacity for innovation. The conversation explores the UN’s role in the negotiations following the 1973 Yom Kippur War, the challenges posed by the aftermath of October 7, and the growing crisis of confidence in multilateralism. Salama argues that the UN’s institutional memory, established relationships, and operational experience remain essential assets for addressing the region’s future, even as its structures require reform and renewed strategic direction.

Have you ever had one of those days when you’ve had to explain to a leading Senator that the woman approaching his table is actually a Soviet spy hoping to bed and blackmail him? Well, Danny Grossman has.
As a twenty-six-year-old diplomat serving in Leningrad during the Cold War, Grossman’s phones were tapped, his home was bugged, his neighbor went out the window, his houseguest was attacked, his consulate was rocked by something called Chernobyl, his movements were tracked by an ambitious young KGB officer named Vladimir Putin—and that was only the beginning!
With autocracy rising around the world, Grossman has written a stunning meditation on the politics of oppression, the nature of dreamers, and the resilience of ordinary people under siege.

Constructing a Renaissance Pope: Rhetoric, Ceremony, and Authority in the Age of Leo X (1513-1521) (Oxford University Press, 2026) by Dr. Elizabeth McCahill examines the rhetoric and ceremony of the papal court during the pontificate of Pope Leo X (1513-1521).
The son of Lorenzo de' Medici, Leo has been celebrated for bringing a Golden Age of cultural efflorescence to Renaissance Rome, but he has also been excoriated for the prodigality, nepotism, and corruption that provoked Martin Luther first to criticize and then to split from the church. This study does not focus on Leo as a historical individual but analyses the collaborative efforts of curial officials, humanists, and ceremonial experts to construct his image. Although personal loyalty and private self-interest motivated these bureaucrats and scholars, so too did commitment to a traditional vision of papal authority, a vision facing new challenges in an era of rapid spiritual, social, and political change.
Weaving together material from the diaries and manuals of Paris de' Grassi, the papal Master of Ceremonies, and a variety of letters, orations, and other humanist texts, the book situates papal image-making techniques within the broader context of Renaissance culture. It argues that the scripted rites and Ciceronian rhetoric on which the papal court spent so much time and money served as tools of persuasion, creating a rarefied arena in which power, hierarchy, and tradition were continually enacted and negotiated. By embedding curial activities within the geopolitical and cultural landscape of early sixteenth-century Europe, the book illuminates the tension between the mystique of traditional authority and the new technologies, political norms, and religious dissent that conspired to destabilize the papal role.

The War on Terror remained an enduring feature of American foreign policy for over two decades. The War on Terror(Agenda Publishing, 2025), by Professors Andrew Thomson and Rubrick Biegon, positions the War on Terror within the broader context of Cold War interventionism and the rise of various transnational threats to American (and global) security during the late twentieth century. It introduces readers to the main concepts, debates and theories which have been used to understand and make sense of the War on Terror. These include approaches that frame it as a disparate set of policies aimed at reducing the risk of terrorist attacks against American citizens at both home and aboard; as part of a project aimed at helping maintain the United States' dominant position within international politics; and as an idea intimately bound up with perceptions of American national identity and America's place in the world. In this way, the book aims to show how the War on Terror has changed global politics, as well as why it has been fought and proven so difficult to end despite multiple failed attempts at course correction. The book, published in 2025 and now available from University of Edinburgh Press, is ideally suited for courses on international security, American foreign policy and contemporary world politics.
Rubrick Biegon is Lecturer in International Relations at the University of Kent. Co-author Andrew Thomson, reader in peace and conflict studies at Queens University Belfast, joined historian and U.S. army veteran Jacob Hagstrom in a discussion about the book's major themes, sources, and theoretical underpinnings.
Jacob Hagstrom is a military historian and author of America's Favorite Warlord (Pen and Sword, 2026)

Romania, the Little Entente and the Struggle for Europe (Bloomsbury, 2026) is the first in-depth, English-language study of Romania's role in the Little Entente-an alliance formed with Czechoslovakia and Yugoslavia to defend the territorial status quo in Central and Eastern Europe after the First World War. While this alliance has often been dismissed in international historiography as peripheral, this book argues that the Little Entente was a critical, albeit fragile, experiment in regional security and interwar diplomacy. Anchored in Romania's foreign policy, it reinterprets the alliance as a revealing case study in small-state agency, collective security, and the entropic pressures of the post-war order. Whilst drawing on a wide range of Romanian diplomatic archives, press materials, and memoirs, many of which remain underutilized in anglophone scholarship, Grey also situates Romania's actions within the larger European context, assessing how regional alliances engaged with the League of Nations and evolving relationships with France, Germany, Italy, and Soviet Russia. Romania, the Little Entente and the Struggle for Europe moves beyond simplistic narratives of failure and instead presents a nuanced portrait of the Little Entente as a fragile, flawed, but earnest effort to secure peace in a precarious international order-one whose lessons resonate powerfully today.
