The essays in this book cover a fast-paced 150 years of Vatican diplomacy, starting from the fall of the Papal States in 1870 to the present day. They trace the transformation of the Vatican from a state like any other to an entity uniquely providing spiritual and moral sustenance in world affairs. In particular, the book details the Holy See’s use of neutrality as a tool and the principal statecraft in its diplomatic portmanteau. This concept of “permanent neutrality,” as codified in the Lateran Treaties of 1929, is a central concept adding to the Vatican's uniqueness and, as a result, the analysis of its policies does not easily fit within standard international relations or foreign policy scholarship. These essays consider in detail the Vatican’s history with “permanent neutrality” and its application in diplomacy toward delicate situations as, for instance, vis a vis Fascist Italy, Nazi Germany, and Imperial Japan, but also in the international relations of the Cold War in debates about nuclear non-proliferation, or outreach toward the third world, including Cuba and Venezuela. The book also considers the ineluctable tension between pastoral teachings and realpolitik, as the church faces a reckoning with its history.

This collection examines the theory, practice, and application of state neutrality in international relations. With a focus on its modern-day applications, the studies in this volume analyze the global implications of permanent neutrality for Taiwan, Russia, Ukraine, the European Union, and the United States. Exploring permanent neutrality’s role as a realist security model capable of rivaling collective security, the authors argue that permanent neutrality has the potential to decrease major security dilemmas on the global stage.

This revised and expanded edition of the Research Handbook on International Law and Cyberspace brings together leading scholars and practitioners to examine how international legal rules, concepts and principles apply to cyberspace and the activities occurring within it. In doing so, contributors highlight the difficulties in applying international law to cyberspace, assess the regulatory efficacy of these rules and, where necessary, suggest adjustments and revisions.

Lottaz, Iwama, and their contributors investigate the role of neutral and nonaligned European states during the negotiations for the Treaty on the Nonproliferation of Nuclear Weapons (NPT). Focusing on the years from the Irish Resolution of 1958 until the treaty’s opening for signatures ten years later, the nine chapters written by area experts highlight the processes and reasons for the political and diplomatic actions the neutrals took, and how those impacted the multilateral treaty negotiations. The book reveals new aspects of the dynamics that lead to this most consequential multilateral breakthrough of the Cold War. In part one, three chapters analyze the international system from a bird’s eye perspective, discussing neutrality, nonalignment, and the nuclear order. The second part features six detailed case studies on the politics and diplomacy of Ireland, Sweden, Finland, Switzerland, Austria, and Yugoslavia. Overall, this study suggests that despite the volatile and dangerous nature of the early Cold War, the balance of the strategic environment enabled actors that were not part of one or the other alliance system to play a role in the interlocking global politics that finally created the nuclear regime that defines international relations until today. A valuable resource for scholars of nonproliferation, the Cold War, neutrality, nonalignment, and area studies.

In 2020, the Vatican opened its archives for the pontificate of Pius XII (1939-1958), the pope that led the Catholic Church during WWII, the Holocaust, and the beginning of the Cold War. The Global Pontificate of Pius XII brings together historians who were among the first to consult the previously unseen Vatican materials. These long-awaited records allow for an expansion of the current historiography beyond the pope’s biography. Methodologically, the volume works to transcend the rigidity of religious history and engage with new approaches in global, transnational, and postcolonial history to re-introduce questions surrounding religion into modern post-war historiography.
