This handbook provides a comprehensive survey of the development and importance of the North Atlantic Treaty Organisation (NATO), its role in international relations and its influence on history. The volume examines the Alliance’s evolution in breadth, depth and context by analysing and explaining why and how NATO has endured and remained relevant since its creation. To present an inclusive study of the Alliance’s activities and milestone events and to offer a glimpse of future challenges, the book’s 29 chapters fall into six thematic sections that act as frameworks and allow the exploration of specific topics that pertain to the evolution of NATO: Part I: History of NATO, 1949–2024 Part II: Key Enduring Themes, 1949–2024 Part III: Military Operations, 1995–2024 Part IV: National Perspectives, 1949–2024 Part V: Regional Perspectives, 1949–2024 Part VI: Future Prospects, 2024– This handbook will be of much interest to students and researchers of NATO, strategic studies, defence studies and International Relations, as well as for staff and fellows at security- and defence-oriented think tanks and government officials, military personnel and other practitioners in the areas of foreign affairs and defence.

This new Handbook provides readers with the tools to understand the evolution of transatlantic security from the Cold War era to the early 21st century. After World War II, the US retained a strong presence as the dominant member of NATO throughout the Cold War. Former enemies, such as Germany, became close allies, while even countries that often criticized the United States made no serious attempt to break with Washington. This pattern of security co-operation continued after the end of the Cold War, with NATO expansion eastwards extending US influence. Despite the Iraq war prompting a seemingly irreparable transatlantic confrontation, the last years of the Bush administration witnessed a warming of US-European relations, expected to continue with the Obama administration. The contributors address the following key questions arising from the history of transatlantic security relations: What lies behind the growing and continuing European dependency on security policy on the United States and what are the political consequences of this? Is this dependency likely to continue or will an independent European Common Foreign and Security Policy eventually emerge? What has been the impact of 'out-of-area' issues on transatlantic security cooperation? The essays in this Handbook cover a broad range of historical and contemporary themes, including the founding of NATO; the impact of the Korean War; the role of nuclear (non-)proliferation; perspectives of individual countries (especially France and Germany); the impact of culture, identity and representation in shaping post-Cold War transatlantic relations; institutional issues, particularly EU-NATO relations; the Middle East; and the legacy of the Cold War, notably tensions with Russia. This Handbook will be of much interest to students of transatlantic security, NATO, Cold War Studies, foreign policy and IR in general.
