The North Atlantic Treaty Organization (NATO) is the world’s largest, most powerful military alliance. The Alliance has navigated and survived the Cold War, the collapse of the Soviet Union, and the post-9/11 era. Since the release of the 2010 Strategic Concept, NATO’s strategic environment has again undergone significant change. The need to adapt is clear. An opportunity to assess the Alliance’s achievements and future goals has now emerged with the Secretary General’s drive to create a new Strategic Concept for the next decade—an initiative dubbed NATO 2030. A necessary step for formulating a new strategic outlook will thus be understanding the future that faces NATO. To remain relevant and adjust to new circumstances, the Alliance must identify its main challenges and opportunities in the next ten years and beyond. This book contributes to critical conversations on NATO’s future vitality by examining the Alliance’s most salient issues and by offering recommendations to ensure its effectiveness moving forward. Written by a diverse, multigenerational group of policymakers and academics from across Europe and the United States, this book provides new insights about NATO’s changing threat landscape, its shifting internal dynamics, and the evolution of warfare. The volume’s authors tackle a wide range of issues, including the challenges of Russia and China, democratic backsliding, burden sharing, the extension of warfare to space and cyberspace, partnerships, and public opinion. With rigorous assessments of NATO’s challenges and opportunities, each chapter provides concrete recommendations for the Alliance to chart a path for the future. As such, this book is an indispensable resource for NATO’s strategic planners and security and defense experts more broadly.

The creation of the North Atlantic Treaty Organization was one of the most important accomplishments of American diplomacy in countering the Soviet threat during the early days of the Cold War. Why and how such a reversal of a 150-year nonalignment policy by the United States was brought about, and how the goals of the treaty became a reality, are questions addressed here by a leading scholar of NATO. The importance of restoring Europe to strength and stability in the post-World War II years was as obvious to America as to its allies, but the means of achieving that goal were far from clear. The problem for European statesmen was how to secure much- needed American economic and military aid without sacrificing political independence. For American policymakers, in contrast, a degree of American control was seen as an essential quid pro quo. As Mr. Kaplan shows, the lengthy negotiations of 1947 and 1948 were chiefly concerned with reconciling these opposing views. For the Truman administration, the difficulties of achieving a treaty acceptable to the allies were matched by those of winning its acceptance by Congress and the public. Many Americans saw such an "entangling alliance" as a threat not only to American security but to the viability of the United Nations. Mr. Kaplan demonstrates the tortuous course of the debate on the treaty and the pivotal role of the communist invasion of South Korea in its ultimate approval. This authoritative study offers a timely reevaluation of the origins of an alliance that continues to play a critical role in the balance of power and in the prospects for world peace.

This book takes a new approach to answering the question of how NATO survived after the Cold War by examining its complex relationship with the United States. A closer look at major NATO engagements in the post-Cold War era, including in the Balkans, Afghanistan, Iraq, and Libya, reveals how the US helped comprehensively reshape the alliance. In every conflict, there was tension between the United States and its allies over mission leadership, political support, legal precedents, military capabilities, and financial contributions. The author explores why allied actions resulted in both praise and criticism of NATO’s contributions from American policymakers, and why despite all of this and the growing concern over the alliance’s perceived shortcomings the United States continued to support the alliance. In addition to demonstrating the American influence on the alliance, this works demonstrates why NATO’s survival is beneficial to US interests.

Sayle's book is a remarkably well-documented history of the NATO alliance. This is a worthwhile addition to the growing literature on NATO and a foundation for understanding its current challenges and prospects.― Choice Born from necessity, the North Atlantic Treaty Organization (NATO) has always seemed on the verge of collapse. Even now, some seventy years after its inception, some consider its foundation uncertain and its structure weak. At this moment of incipient strategic crisis, Timothy A. Sayle offers a sweeping history of the most critical alliance in the post-World War II era. In Enduring Alliance, Sayle recounts how the western European powers, along with the United States and Canada, developed a treaty to prevent encroachments by the Soviet Union and to serve as a first defense in any future military conflict. As the growing and unruly hodgepodge of countries, councils, commands, and committees inflated NATO during the Cold War, Sayle shows that the work of executive leaders, high-level diplomats, and institutional functionaries within NATO kept the alliance alive and strong in the face of changing administrations, various crises, and the flux of geopolitical maneuverings. Resilience and flexibility have been the true hallmarks of NATO. As Enduring Alliance deftly shows, the history of NATO is organized around the balance of power, preponderant military forces, and plans for nuclear war. But it is also the history riven by generational change, the introduction of new approaches to conceiving international affairs, and the difficulty of diplomacy for democracies. As NATO celebrates its seventieth anniversary, the alliance once again faces challenges to its very existence even as it maintains its place firmly at the center of western hemisphere and global affairs.

Despite momentous change, NATO remains a crucial safeguard of security and peace. Today’s North Atlantic Treaty Organization, with nearly thirty members and a global reach, differs strikingly from the alliance of twelve created in 1949 to “keep the Americans in, the Russians out, and the Germans down.” These differences are not simply the result of the Cold War’s end, 9/11, or recent twenty-first-century developments but represent a more general pattern of adaptability first seen in the incorporation of Germany as a full member of the alliance in the early 1950s. Unlike other enduring post–World War II institutions that continue to reflect the international politics of their founding era, NATO stands out for the boldness and frequency of its transformations over the past seventy years. In this compelling book, Seth A. Johnston presents readers with a detailed examination of how NATO adapts. Nearly every aspect of NATO—including its missions, functional scope, size, and membership—is profoundly different than at the organization’s founding. Using a theoretical framework of “critical junctures” to explain changes in NATO’s organization and strategy throughout its history, Johnston argues that the alliance’s own bureaucratic actors played important and often overlooked roles in these adaptations. Touching on renewed confrontation between Russia and the West, which has reignited the debate about NATO’s relevance, as well as a quarter century of post–Cold War rapprochement and more than a decade of expeditionary effort in Afghanistan, How NATO Adapts explores how crises from Ukraine to Syria have again made NATO’s capacity for adaptation a defining aspect of European and international security. Students, scholars, and policy practitioners will find this a useful resource for understanding NATO, transatlantic relations, and security in Europe and North America, as well as theories about change in international institutions.

For much of the last 25 years, NATO has focused on crisis managementin places such as Kosovo and Afghanistan,resulting in major changes to alliance strategy, resourcing,force structure, and training. Re-embracing collective defense —which lies at the heart of the Treaty of Washington’s Article 5 commitment— is no easy feat, and not something NATO can do through rhetoric and official pronouncements. Nonetheless,this shift is vitally necessary if the alliance is to remain the bulwark of Western defense and security. Russia’s illegal annexation of Crimea and its invasion of Ukraine have fundamentally upended the security environment in Europe, thrusting NATO into the spotlight as the primary collective defense tool most European states rely upon to ensure their security. Collective defense is one of the alliance’s threecore missions, along with crisis management and cooperative security. It is defined in Article 5, the most well-known and arguably most important part of NATO’s founding treaty, which states: “The Parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all.” Although all three missions are vital to the interests of NATO’s many member states, collective defense has become first among equals once again. However,three very significant hurdles stand in the way of the alliance and its member states as they attempt to re-embrace collective defense. These loosely correspond to an ends-waysmeans construct. First is the alliance's strategy toward Russia. Is Russia an adversary,a partner,neither,or both? How should strategy and policies change to place the alliance and its members on more solid ground when it comes to managing Russia? Second are the ongoing disputes over resourcing and burden-sharing. In recent years, it has become commonplace for American leaders to publicly berate European allies in an effort to garner more contributions to the common defense. How might the alliance better measure and more equitably share security burdens? Third is the alliance’s readiness to fulfill its objectives. Many allies have announced or are implementing increases in defense spending. However, governments of European NATO member states are strongly incentivized by domestic politics to favor acquisition of military hardware or spending on personnel salaries and benefits,usually at the expense of readiness. The result is that NATO military forces risk quickly becoming hollow in a way that is often underappreciated, which will prevent the alliance from fulfilling the collective defense promise inherent in Article 5. The book examines all such questions to assess NATO’s return to collective defense and offer a roadmap for overcoming those challenges in both the short and long-term.
