NATO's success in Afghanistan--or lack thereof--will have significant implications for the alliance itself. The authors examine current mission in light of NATO's history and with an eye toward the future. NATO faces a long and daunting list of issues that extends beyond the borders of the member countries. The alliance must confront them, however, because failure to do so would risk its long-term success and sustainability.

The emergence of the European Security and Defense Policy (ESDP) in the last two-thirds of the 1990s and continuing into the new century, has been a complex process intertwining politics, economics, national cultures, and numerous institutions. This book provides an essential background for understanding how security issues as between NATO and the European Union are being posed for the early part of the 21st century, including the new circumstances following the terrorist attacks in New York and Washington on September 11, 2001. This study should be of interest to those interested in the evolution of U.S.-European relations, especially in, but not limited to, the security field; the development of institutional relationships; and key choices that lie ahead in regard to these critical arrangements.

In this new Brookings Marshall Paper, Michael O'Hanlon argues that now is the time for Western nations to negotiate a new security architecture for neutral countries in eastern Europe to stabilize the region and reduce the risks of war with Russia. He believes NATO expansion has gone far enough. The core concept of this new security architecture would be one of permanent neutrality. The countries in question collectively make a broken-up arc, from Europe's far north to its south: Finland and Sweden; Ukraine, Moldova, and Belarus; Georgia, Armenia, and Azerbaijan; and finally Cyprus plus Serbia, as well as possibly several other Balkan states. Discussion on the new framework should begin within NATO, followed by deliberation with the neutral countries themselves, and then formal negotiations with Russia. The new security architecture would require that Russia, like NATO, commit to help uphold the security of Ukraine, Georgia, Moldova, and other states in the region. Russia would have to withdraw its troops from those countries in a verifiable manner; after that, corresponding sanctions on Russia would be lifted. The neutral countries would retain their rights to participate in multilateral security operations on a scale comparable to what has been the case in the past, including even those operations that might be led by NATO. They could think of and describe themselves as Western states (or anything else, for that matter). If the European Union and they so wished in the future, they could join the EU. They would have complete sovereignty and self-determination in every sense of the word. But NATO would decide not to invite them into the alliance as members. Ideally, these nations would endorse and promote this concept themselves as a more practical way to ensure their security than the current situation or any other plausible alternative.

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.

In an ever-changing world marked by geopolitical shifts and evolving security threats, it is crucial to reassess and adapt the collective defense architecture that underpins international stability. Established more than 70 years ago, NATO has been a crucial element of global security and a demonstration of the effectiveness of collective defense. The expansion of NATO's reach has become a significant topic of debate as the world evolves. The North Atlantic Treaty Organization (NATO) has effectively ensured the security of its member states through a collective defense framework, making it a successful alliance. The evolving global landscape, which includes emerging threats, changing power dynamics, and evolving security challenges, has led to a reassessment of NATO's role and scope. There are those who advocate for the acceptance of NATO's expansion as a means of strengthening security and fostering collaboration among nations with similar values. The argument posits that enlarging NATO's membership can function as a deterrent against acts of aggression, strengthen democratic principles, and promote a more stable global system. This special issue, which we had the great pleasure of working together with NATO’s Public Diplomacy Divison, seeks to delve into the multifaceted dimensions of expanding NATO, exploring the challenges and opportunities that lie on the horizon. As we examine this critical issue, it is important to emphasize that the views expressed in these pages are diverse and reflect the complex and varied perspectives on NATO's expansion. Our authors, specialists from a wide-range of different fields, contributed their valuable opinions regarding this important discussion which has become further important since Russia’s aggression against Ukraine has escalated with simultaneously intensifying debates concerning the start of a new Cold-War in our time. Romania's former Prime Minister, Petre Roman, emphasizes the significance of NATO's eastward expansion as a crucial geopolitical process. He highlights how this expansion allowed countries to prepare for potential Russian aggression while pursuing the path of successful democracy. Romania, having emerged from the oppressive communist regime of Ceausescu, eagerly sought NATO membership, and officially joined in 2004. Geographically positioned at the heart of NATO's objectives, Romania plays a central role in the defensive complex within the "post-Soviet space." With Poland guarding the Baltic Sea, Romania stands as a pivotal defender of the Black Sea region, where historical Russian imperial ambitions persist. Moreover, Romania's commitment to NATO is demonstrated through its active participation in Western missions and its role in safeguarding vital corridors, such as the precious grain corridor. This article sheds light on Romania's strong pro-Atlantic and pro-American sentiment, positioning the country as a model ally within the alliance. Professor Richard Higgot and Professor Simon Reich critically examine the prevailing narratives surrounding the structure of the world order, ranging from bi-polarity and multi-polarity to predictions of the end of globalization or a "Cold War v. 2.0." They caution against the tendency of pundits to assert rather than reason these explanations, often seeking fleeting moments of fame. Instead, their paper takes a more modest approach, eschewing grand statements about world order and emphasizing the inherent uncertainty of the future. Their paper offers valuable insights into the nuanced dynamics of a fuzzy bifurcation, emphasizing that the behavior of different actors is influenced by a more fluid and less predictable global landscape. By exploring the implications for NATO, Higgot and Reich contribute to a deeper understanding of the challenges and opportunities that arise in an increasingly complex international environment. Professor Roger E. Kanet undertakes a comprehensive examination of Vladimir Putin's commitment to rebuilding "Greater Russia" and its implications, particularly in the context of the invasion of Ukraine. Putin's vision revolves around re-establishing the former Soviet Union and extending Russian dominance beyond its borders, driven by a belief in the historical and cultural ties between Russians and Ukrainians. Professor Kanet argues that despite other influencing factors, the re-establishment of Moscow's influence and control over as much post-Soviet territory as possible, essentially recreating "Greater Russia," is of utmost importance. While NATO expansion may have been a contributing issue, the author contends that the dominance of Ukraine is a primary objective. Moreover, the successful domination of Ukraine could pave the way for future expansion into other former Soviet areas, such as the Baltics. Professor Ryszard Zieba adopts an offensive realist perspective to examine the implications of NATO's post-Cold War enlargement. The article highlights that these implications unfold on multiple levels, encompassing various aspects of the international landscape. Through this lens, Professor Ryszard Zieba's article offers a comprehensive analysis of the implications of NATO's post-Cold War enlargement. By examining these implications on multiple levels, the article sheds light on the intricate dynamics and challenges that arise in the evolving international landscape. The insights presented contribute to a deeper understanding of the complex interactions between NATO, Russia, and other global actors, urging careful consideration of the consequences of NATO's expansion and its ongoing policy choices.

NATO’s 2010 Strategic Concept officially broadened the alliance’s mission beyond collective defense, reflecting a peaceful Europe and changes in alliance activities. NATO had become an international security facilitator, a crisis-manager even outside Europe, and a liberal democratic club as much as a mutual-defense organization. However, Russia’s re-entry into great power politics has changed NATO’s strategic calculus. Russia’s aggressive annexation of Crimea in 2014 and its ongoing military support for Ukrainian separatists dramatically altered the strategic environment and called into question the liberal European security order. States bordering Russia, many of which are now NATO members, are worried, and the alliance is divided over assessments of Russia’s behavior. Against the backdrop of Russia’s new assertiveness, an international group of scholars examines a broad range of issues in the interest of not only explaining recent alliance developments but also making recommendations about critical choices confronting the NATO allies. While a renewed emphasis on collective defense is clearly a priority, this volume’s contributors caution against an overcorrection, which would leave the alliance too inwardly focused, play into Russia’s hand, and exacerbate regional fault lines always just below the surface at NATO. This volume places rapid-fire events in theoretical perspective and will be useful to foreign policy students, scholars, and practitioners alike.

America needs better options for resolving potential crises In recent years, the Pentagon has elevated its concerns about Russia and China as potential military threats to the United States and its allies. But what issues could provoke actual conflict between the United States and either country? And how could such a conflict be contained before it took the world to the brink of thermonuclear catastrophe, as was feared during the cold war? Defense expert Michael O'Hanlon wrestles with these questions in this insightful book, setting them within the broader context of hegemonic change and today's version of great-power competition. The book examines how a local crisis could escalate into a broader and much more dangerous threat to peace. What if, for example, Russia's “little green men” seized control of a community, like Narva or an even smaller town in Estonia, now a NATO ally? Or, what if China seized one of the uninhabited Senkaku islands now claimed and administered by Japan, or imposed a partial blockade of Taiwan? Such threats are not necessarily imminent, but they are far from inconceivable. Washington could be forced to choose, in these and similar cases, between risking major war to reverse the aggression, and appeasing China or Russia in ways that could jeopardize the broader global order. O'Hanlon argues that the United States needs a better range of options for dealing with such risks to peace. He advocates “integrated deterrence,” which combines military elements with economic warfare. The military components would feature strengthened forward defenses as well as, possibly, limited military options against Russian or Chinese assets in other theaters. Economic warfare would include offensive elements, notably sanctions, as well as measures to ensure the resilience of the United States and allies against possible enemy reprisal. The goal is to deter war through a credible set of responses that are more commensurate than existing policy with the stakes involved in such scenarios.

The end of the Cold War has raised questions about the future of NATO. Now that the threat from the Warsaw Pact has disappeared, there seems little need for a Western military alliance of such magnitude. The contributions here offer various views on NATO's future.

Scholarship on NATO is often preoccupied with key episodes in the development of the organisation and so, for the most part, has remained inattentive to theory. This book addresses that gap in the literature. It provides a comprehensive analysis of NATO through a range of theoretical perspectives that includes realism, liberalism and constructivism, and lesser-known approaches centred on learning, public goods, securitisation and risk. Focusing on NATO’s post-Cold War development, it considers the conceptualisation, purpose and future of the Alliance. This book will be of interest to students and scholars of international organisation, international relations, security and European Politics.

The purpose of NATO: From Regional to Global Security Provider is to provide a comprehensive analysis of the Alliance’s new vision (the new Strategic Concept) and common security impact – associated tasks to be undertaken within a short and longer term time horizon. The book serves as a relevant and timely study of the most pressing issues facing NATO today – including recent lessons gained. It provides recommendations for consideration and further discussion (i.e., the “what” and the “how” regarding future policy options for the North Atlantic Alliance). The intended audience includes international security policy-makers, government officials, elected leaders, academics, interested professionals, civil society and members of the public. Specifically, the book focuses on six topic areas. Part I, the Introduction, relates to conceptual and organizational changes, membership expansion and enlargement. Part II consists of emerging security challenges, including terrorism, piracy, homeland threats, cyber defense and information warfare, energy security, non-proliferation and countering WMD. Part III incorporates national and regional challenges such as the Balkans, Iraq, Afghanistan/Pakistan, the Horn of Africa, North Africa and the Middle East. Part IV deals with military and non-military assets. It integrates capability development, burden sharing, common funding, ballistic missile defenses and the phased adaptive approach, non-strategic nuclear weapons, and a broad-based comprehensive approach to security. Part V covers multifaceted collaborative relationships between NATO and various governmental, inter-governmental, and non-governmental bodies. This section incorporates outreach and engagement with Russia, India, Pakistan, and China, as well as with other non-NATO countries, the Mediterranean Dialogue (MD), and the Istanbul Cooperation Initiative (ICI). Formal and informal linkages with the EU, OSCE, and the UN are also essential features of such a cooperative activity. Additionally, the expanding participation of civil society and growing involvement of new key NATO interlocutors (e.g., NGOs, academics) have created new international partnering opportunities as a means of bolstering global security through innovative public-private partnerships. Part VI includes a Summary and Conclusions.
