When NATO was founded in 1949, it had a clearly defined role. The demise of the Cold War, the disintegration of the Soviet Union and the collapse of communism in the period from 1989 to 1991 called into question NATO’s future role and its continued existence. The primary role was called into question over its future relevance in the post-Cold War world. The reason for NATO was essentially a military alliance to deter Soviet and Warsaw Pact aggression – however, once the threat had finished its role had been challenged by many academics and governments. Many analysts felt that NATO was nothing more than an out of date alliance from the Cold War with no real future. Others would say, however, that an organisation such as NATO was still crucial in the modern world to ensure that countries do not act unilaterally, but co-operate with allies. In view of the situations, NATO has managed to address new issues and adapt its roles on different levels.

The concept of environmental security was introduced in an attempt to expand this conceptualization of security by suggesting that human-induced environmental degradation and demographic pressures are new emerging security problems at the national and international levels. The argument for an environmental security perspective arose from three key observations: environmental threats can have catastrophic outcomes, traditional security thinking does not prepare society to deal with these threats, and, unlike traditional security issues, environmental threats are not confined by national boundaries. The United Nations Environment Programme (UNEP), states that, “Over the last 60 years, at least 40 percent of all internal conflicts have been linked to the exploitation of natural resources”. In addition, “More than two billion people have been affected by disasters and conflicts since 2000”. Common examples of these new threats are climate change and sea level rise, ozone depletion, deforestation, land degradation; over fishing, fresh water scarcity, and increased spread of infectious diseases.

This open access volume surveys the state of the field to examine whether a fifth wave of deterrence theory is emerging. Bringing together insights from world-leading experts from three continents, the volume identifies the most pressing strategic challenges, frames theoretical concepts, and describes new strategies. The use and utility of deterrence in today’s strategic environment is a topic of paramount concern to scholars, strategists and policymakers. Ours is a period of considerable strategic turbulence, which in recent years has featured a renewed emphasis on nuclear weapons used in defence postures across different theatres; a dramatic growth in the scale of military cyber capabilities and the frequency with which these are used; and rapid technological progress including the proliferation of long-range strike and unmanned systems. These military-strategic developments occur in a polarized international system, where cooperation between leading powers on arms control regimes is breaking down, states widely make use of hybrid conflict strategies, and the number of internationalized intrastate proxy conflicts has quintupled over the past two decades. Contemporary conflict actors exploit a wider gamut of coercive instruments, which they apply across a wider range of domains. The prevalence of multi-domain coercion across but also beyond traditional dimensions of armed conflict raises an important question: what does effective deterrence look like in the 21st century? Answering that question requires a re-appraisal of key theoretical concepts and dominant strategies of Western and non-Western actors in order to assess how they hold up in today’s world.

This timely volume assesses NATO's current accomplishments, continuing challenges, and potential pitfalls. Leading international scholars and policymakers explore three key themes influencing NATO's future: transatlantic relations, the debate over enlargement, and the organization's new functions. Weighing the fate of an alliance poised for renewal or decline, the contributors offer informed analysis and discussion of an organization that has changed profoundly over the past five years and continues to evolve in the face of an uncertain global environment.

Following the end of the Second World War, the creation of regional organizations in Europe provided niche functions to help ensure regional stability through security and transition. Yet, as the Cold War ended and the Soviet Union dissolved, each of these organizations evolved to have a post-Cold War role in the region. Since then, the level of convergence of norms, interests and objectives between these main regional organizations has increased considerably. Is there a common agenda in Europe? Does Europe still need so many organizational elements to tackle the major challenges? This book examines the way the EU, NATO, OSCE, and Council of Europe relate to and interact with each other, identifying the areas of positive convergence and divergence as well as areas of negative cooperation and conflict. By tracing the institutional development and regional integration in Europe, the book questions to what degree do European organizations maintain separate identities and most importantly do these organizations still offer a unique and useful service to regional stability. In developing this argument, policy areas analysed include: "

The key role in the security policy of the North Atlantic Treaty Organization (NATO) is to prevent new types of asymmetric challenges and deal with the new architecture of the Euro-Atlantic security environment, including the control of weapons of mass destruction. In modern international politics, the growing militaristic policies of the states have created many dangers and raised the need for NATO to address new issues that the Alliance did not face during the Cold War. NATO and the Future of European and Asian Security reflects on difficult geopolitical and geostrategic conditions and reviews how new types of warfare have a drastic impact on NATO’s military and defense doctrine. This book provides the newest data and theories and contributes to the understanding of the transformation of the regional security environment in the aegis of the Euro-Atlantic. Covering topics including foreign policy, global security, hybrid warfare, securitization, and smart defense, this book is essential for government officials, policymakers, public relations officers, military and defense agencies, teachers, historians, political scientists, security analysts, national security professionals, administrators, government organizations, researchers, academicians, and students.
