Since the collapse of the Soviet Union, the United States has enjoyed unparalleled military power. The international system is therefore unipolar. A quarter of a century later, however, we still possess no theory of unipolarity. Theory of Unipolar Politics provides one. Dr Nuno P. Monteiro answers three of the most important questions about the workings of a unipolar world. Is it durable? Is it peaceful? What is the best grand strategy a unipolar power such as the contemporary United States can implement? In our nuclear world, the power preponderance of the United States is potentially durable but likely to produce frequent conflict. Furthermore, in order to maintain its power preponderance, the United States must remain militarily engaged in the world and accommodate the economic growth of its major competitors, namely, China. This strategy, however, will lead Washington to wage war frequently. In sum, military power preponderance brings significant benefits but is not an unalloyed good.

This volume analyzes the decisions that major powers have made since the Cold War to adapt to a rapidly changing economic and security environment. The authors acknowledge that, while great power wars are now unlikely, positional conflicts over resources and markets still remain.

A comprehensive theory of the causes of nuclear proliferation, alongside an in-depth analysis of sixteen historical cases of nuclear development.

This new book offers a coherent model of a unipolar world order. Unipolarity is usually described either as a ‘brief moment’ or as something historically insignificant. However, we have already seen nearly twenty years of virtual unipolarity and this period has been of great significance for world politics. Two issues have been crucial since the end of the Cold War: How to theorize the distinctiveness and exceptional character of a unipolar international system? And what is it like to conduct state business in a unipolar world? Until now, a comprehensive model for unipolarity has been lacking. This volume provides a theoretical framework for analysis of the current world order and identifies the patterns of outcomes and systematic variations to be expected. Terrorism and attempts by small states to achieve a nuclear capability are not new phenomena or exclusive to the current world order, but in the case of unipolarity these have become attached to the fear of marginalization and the struggle against a powerful centre without the possibility of allying with an alternative superpower. Supplying a coherent theoretical model for unipolarity, which can provide explanations of trends and patterns in the turbulent post-Cold War era, this book will be of interest to students of IR theory, international security and foreign policy.

The end of the Cold War and subsequent dissolution of the Soviet Union resulted in a new unipolar international system that presented fresh challenges to international relations theory. Since the Enlightenment, scholars have speculated that patterns of cooperation and conflict might be systematically related to the manner in which power is distributed among states. Most of what we know about this relationship, however, is based on European experiences between the seventeenth and twentieth centuries, when five or more powerful states dominated international relations, and the latter twentieth century, when two superpowers did so. Building on a highly successful special issue of the leading journal World Politics, this book seeks to determine whether what we think we know about power and patterns of state behavior applies to the current 'unipolar' setting and, if not, how core theoretical propositions about interstate interactions need to be revised.

This is the first book-length treatment of international politics in a unipolar world that adopts a structural realist perspective. It applies Waltz's microeconomic analogy to a market with a price leader. It concludes that unipolarity is sustainable as long as the unipole distributes rewards to other states.

This book discusses the rise of polarity as a key concept in International Relations Theory. Since the end of the Cold War, until at least the end of 2010, there has been a wide consensus shared by American academics, political commentators and policy makers: the world was unipolar and would remain so for some time. By contrast, outside the US, a multipolar interpretation prevailed. This volume explores this contradiction and questions the Neorealist claim that polarity is the central structuring element of the international system. Here, the author analyses different historic eras through a polarity lens, compares the way polarity is used in the French and US public discourses, and through careful examination, reaches the conclusion that polarity terminology as a theoretical concept is highly influenced by the Cold War context in which it emerged. This volume is an important resource for students and researchers with a critical approach to Neorealism, and to those interested in the defining shifts the world went through during the last twenty five years.

This volume brings together leading scholars to analyse the central issues of power, order, and change in world politics.

This edition provides a systematic introduction to the principle theories in international relations. It focuses on the main theoretical traditions - realism, liberalism, international society, and theories of international political economy. It also includes two chapters on social constructivism and foreign policy.

Within the realist school of international relations, a prevailing view holds that the anarchic structure of the international system invariably forces the great powers to seek security at one another's expense, dooming even peaceful nations to an unrelenting struggle for power and dominance. Rational Theory of International Politics offers a more nuanced alternative to this view, one that provides answers to the most fundamental and pressing questions of international relations. Why do states sometimes compete and wage war while at other times they cooperate and pursue peace? Does competition reflect pressures generated by the anarchic international system or rather states' own expansionist goals? Are the United States and China on a collision course to war, or is continued coexistence possible? Is peace in the Middle East even feasible? Charles Glaser puts forward a major new theory of international politics that identifies three kinds of variables that influence a state's strategy: the state's motives, specifically whether it is motivated by security concerns or "greed"; material variables, which determine its military capabilities; and information variables, most importantly what the state knows about its adversary's motives. Rational Theory of International Politics demonstrates that variation in motives can be key to the choice of strategy; that the international environment sometimes favors cooperation over competition; and that information variables can be as important as material variables in determining the strategy a state should choose.
