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 book brings together a group of leading scholars on international relations to develop and apply the concept of polarity on past and present international relations and discuss its applicability and usefulness in the future. Despite a comprehensive debate on a global power shift, often discussed in terms of the decline of the United States, the crisis in the liberal international order, and the rise of China, IR ́s main concept of power, ‘polarity’, remains undertheorized and understudied. The great powers and their importance for dynamics and processes in the international system are central to current debates on international order, but these debates too often suffer from a combination of politicized empirical analysis and reliance on old theoretical debates and conceptualizations, typically originating in the Cold War security environment. In order to meet these challenges, this book updates, conceptualizes, applies and critically debates the concepts of unipolarity, bipolarity, multipolarity and non-polarity in order to understand the current world order.

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 behaviour applies to the current 'unipolar' setting and, if not, how core theoretical propositions about interstate interactions need to be revised.

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.

Discusses the concept of unipolarity and the political implications of US primacy for the patterns of international politics.

Since the sudden disappearance of the Soviet Union, many scholars have argued that the balance of power theory is losing its relevance. This text examines this viewpoint, as well as looking at systematic factors that may hinder or favour the return of balance of power politics.
