Realism and International Politics brings together the collected essays of Kenneth N. Waltz, one of the most important and influential thinkers of international relations in the second half of the twentieth century. His books Man, the State and War and Theory of International Politics are classics of international relations theory and gave birth to the school of thought known as neo-realism or structural realism, out of which many of the current crop of realist scholars and thinkers has emerged. Waltz frames these seminal pieces in his theoretical development by explaining the context in which they were written and, building on the broader aims of these theories, explains the elusive nature of power balancing in today's international system. It is an essential volume for both students and scholars.

1. The realist tradition

Stefano Guzzini's study offers an understanding of the evolution of the realist tradition within International Relations and International Political Economy. It sees the realist tradition not as a school of thought with a static set of fixed principles, but as a repeatedly failed attempt to turn the rules of European diplomacy into the laws of a US social science. Realism in International Relations and International Political Economy concentrates on the evolution of a leading school of thought, its critiques and its institutional environment. As such it will provide an invaluable basis to anyone studying international relations theory.

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.

This book contributes to the rethinking of realism through multiple analyses of the keys works of Kenneth Waltz, arguing that a sophisticated appreciation of realism is needed to truly understand world politics and International Relations. Bringing together a theoretically varied group of leading scholars from both sides of the Atlantic, this book is an outstanding appreciation of the work of realismâe(tm)s most important theorist since the Second World War, and the persistent themes thrown up by his work over a half-century. The contributors do not engage with Waltzâe(tm)s work as slavish disciples, but rather as positive critics, recognising its decisive significance in International Relations, while using the process of critical engagement to search for new or renewed understandings of unfolding global situations and new insights into long-standing problems of theory-building. The book will be of great interest to students of IR, foreign policy, security studies and politics.

Critical and scientific realism have emerged as important perspectives on international relations in recent years. The attraction of these approaches lies in the claim that they can transcend the positivism vs postpositivism divide. This book demonstrates the vitality of this approach and the difference that 'realism' makes.

This book examines the fascinating story of how the chief architects of realism (Hans Morgenthau, Kenneth Waltz and John Mearsheimer) dealt with some of the most pressing political issues of our time through the lenses of fear. Pashakhanlou conducts the most comprehensive evaluation of their works to date, compromising of a meticulous analysis of 400 of their publications. As such, this book is an invaluable resource for practitioners, students and concerned citizens that seek to understand how three of the most influential International Relations scholars thought about the implications of fear at the global level. ‘In this important book, the author gets to the heart of the underlying emotional condition on which so much rational political thought in International Relations is built. By uncovering the role of fear within the modern classics of realism, the book sheds light on the role that fear plays in producing otherwise rational decision-making.’ David Galbreath, Professor of International Security, University of Bath, UK ‘The role played by fear in Realist international theory is under-explored and poorly theorised. This book addresses this lacuna and provides a thorough and systematic analysis of the significance of fear in Realism. In doing so, Arash Heydarian Pashakhanlou makes a major contribution to International Relations theory, and the ‘emotional turn’ in the study of contemporary international politics’.
