Perspectives on International Relations: Power, Institutions, and Ideas shows students new to the field how theories (perspectives) of international affairs—realism, liberalism, constructivism (identity), and critical theory—play a decisive role in explaining every-day debates about world affairs. Why, for example, do politicians and political scientists disagree about the causes of the ongoing conflict in Syria, even though they all have the same facts? Or, why do policymakers disagree about how to deal with North Korea when they are all equally well informed? The new Sixth Edition of this best-seller includes updates on Brexit, the rise of Donald Trump and other populist leaders, and continuing developments for ISIS, Syria, and Russia.

A comprehensive treatment of regional transformation, offering insights from different theoretical perspectives and generating a range of policy-relevant ideas.

A reexamination of America's overloaded foreign policy tradition and its importance for global politics today Debates about U.S. foreign policy have revolved around three main traditions—liberal internationalism, realism, and nationalism. In this book, distinguished political scientist Henry Nau delves deeply into a fourth, overlooked foreign policy tradition that he calls "conservative internationalism." This approach spreads freedom, like liberal internationalism; arms diplomacy, like realism; and preserves national sovereignty, like nationalism. It targets a world of limited government or independent "sister republics," not a world of great power concerts or centralized international institutions. Nau explores conservative internationalism in the foreign policies of Thomas Jefferson, James Polk, Harry Truman, and Ronald Reagan. These presidents did more than any others to expand the arc of freedom using a deft combination of force, diplomacy, and compromise. Since Reagan, presidents have swung back and forth among the main traditions, overreaching under Bush and now retrenching under Obama. Nau demonstrates that conservative internationalism offers an alternative way. It pursues freedom but not everywhere, prioritizing situations that border on existing free countries—Turkey, for example, rather than Iraq. It uses lesser force early to influence negotiations rather than greater force later after negotiations fail. And it reaches timely compromises to cash in military leverage and sustain public support. A groundbreaking revival of a neglected foreign policy tradition, Conservative Internationalism shows how the United States can effectively sustain global leadership while respecting the constraints of public will and material resources.

The United States has never felt at home abroad. The reason for this unease, even after the terrorist attacks of September 11, 2001, is not frequent threats to American security. It is America's identity. The United States, its citizens believe, is a different country, a New World of divided institutions and individualistic markets surviving in an Old World of nationalistic governments and statist economies. In this Old World, the United States finds no comfort and alternately tries to withdraw from it and reform it. America cycles between ambitious internationalist efforts to impose democracy and world order, and more nationalist appeals to trim multilateral commitments and demand that the European and Japanese allies do more. In At Home Abroad, Henry R. Nau explains that America is still unique but no longer so very different. All the industrial great powers in western Europe (and, arguably, also Japan) are now strong liberal democracies. A powerful and peaceful new world exists beyond America's borders and anchors America's identity, easing its discomfort and ending the cycle of withdrawal and reform. Nau draws on constructivist and realist perspectives to show how relative national identities interact with relative national power to define U.S. national interests. He provides fresh insights for U.S. grand strategy toward various countries. In Europe, the identity and power perspective advocates U.S. support for both NATO expansion to consolidate democratic identities in eastern Europe and concurrent, but separate, great-power cooperation with Russia in the United Nations. In Asia, this perspective recommends a shift of U.S. strategy from bilateralism to concentric multilateralism, starting with an emerging democratic security community among the United States, Japan, South Korea, Australia, New Zealand, India, and Taiwan, and progressively widening this community to include reforming ASEAN states and, if it democratizes, China. In the developing world, Nau's approach calls for balancing U.S. moral (identity) and material (power) commitments, avoiding military intervention for purely moral reasons, as in Somalia, but undertaking such intervention when material threats are immediate, as in Afghanistan, or material and moral stakes coincide, as in Kosovo.

The study of international relations, has traditionally been dominated by Western ideas and practices, and marginalized the voice and experiences of the non-Western states and societies. As the world moves to a "post-Western" era, it is imperative that the field of IR acquires a more global meaning and relevance. Drawing together the work of renowned scholar Amitav Acharya and framed by a new introduction and conclusion written for the volume, this book exposes the narrow meaning currently attached to some of the key concepts and ideas in IR, and calls for alternative and broader understandings of them. The need for recasting the discipline has motivated and undergirded Acharya's own scholarship since his entry into the field over three decades ago. This book reflects his own engagement, quarrels and compromise and concludes with suggestions for new pathways to a Global IR- a forward-looking and inclusive enterprise that is reflective of the multiple and global heritage of IR in an changing and interconnected world. It is essential reading for anyone who is concerned about the history, development and future of international relations and international relations theory.

The Oxford Handbook of International Relations offers the most authoritative and comprehensive overview to date of the field of international relations. Arguably the most impressive collection of international relations scholars ever brought together within one volume, the Handbook debates the nature of the field itself, critically engages with the major theories, surveys a wide spectrum of methods, addresses the relationship between scholarship and policy making, and examines the field's relation with cognate disciplines. The Handbook takes as its central themes the interaction between empirical and normative inquiry that permeates all theorizing in the field and the way in which contending approaches have shaped one another. In doing so, the Handbook provides an authoritative and critical introduction to the subject and establishes a sense of the field as a dynamic realm of argument and inquiry. The Oxford Handbook of International Relations will be essential reading for all of those interested in the advanced study of global politics and international affairs.
