Foreign policy motivation is a complex mix reflecting the fears and aspirations of publics, interest groups, bureaucratic sets, and important individuals. International conflict cannot be resolved without resolving how foreign policy is motivated. This book presents a conceptual framework for identifying and weighing foreign policy motives that shape, direct, and alter foreign policy.

The Diffusion of Military Power examines how the financial and organizational challenges of adopting new methods of fighting wars can influence the international balance of power. Michael Horowitz argues that a state or actor wishing to adopt a military innovation must possess both the financial resources to buy or build the technology and the internal organizational capacity to accommodate any necessary changes in recruiting, training, or operations. How countries react to new innovations--and to other actors that do or don't adopt them--has profound implications for the global order and the likelihood of war.

Horowitz looks at some of the most important military innovations throughout history, including the advent of the all-big-gun steel battleship, the development of aircraft carriers and nuclear weapons, and the use of suicide terror by nonstate actors. He shows how expensive innovations can favor wealthier, more powerful countries, but also how those same states often stumble when facing organizationally complicated innovations. Innovations requiring major upheavals in doctrine and organization can disadvantage the wealthiest states due to their bureaucratic inflexibility and weight the balance of power toward smaller and more nimble actors, making conflict more likely. This book provides vital insights into military innovations and their impact on U.S. foreign policy, warfare, and the distribution of power in the international system.

Zahariadis offers a theory that explains policymaking when "ambiguity" is present -- a state in which there are many ways, often irreconcilable, of thinking about an issue. Expanding and extending John Kingdon's influential "multiple streams" model that explains agenda setting, Zahariadis argues that manipulation, the bending of ideas, process, and beliefs to get what you want out of the policy process, is the key to understanding the dynamics of policymaking in conditions of ambiguity. He takes one of the major theories of public policy to the next step in three different ways: he extends it to a different form of government (parliamentary democracies, where Kingdon looked only at what he called the United States's presidential "organized anarchy" form of government); he examines the entire policy formation process, not just agenda setting; and he applies it to foreign as well as domestic policy. This book combines theory with cases to illuminate policymaking in a variety of modern democracies. The cases cover economic policymaking in Britain, France, and Germany, foreign policymaking in Greece, all compared to the U.S. (where the model was first developed), and an innovative computer simulation of the policy process.

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 iconoclastic and fundamental work, Eric Nordlinger's last, advocates a new variant of isolationism, a "national strategy" confining U.S. military actions largely to North America and to neighboring sea-and air- lanes but encouraging international activism and engagement in nonsecurity realms. In Nordlinger's view, disengaging from security commitments on distant shores would liberate the United States to use its resources and decision-making powers to act more effectively abroad in matters of economic policy and human rights. A national strategy would then become a powerful new method of encouraging international ideals of democracy, and isolationism would be freed of its previous associations with appeasement, weakness, economic protectionism, and self-serving nationalism.

Nordlinger draws on the recent historical record to show that a national strategy would have lessened the perils of earlier decades, including those of the Cold War. While real dangers did exist during this period, engaged strategies, such as containment, too often exacerbated them. The United States could have effectively and far less expensively helped to deter Communist aggression in Europe and Asia by encouraging other nations to make larger investments in their own protection. Marshaling impressive empirical evidence in defense of a controversial position, this final work by a leading scholar of international affairs is essential reading for scholars, practitioners, and lay readers alike.

In this much-anticipated revision of their unique text, the editors bring together fifteen top scholars to highlight the importance of both internal and external forces in foreign policymaking.

Conflicts involving religion have returned to the forefront of international relations. And yet political scientists and policymakers have continued to assume that religion has long been privatized in the West. This secularist assumption ignores the contestation surrounding the category of the "secular" in international politics. The Politics of Secularism in International Relations shows why this thinking is flawed, and provides a powerful alternative.

Elizabeth Shakman Hurd argues that secularist divisions between religion and politics are not fixed, as commonly assumed, but socially and historically constructed. Examining the philosophical and historical legacy of the secularist traditions that shape European and American approaches to global politics, she shows why this matters for contemporary international relations, and in particular for two critical relationships: the United States and Iran, and the European Union and Turkey.

The Politics of Secularism in International Relations develops a new approach to religion and international relations that challenges realist, liberal, and constructivist assumptions that religion has been excluded from politics in the West. The first book to consider secularism as a form of political authority in its own right, it describes two forms of secularism and their far-reaching global consequences.
