Glenn H. Snyder creates a theory of alliances by deductive reasoning about the international system, by integrating ideas from neorealism, coalition formation, bargaining, and game theory, and by empirical generalization from international history. Using cases from 1879 to 1914 to present a theory of alliance formation and management in a multipolar international system, he focuses particularly on three cases--Austria-Germany, Austria-Germany-Russia, and France-Russia--and examines twenty-two episodes of intra-alliance bargaining. Snyder develops the concept of the alliance security dilemma as a vehicle for examining influence relations between allies. He draws parallels between alliance and adversary bargaining and shows how the two intersect. He assesses the role of alliance norms and the interplay of concerts and alliances.His great achievement in Alliance Politics is to have crafted definitive scholarly insights in a way that is useful and interesting not only to the specialist in security affairs but also to any reasonably informed person trying to understand world affairs.

This Oxford Handbook is the definitive volume on the state of international security and the academic field of security studies. It provides a tour of the most innovative and exciting news areas of research as well as major developments in established lines of inquiry. It presents a comprehensive portrait of an exciting field, with a distinctively forward-looking theme, focusing on the question: what does it mean to think about the future of international security? The key assumption underpinning this volume is that all scholarly claims about international security, both normative and positive, have implications for the future. By examining international security to extract implications for the future, the volume provides clarity about the real meaning and practical implications for those involved in this field. Yet, contributions to this volume are not exclusively forecasts or prognostications, and the volume reflects the fact that, within the field of security studies, there are diverse views on how to think about the future. Readers will find in this volume some of the most influential mainstream (positivist) voices in the field of international security as well as some of the best known scholars representing various branches of critical thinking about security. The topics covered in the Handbook range from conventional international security themes such as arms control, alliances and Great Power politics, to "new security" issues such as global health, the roles of non-state actors, cyber-security, and the power of visual representations in international security. The Oxford Handbooks of International Relations is a twelve-volume set of reference books offering authoritative and innovative engagements with the principal sub-fields of International Relations. The series as a whole is under the General Editorship of Christian Reus-Smith of the University of Queensland and Duncan Snidal of the University of Oxford, with each volume edited by a distinguished pair of specialists in their respective fields. The series both surveys the broad terrain of International Relations scholarship and reshapes it, pushing each sub-field in challenging new directions. Following the example of the original Reus-Smit and Snidal The Oxford Handbook of International Relations, each volume is organized around a strong central thematic by a pair of scholars drawn from alternative perspectives, reading its sub-field in an entirely new way, and pushing scholarship in challenging new directions.

Allied nations often stop each other from going to war. Some countries even form alliances with the specific intent of restraining another power and thereby preventing war. Furthermore, restraint often becomes an issue in existing alliances as one ally wants to start a war, launch a military intervention, or pursue some other risky military policy while the other ally balks. In Warring Friends, Jeremy Pressman draws on and critiques realist, normative, and institutionalist understandings of how alliance decisions are made. Alliance restraint often has a role to play both in the genesis of alliances and in their continuation. As this book demonstrates, an external power can apply the brakes to an incipient conflict, and even unheeded advice can aid in clarifying national goals. The power differentials between allies in these partnerships are influenced by leadership unity, deception, policy substitutes, and national security priorities. Recent controversy over the complicated relationship between the U.S. and Israeli governments—especially in regard to military and security concerns—is a reminder that the alliance has never been easy or straightforward. Pressman highlights multiple episodes during which the United States attempted to restrain Israel's military policies: Israeli nuclear proliferation during the Kennedy Administration; the 1967 Arab-Israeli War; preventing an Israeli preemptive attack in 1973; a small Israeli operation in Lebanon in 1977; the Israeli invasion of Lebanon in 1982; and Israeli action during the Gulf War of 1991. As Pressman shows, U.S. initiatives were successful only in 1973, 1977, and 1991, and tensions have flared up again recently as a result of Israeli arms sales to China. Pressman also illuminates aspects of the Anglo-American special relationship as revealed in several cases: British nonintervention in Iran in 1951; U.S. nonintervention in Indochina in 1954; U.S. commitments to Taiwan that Britain opposed, 1954-1955; and British intervention and then withdrawal during the Suez War of 1956. These historical examples go far to explain the context within which the Blair administration failed to prevent the U.S. government from pursuing war in Iraq at a time of unprecedented American power.

Some of the most brutal and long-lasting civil wars of our time involve the rapid formation and disintegration of alliances among warring groups, as well as fractionalization within them. It would be natural to suppose that warring groups form alliances based on shared identity considerations - such as Christian groups allying with Christian groups - but this is not what we see. Two groups that identify themselves as bitter foes one day, on the basis of some identity narrative, might be allies the next day and vice versa. Nor is any group, however homogeneous, safe from internal fractionalization. Rather, looking closely at the civil wars in Afghanistan and Bosnia and testing against the broader universe of fifty-three cases of multiparty civil wars, Fotini Christia finds that the relative power distribution between and within various warring groups is the primary driving force behind alliance formation, alliance changes, group splits and internal group takeovers.

A close look at the evolution of American political alliances in Asia and their future While the American alliance system in Asia has been fundamental to the region's security and prosperity for seven decades, today it encounters challenges from the growth of China-based regional organizations. How was the American alliance system originally established in Asia, and is it currently under threat? How are competing security designs being influenced by the United States and China? In Powerplay, Victor Cha draws from theories about alliances, unipolarity, and regime complexity to examine the evolution of the U.S. alliance system and the reasons for its continued importance in Asia and the world. Cha delves into the fears, motivations, and aspirations of the Truman and Eisenhower presidencies as they contemplated alliances with the Republic of China, Republic of Korea, and Japan at the outset of the Cold War. Their choice of a bilateral "hub and spokes" security design for Asia was entirely different from the system created in Europe, but it was essential for its time. Cha argues that the alliance system’s innovations in the twenty-first century contribute to its resiliency in the face of China’s increasing prominence, and that the task for the world is not to choose between American and Chinese institutions, but to maximize stability and economic progress amid Asia’s increasingly complex political landscape. Exploring U.S. bilateral relations in Asia after World War II, Powerplay takes an original look at how global alliances are achieved and maintained.

The book focuses on the relations between small states and alliances. It is on why, how and under what conditions states engage in alliances. What are the benefits and costs of alliances? How are the benefits and costs of alliances allocated among their members? What determines who allies with whom? Can small states still pursue their own security interests within an alliance? Can they even become integral part of an alliance? Scholars, practitioners, policy-makers and advisors from several countries discuss these issues. They address historical, empirical and theoretical topics and give policy recommendations.

A broad-ranging study of the relationship between alliances and the conduct of grand strategy, examined through historical case studies.
