In Reliability and Alliance Interdependence, Iain D. Henry argues for a more sophisticated approach to alliance politics and ideas of interdependence. It is often assumed that if the United States failed to defend an ally, then this disloyalty would instantly and irrevocably damage US alliances across the globe. Henry proposes that such damage is by no means inevitable and that predictions of disaster are dangerously simplistic. If other allies fear the risks of military escalation more than the consequences of the United States abandoning an ally, then they will welcome, encourage, and even praise such an instance of disloyalty. It is also often assumed that alliance interdependence only constrains US policy options, but Henry shows how the United States can manipulate interdependence to set an example of what constitutes acceptable allied behavior. Using declassified documents, Henry explores five case studies involving US alliances with South Korea, Japan, the Republic of China, the Philippines, Australia, and New Zealand. Reliability and Alliance Interdependence makes a substantial contribution to our understanding of how America's alliances in Asia function as an interdependent system.

Throughout the Cold War, US officials feared that Washington's disloyalty to one ally would automatically cause other allies to doubt America's security reliability. These doubts could prompt allies to adopt policies of neutrality, or even defect to the Communist bloc. This dissertation challenges the conventional wisdom - that alliance interdependence is underpinned by loyalty - by proposing the "alliance audience effect". The alliance audience effect framework shows that discrete alliance commitments can be practically interdependent, but that this interdependence is not underpinned by loyalty. Through an investigation of Cold War case studies, using a process tracing methodology and archival research, this dissertation argues that US allies in Asia were unconcerned about whether America was loyal to other allied states. Instead, they monitored America's behaviour in order to reassure themselves that the US was reliable: that their own alliance did not pose risks of either abandonment or entrapment. When allies feared abandonment, they encouraged America to solidify its presence in Asia and adopt a more aggressive posture. But when allies feared entrapment, they encouraged conciliatory US policies and worked to restrain Washington, thus reducing the risk of conflict. In some cases, American disloyalty to one ally was welcomed, or even encouraged, by other allies, as this disloyalty better served their own interests. Like the adage that "one man's terrorist is another man's freedom fighter", this dissertation shows that one state's disloyal ally can be another state's reliable ally. Because US allies have different interests, they will have different views of American behaviour: one ally might praise an instance of US disloyalty as proof of reliability, while another ally might condemn Washington for unreliability. In short, reliability is not synonymous with loyalty, and America does not have a collective alliance loyalty reputation. Beyond the allied perspective, this research also demonstrates how the United States managed its alliances and used alliance interdependence to achieve its own ends. This dissertation's findings have relevance for the alliance politics literature, theories about international reputation, and the practical management of alliances.

Military alliances are a constant feature in international politics, and a better understanding of them can directly impact world affairs. This book examines why alliances endure or collapse. As a distinctive feature, it analyses asymmetric alliances focusing on the junior allies’ decision to continue or terminate a military agreement. It deepens our knowledge of alliance cohesion and erosion, investigating the relevance of the weaker side’s preferences and behavior in alliance politics. The author examines the literature on alliance persistence and termination and puts forward a theoretical model that helps interpret historical and contemporary cases in a way that is useful for expert researchers and non-expert readers alike.

The Oxford Handbook of Space Security focuses on the interaction between space technology and international and national security processes. Saadia M. Pekkanen and P.J. Blount have gathered a group of key scholars who bring a range of analytical and theoretical perspectives to take an analytically-eclectic approach to assessing space security from an international relations (IR) theory perspective. Bringing together scholarship from a group of leading experts, this volume explains how these contemporary changes will affect future security in, from, and through space.

The Supply Side of Security conceptualizes military alliances as contracts for exchanging goods and services. At the international level, the market for these contracts is shaped by how many countries can supply security. Tongfi Kim identifies the supply of policy concessions and military commitments as the main factors that explain the bargaining power of a state in a potential or existing alliance. Additionally, three variables of a state's domestic politics significantly affect its negotiating power: whether there is strong domestic opposition to the alliance, whether the state's leader is pro-alliance, and whether that leader is vulnerable. Kim then looks beyond existing alliance literature, which focuses on threats, to produce a deductive theory based on analysis of how the global power structure and domestic politics affect alliances. As China becomes stronger and the U.S. military budget shrinks, The Supply Side of Security shows that these countries should be understood not just as competing threats, but as competing security suppliers.

Timothy W. Crawford's The Power to Divide examines the use of wedge strategies, a form of divisive statecraft designed to isolate adversaries from allies and potential supporters to gain key advantages. With a multidimensional argument about the power of accommodation in competition, and a survey of alliance diplomacy around both World Wars, The Power to Divide artfully analyzes the past and future performance of wedge strategy in great power politics. Crawford argues that nations attempting to use wedge strategy do best when they credibly accommodate likely or established allies of their enemies. He also argues that a divider's own alliances can pose obstacles to success and explains the conditions that help dividers overcome them. He advances these claims in eight focused studies of alliance diplomacy surrounding the World Wars, derived from published official documents and secondary histories. Through those narratives, Crawford adeptly assesses the record of countries that tried an accommodative wedge strategy, and why ultimately, they succeeded or failed. These calculated actions often became turning points, desired or not, in a nation's established power. For policymakers today facing threats to power from great power competitors, Crawford argues that a deeper historical and theoretical grasp of the role of these wedge strategies in alliance politics and grand strategy is necessary. Crawford drives home the contemporary relevance of the analysis with a survey of China's potential to use such strategies to divide India from the US, and the United States' potential to use them to forestall a China-Russia alliance, and closes with a review of key theoretical insights for policy.

This book analyses the ways in which foreign policy actors in Asia have responded to the emerging great power conflict between the US and the People's Republic of China focusing on medium and small states across the Indo-Pacific. The book offers a much-needed counterpoint to existing analyses on the Indo-Pacific and China’s BRI and presents a new perspective by examining how great power politics are locally reinterpreted, conditioned, or at times even contested. It illustrates the policy-level challenges which the US-China rivalry poses for established political and economic practices and outlines how these challenges can be best addressed by smaller states and their societies. A timely assessment of the power play in the Indo-Pacific with the angle of Sino-American rivalry, this book makes an important contribution to the study of Political Science, International Relations, Asian Studies and Security Studies.
