Secret Alliances

This topical book explores key motivating factors in the formation and dissolution of secret alliances between states. Matthew Millard examines the role of a variety of different factors in the formation, endurance, and termination of secret alliances, analyzing key case studies across Africa, Asia, and Europe that showcase the consequences of broken secret alliances.

Using historical examples and quantitative data, Millard discusses why states refrain from institutionalizing their covert alliances, evaluating whether these are more or less enduring than public ones. He suggests that secret alliances form between two states when there is a breakdown in bargaining with a third target state, resulting in alliances that do not provide public signals of cooperation. Furthermore, the stakes over what is being divided up are more likely to result in war than in public alliances. Chapters debate the advantages and disadvantages of forming secret alliances and identify reasons that countries might renege on their obligations, including changes in leadership, the security environment, and conflicting military commitments.



Secret Alliances is a vital read for students and scholars in political science and public policy, international relations, and security studies. Its novel insights make this book an essential reference tool for practitioners and policymakers in politics and foreign policy.
