Rapp-Hooper takes on directly and convincingly the Trumpian critique that alliances are not worth the investment and have led the nation to fight other people's battles for them. Her deep erudition, crisp prose style, and innate brilliance shine through on most every page. -Boston Review

The threat of COVID-19 has bolstered her argument, making plain both the importance of the alliance system and the imperative to adapt alliances to new ends. -Foreign Policy

Musters rock-solid evidence to demonstrate what policymakers have long believed: that America's alliances are a remarkably effective foreign policy tool. -Stephen Hadley, former National Security Advisor

Argues persuasively that the complex alliance system instituted after the devastation of World War II has proven remarkably successful. -Kirkus Reviews

For the first 150 years of its existence, heeding George Washington's warning about the dangers of "entangling alliances," the United States had just one alliance—a valuable but highly controversial military arrangement with France. That changed dramatically with the Second World War. Between 1948 and 1955, the United States extended defensive security guarantees to twenty-three countries in Europe and Asia. Seventy years later, it is allied with thirty-seven countries.

Today the alliance system is threatened from without and within. China and Russia seek to break America's alliances through conflict and non-military erosion, while US politicians and voters, skeptical of costs, believe we may be better off without them. But what if the alliance system is a victim of its own quiet success? Mira Rapp-Hooper argues that a grand strategy focused on allied defence, deterrence, and assurance helped to keep the peace throughout the Cold War and that the alliance system remains critical to America's safety and prosperity in the twenty-first century.
