The creation of the North Atlantic Treaty Organization was one of the most important accomplishments of American diplomacy in countering the Soviet threat during the early days of the Cold War. Why and how such a reversal of a 150-year nonalignment policy by the United States was brought about, and how the goals of the treaty became a reality, are questions addressed here by a leading scholar of NATO. The importance of restoring Europe to strength and stability in the post-World War II years was as obvious to America as to its allies, but the means of achieving that goal were far from clear. The problem for European statesmen was how to secure much- needed American economic and military aid without sacrificing political independence. For American policymakers, in contrast, a degree of American control was seen as an essential quid pro quo. As Mr. Kaplan shows, the lengthy negotiations of 1947 and 1948 were chiefly concerned with reconciling these opposing views. For the Truman administration, the difficulties of achieving a treaty acceptable to the allies were matched by those of winning its acceptance by Congress and the public. Many Americans saw such an "entangling alliance" as a threat not only to American security but to the viability of the United Nations. Mr. Kaplan demonstrates the tortuous course of the debate on the treaty and the pivotal role of the communist invasion of South Korea in its ultimate approval. This authoritative study offers a timely reevaluation of the origins of an alliance that continues to play a critical role in the balance of power and in the prospects for world peace.

Alliance politics is a regular headline grabber. When a possible military crisis involving Russia, North Korea, or China rears its head, leaders and citizens alike raise concerns over the willingness of US allies to stand together. As rival powers have tightened their security cooperation, the United States has stepped up demands that its allies increase their defense spending and contribute more to military operations in the Middle East and elsewhere. The prospect of former President Donald Trump unilaterally ending alliances alarmed longstanding partners, even as NATO was welcoming new members into its ranks. Military Alliances in the Twenty-First Century is the first book to explore fully the politics that shape these security arrangements – from their initial formation through the various challenges that test them and, sometimes, lead to their demise. Across six thematic chapters, Alexander Lanoszka challenges conventional wisdom that has dominated our understanding of how military alliances have operated historically and into the present. Although military alliances today may seem uniquely hobbled by their internal difficulties, Lanoszka argues that they are in fact, by their very nature, prone to dysfunction.

This volume provides an overview of the evolution of NATO, alliances and global security governance in the twenty-first century.For so-long the cornerstone of the transatlantic partnership, the evolution of NATO has profound implications for the co-operative or competitive nature of transatlantic relations and regional and global security governance. As NATO moves into the twenty-first century its role, purpose, utility and very existence as the core transatlantic security alliance is increasingly questioned.For many observers with a more profound understanding of the evolution of NATO, such self-doubt has been a constant feature of NATO throughout its existence. But contemporary debates that question the utility of NATO and its collective security role do appear more strident, extreme and are expressed in a more determined fashion than arguments between allies on how best to secure the Cold War collective defence role. The Iraq War widened the spectrum of opinion as to NATO's future to an unprecedented degree. An interesting feature of this intense debate is that only the extremes tend to prick public consciousness - NATO as train-wreck or NATO in robust and rude health.Understanding NATO in the 21st Centurywill appeal to students of NATO, international security and international relations in general.
