An in-depth look at how the ideas formulated by the interwar League of Nations shaped American thinking on the modern global order. In Plowshares into Swords, David Ekbladh recaptures the power of knowledge and information developed between World War I and World War II by an international society of institutions and individuals committed to liberal international order and given focus by the League of Nations in Geneva. That information and analysis revolutionized critical debates in a world in crisis. In doing so, Ekbladh transforms conventional understandings of the United States' postwar hegemony, showing that important elements of it were profoundly influenced by ideas that emerged from international exchanges. The League's work was one part of a larger transnational movement that included the United States and which saw the emergence of concepts like national income, gross domestic product, and other attempts to define and improve the standards of living, as well as new approaches to old questions about the role of government. Forged as tools for peace these ideas were beaten into weapons as World War II threatened. Ekbladh recounts how, though the US had never been a member of the organization, vital parts of the League were rescued after the fall of France in 1940 and given asylum at the Institute for Advanced Study in Princeton. However, this presence in the US is just one reason its already well-regarded economic analyses and example were readily mobilized by influential American and international figures for an Allied "war of ideas," plans for a postwar world, and even blueprints for the new United Nations. How did this body of information become so valuable? As Ekbladh makes clear, the answer is that information and analysis themselves became crucial currencies in global affairs: to sustain a modern, liberal global order, a steady stream of information about economics, politics, and society was, and remains, indispensable.

"The Great American Mission" traces how America's global modernization efforts during the twentieth century were a means to remake the world in its own image. David Ekbladh shows that the emerging concept of modernization combined existing development ideas from the Depression. He describes how ambitious New Deal programs like the Tennessee Valley Authority became symbols of American liberalism's ability to marshal the social sciences, state planning, civil society, and technology to produce extensive social and economic change. For proponents, it became a valuable weapon to check the influence of menacing ideologies such as Fascism and Communism.

Modernization took on profound geopolitical importance as the United States grappled with these threats. After World War II, modernization remained a means to contain the growing influence of the Soviet Union. Ekbladh demonstrates how U.S.-led nation-building efforts in global hot spots, enlisting an array of nongovernmental groups and international organizations, were a basic part of American strategy in the Cold War.

However, a close connection to the Vietnam War and the upheavals of the 1960s would discredit modernization. The end of the Cold War further obscured modernization's mission, but many of its assumptions regained prominence after September 11 as the United States moved to contain new threats. Using new sources and perspectives, "The Great American Mission" offers new and challenging interpretations of America's ideological motivations and humanitarian responsibilities abroad.

As American interests assumed global proportions after 1945, policy makers were faced with the challenge of prioritizing various regions and determining the extent to which the United States was prepared to defend and support them. Superpowers and developing nations soon became inextricably linked and decolonizing states such as Vietnam, India, and Egypt assumed a central role in the ideological struggle between the United States and the Soviet Union. As the twentieth century came to an end, many of the challenges of the Cold War became even more complex as the Soviet Union collapsed and new threats arose. Featuring original essays by leading scholars, Foreign Policy at the Periphery examines relationships among new nations and the United States from the end of the Second World War through the global war on terror. Rather than reassessing familiar flashpoints of US foreign policy, the contributors explore neglected but significant developments such as the efforts of evangelical missionaries in the Congo, the 1958 stabilization agreement with Argentina, Henry Kissinger's policies toward Latin America during the 1970s, and the financing of terrorism in Libya via petrodollars. Blending new, internationalist approaches to diplomatic history with newly released archival materials, Foreign Policy at the Periphery brings together diverse strands of scholarship to address compelling issues in modern world history.
