The U.S. role in the world refers to the overall character, purpose, or direction of U.S. participation in international affairs and the country's overall relationship to the rest of the world. The U.S. role in the world can be viewed as establishing the overall context or framework for U.S. policymakers for developing, implementing, and measuring the success of U.S. policies and actions on specific international issues, and for foreign countries or other observers for interpreting and understanding U.S. actions on the world stage. While descriptions of the U.S. role in the world since the end of World War II vary in their specifics, it can be described in general terms as consisting of four key elements: global leadership; defense and promotion of the liberal international order; defense and promotion of freedom, democracy, and human rights; and prevention of the emergence of regional hegemons in Eurasia. The issue for Congress is whether the U.S. role in the world is changing, and if so, what implications this might have for the United States and the world. A change in the U.S. role could have significant and even profound effects on U.S. security, freedom, and prosperity. It could significantly affect U.S. policy in areas such as relations with allies and other countries, defense plans and programs, trade and international finance, foreign assistance, and human rights. Some observers, particularly critics of the Trump Administration, argue that under the Trump Administration, the United States is substantially changing the U.S. role in the world. Other observers, particularly supporters of the Trump Administration, while acknowledging that the Trump Administration has changed U.S. foreign policy in a number of areas compared to policies pursued by the Obama Administration, argue that under the Trump Administration, there has been less change and more continuity regarding the U.S. role in the world. Some observers who assess that the United States under the Trump Administration is substantially changing the U.S. role in the world-particularly critics of the Trump Administration, and also some who were critical of the Obama Administration-view the implications of that change as undesirable. They view the change as an unnecessary retreat from U.S. global leadership and a gratuitous discarding of long-held U.S. values, and judge it to be an unforced error of immense proportions-a needless and self-defeating squandering of something of great value to the United States that the United States had worked to build and maintain for 70 years. Other observers who assess that there has been a change in the U.S. role in the world in recent years-particularly supporters of the Trump Administration, but also some observers who were arguing even prior to the Trump Administration in favor of a more restrained U.S. role in the world-view the change in the U.S. role, or at least certain aspects of it, as helpful for responding to changed U.S. and global circumstances and for defending U.S. interests. Congress's decisions regarding the U.S role in the world could have significant implications for numerous policies, plans, programs, and budgets, and for the role of Congress relative to that of the executive branch in U.S. foreign policymaking.

America has a long history of diplomacy–ranging from Benjamin Franklin, Alexander Hamilton, and Thomas Jefferson to Henry Kissinger, Ronald Reagan, and James Baker–now is your chance to see the impact these Americans have had on the world. Recounting the actors and events of U.S. foreign policy, Zoellick identifies five traditions that have emerged from America's encounters with the world: the importance of North America; the special roles trading, transnational, and technological relations play in defining ties with others; changing attitudes toward alliances and ways of ordering connections among states; the need for public support, especially through Congress; and the belief that American policy should serve a larger purpose. These traditions frame a closing review of post-Cold War presidencies, which Zoellick foresees serving as guideposts for the future. Both a sweeping work of history and an insightful guide to U.S. diplomacy past and present, America in the World serves as an informative companion and practical adviser to readers seeking to understand the strategic and immediate challenges of U.S. foreign policy during an era of transformation.

Winner, 2023 Joseph Fletcher Prize for Best Edited Book in Historical International Relations, History Section, International Studies Association Ideology drives American foreign policy in ways seen and unseen. Racialized notions of subjecthood and civilization underlay the political revolution of eighteenth-century white colonizers; neoconservatism, neoliberalism, and unilateralism propelled the post–Cold War United States to unleash catastrophe in the Middle East. Ideologies order and explain the world, project the illusion of controllable outcomes, and often explain success and failure. How does the history of U.S. foreign relations appear differently when viewed through the lens of ideology? This book explores the ideological landscape of international relations from the colonial era to the present. Contributors examine ideologies developed to justify—or resist—white settler colonialism and free-trade imperialism, and they discuss the role of nationalism in immigration policy. The book reveals new insights on the role of ideas at the intersection of U.S. foreign and domestic policy and politics. It shows how the ideals coded as “civilization,” “freedom,” and “democracy” legitimized U.S. military interventions and enabled foreign leaders to turn American power to their benefit. The book traces the ideological struggle over competing visions of democracy and of American democracy’s place in the world and in history. It highlights sources beyond the realm of traditional diplomatic history, including nonstate actors and historically marginalized voices. Featuring the foremost specialists as well as rising stars, this book offers a foundational statement on the intellectual history of U.S. foreign policy.

Earl Fry explores the forces behind the rise of state and local influence in foreign affairs.

Mission Failure argues that, in the past 25 years, the U.S. military has turned to missions that are largely humanitarian and socio-political - and that this ideologically-driven foreign policy generally leads to failure.
