The United States responded to an uncertain and unstable postwar world by asserting and attempting to defend a position of global leadership, with far-reaching domestic and international consequences.
I. After World War II, the United States sought to stem the growth of Communist military power and ideological influence, create a stable global economy, and build an international security system.
- The United States developed a foreign policy based on collective security and a multilateral economic framework that bolstered non-Communist nations.
- The United States sought to “contain” Soviet-dominated communism through a variety of measures, including military engagements in Korea and Vietnam.
- development of hydrogen bomb, massive retaliation, space race
- The Cold War fluctuated between periods of direct and indirect military confrontation and periods of mutual coexistence (or détente).
II. As the United States focused on containing communism, it faced increasingly complex foreign policy issues, including decolonization, shifting international alignments and regional conflicts, and global economic and environmental changes.
- Postwar decolonization and the emergence of powerful nationalist movements in Asia, Africa, and the Middle East led both sides in the Cold War to seek allies among new nations, many of which remained nonaligned.
- Cold War competition extended to Latin America, where the U.S. supported non-Communist regimes with varying levels of commitment to democracy.
- Ideological, military, and economic concerns shaped U.S. involvement in the Middle East, with several oil crises in the region eventually sparking attempts at creating a national energy policy.
III. Cold War policies led to continued public debates over the power of the federal government, acceptable means for pursuing international and domestic goals, and the proper balance between liberty and order.
- Americans debated policies and methods designed to root out Communists within the United States even as both parties tended to support the broader Cold War strategy of containing communism.
