Chapters 25-29

Key Concepts - from College Board

After World War II, the United States grappled with prosperity and unfamiliar international responsibilities, while struggling to live up to its ideals. 

Key Concept 8.1: The United States responded to an uncertain and unstable postwar world by asserting and working to maintain a position of global leadership, with far-reaching domestic and international consequences.

I. United States policymakers engaged in a Cold War with the authoritarian Soviet Union, seeking to limit the growth of Communist military power and ideological influence, create a free-market global economy, and build an international security system.

  1. As postwar tensions dissolved the wartime alliance between Western democracies and the Soviet Union, the United States developed a foreign policy based on collective security, international aid, and economic institutions that bolstered non-Communist nations.
  2. Concerned by expansionist Communist ideology and Soviet repression, the United States sought to contain communism through a variety of measures, including major military engagements in Korea and Vietnam.
  3. The Cold War fluctuated between periods of direct and indirect military confrontation and periods of mutual coexistence (or détente).
  4. 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.
  5. Cold War competition extended to Latin America, where the U.S. supported non-Communist regimes that had varying levels of commitment to democracy.

  1. Americans debated policies and methods designed to expose suspected communists within the United States even as both parties supported the broader strategy of containing communism.
  2. Although anticommunist foreign policy faced little domestic opposition in previous years, the Vietnam War inspired sizable and passionate antiwar protests that became more numerous as the war escalated, and sometimes led to violence.

  4. 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.
