Topic 8.7 Notes – America as a World Power

How the United States Used Power in the Cold War World

After 1945, the U.S. kept troops, bases, alliances, intelligence networks, and nuclear weapons around the world. The main goal was containment, which meant stopping the spread of Soviet power and communism.

The U.S. used a whole toolkit at once:

• Diplomacy through recognition, treaties, mediation, and the UN
• Foreign aid to tie countries to the U.S. economy and model
• Military alliances and bases to project power quickly
• CIA covert action to influence events without open war
• Troop deployments when leaders thought force was necessary
• Nuclear deterrence to scare the USSR away from direct attack
• Technological competition like the space race
• Peace Corps (1961), which sent Americans abroad as a softer way to build influence

That policy had a constant contradiction. The U.S. said it defended freedom and self-determination, but often supported dictators if they were anti-communist.

Decolonization made this even messier. New nations in Africa and Asia were emerging from European rule, and both superpowers tried to win them over. In Africa, independence came in waves across the 1950s through the 1970s, which helps explain why the continent became such an important Cold War battleground.

Decolonization in Africa

Many refused to join either bloc:

• Bandung Conference (1955) brought Asian and African leaders together against colonialism.
• Non-Aligned Movement (1961) organized countries trying to stay independent.
• Key leaders were Jawaharlal Nehru, Gamal Abdel Nasser, and Josip Broz Tito.

Congo

The Congo shows how local nationalism and Cold War fear got tangled together. Patrice Lumumba sought Soviet aid during a crisis after independence, so the U.S. and Belgium backed anti-Lumumba forces. Later, the U.S. supported Joseph Mobutu, even though he ruled as a dictator.

Latin America and Anti-Communist Intervention

In Latin America, U.S. leaders treated the region as a strategic sphere of influence and moved hard against leftist governments. The cases below center on the Caribbean, Central America, and South America.

Latin America and the Caribbean

• Guatemala 1954: Jacobo Árbenz pushed land reform that hurt United Fruit Company interests. The CIA’s Operation PBSUCCESS helped Carlos Castillo Armas overthrow him. This is the classic covert-action example.
• Cuba: Fidel Castro overthrew Fulgencio Batista in 1959. The Bay of Pigs invasion in 1961, a CIA-backed exile attack under Kennedy, failed badly.
• Cuban Missile Crisis 1962: The U.S. discovered Soviet missiles in Cuba. Kennedy used a naval quarantine. Khrushchev removed the missiles, the U.S. publicly promised not to invade Cuba, and secretly removed Jupiter missiles from Turkey. Results included the hotline and the Limited Nuclear Test Ban Treaty (1963).
• Reform and force: Kennedy’s Alliance for Progress tried to reduce revolution through development. Johnson still sent troops to the Dominican Republic in 1965 to stop “another Cuba.”
• Chile 1970-1973: Salvador Allende was elected and pursued socialism. The Nixon administration and CIA backed destabilization. After Augusto Pinochet’s 1973 coup, the U.S. supported his anti-communist dictatorship despite human-rights abuses.

Jimmy Carter shifted emphasis toward human rights and negotiated the Panama Canal treaties in 1977.

The Middle East and the Limits of American Influence

The U.S. wanted four things here at once: contain the USSR, protect oil, support Israel, and keep Arab allies. Those goals often collided.

Keep the region itself in mind as you review these events, especially the eastern Mediterranean, Israel and its neighbors, Egypt and the Suez Canal, Iran, and the Persian Gulf.

Political map of the Middle East

• UN partition plan 1947 split Palestine into Jewish and Arab states.
• Truman recognized Israel in 1948.
• The 1948 war created a large Palestinian refugee population.
• Iran 1953: Mohammad Mossadegh nationalized oil. A CIA and British-backed coup restored Shah Mohammad Reza Pahlavi. This is a key anti-communism + oil + covert action example.
• Suez Crisis 1956: Nasser nationalized the canal. Britain, France, and Israel attacked Egypt, but Eisenhower pressured them to withdraw. This showed old European empires weakening and U.S. influence rising.
• Eisenhower Doctrine promised aid against “international communism,” and in Lebanon 1958 the U.S. sent troops.
• OPEC was founded in 1960 by Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. The 1973 oil embargo showed oil producers had huge leverage.
• Camp David Accords 1978: Carter mediated between Anwar Sadat and Menachem Begin. Egypt recognized Israel, and Israel returned Sinai.
• Iranian Revolution and hostage crisis 1979-1981: Ayatollah Khomeini overthrew the shah. 52 Americans were held for 444 days. The failed Desert One rescue (April 1980) deepened the crisis. The Carter Doctrine, announced in January 1980, pledged to defend the Persian Gulf.

Nuclear Arms, the Space Race, and the Military-Industrial Complex

Global power depended on weapons, technology, and permanent military readiness. That also created fear at home.

• The nuclear triad was bombers, ICBMs, and submarine-launched missiles.
• MAD means mutual assured destruction. Each side could still destroy the other after a first strike, so nuclear war became a deterrent.
• Eisenhower’s massive retaliation relied heavily on the threat of overwhelming nuclear response.
• Kennedy’s flexible response built options short of nuclear war.

Americans argued over fallout, accident risk, giant defense budgets, and whether stockpiles went far beyond what deterrence required.

Military-industrial complex

In his 1961 Farewell Address, Eisenhower warned about the military-industrial complex, the close relationship among the military, defense contractors, Congress, universities, and federal agencies. He accepted the need for defense, but feared “unwarranted influence.”

Sputnik and the space race

• Sputnik (1957) made Americans fear Soviet scientific and missile superiority.
• The response included the National Defense Education Act (1958) and NASA (1958).
• Yuri Gagarin was the first human in orbit.
• Alan Shepard was the first American in space.
• John Glenn was the first American to orbit Earth.
• Kennedy set the Moon goal.
• Apollo 11 put Neil Armstrong and Buzz Aldrin on the Moon while Michael Collins remained in orbit.

Apollo 11 on the Moon

The Moon landing became the clearest symbol of how the space race tied science, prestige, and Cold War competition together.

Eisenhower and Kennedy agreed the U.S. had to lead globally. Their difference was tone. Eisenhower warned about permanent militarization. Kennedy’s Inaugural Address promised energetic world leadership and to “pay any price” for liberty.
