The Cold War Escalates: Korea & 1950s Foreign Policy
1 of 10
What event triggered the start of the Korean War in June \(1950\)?
The war began when communist North Korea, backed by the Soviet Union, invaded South Korea, which was supported by the United States. This crossed the \(38th\) parallel, the line dividing the two countries.
How did the United States officially justify its military intervention in the Korean War?
The U.S. intervened as part of a United Nations "police action." The UN Security Council, with the Soviet Union absent, passed a resolution calling on member states to aid South Korea in repelling the invasion.
Why did President Truman relieve General Douglas MacArthur of his command in Korea?
Truman fired MacArthur for insubordination. MacArthur publicly criticized Truman's policy of a limited war and advocated for expanding the conflict into China, including the use of nuclear weapons, which directly challenged civilian control of the military.
How did the Korean War end in \(1953\)?
The war ended in a stalemate with the signing of an armistice. The agreement re-established the border between North and South Korea near the original \(38th\) parallel and created a demilitarized zone (DMZ) that still exists today.
What was President Eisenhower's foreign policy of "Massive Retaliation"?
This policy, articulated by Secretary of State John Foster Dulles, stated that the U.S. would respond to any communist aggression not with conventional forces, but with a massive nuclear strike. It was meant to be a cost-effective deterrent.
What is "Brinkmanship"?
Brinkmanship is the practice of pursuing a dangerous policy to the limits of safety before stopping. In the Cold War context, it meant being willing to go to the brink of nuclear war to force an opponent to back down.
What was the "Domino Theory," often cited by President Eisenhower?
The Domino Theory was the belief that if one country in a region fell to communism, then the surrounding countries would inevitably follow in a domino effect. This theory was used to justify U.S. intervention in Vietnam.
What was the Eisenhower Doctrine?
Announced in \(1957\), the Eisenhower Doctrine extended the Truman Doctrine to the Middle East. It pledged U.S. military and economic aid to any Middle Eastern nation resisting communist aggression.
What was the impact of the Soviet Union's launch of Sputnik in \(1957\)?
Sputnik, the first artificial satellite, shocked the U.S. and sparked fears of a "missile gap." It led directly to the creation of NASA and the passage of the National Defense Education Act to boost science and math education, officially starting the Space Race.
What was the U-2 Incident in \(1960\)?
An American U-2 spy plane was shot down over the Soviet Union. The incident led to the collapse of a planned summit between Eisenhower and Khrushchev and greatly increased Cold War tensions.
