Why did the US get involved in the Korean War?

  1. America wanted not just to contain communism - they also wanted to prevent the domino effect. Truman was worried that if Korea fell, the next country to fall would be Japan, which was very important for American trade. This was probably the most important reason for America’s involvement in the war.
  2. Many in America believed that they had a responsibility to act because of their commitment to the Truman Doctrine. They had promised to help countries who were threatened by communism.
  3. The Americans believed that the USSR was behind the North Korean invasion and they were determined to stop Stalin.
  4. The United States believed it could win and believed that China would not intervene. They also hoped to take advantage of the USSR’s boycott of the UN to get the UN to agree to military help for South Korea.
  5. The advance of communism elsewhere made America more determined. For example, the USSR testing its first atomic bomb in 1949; the events of the Berlin blockade in 1948-49; and China turning communist in 1949.

Background information

- From 1910 Korea had been controlled by the Japanese. At the end of WW2 in 1945, the Japanese troops based in North Korea surrendered to the Soviet Union while those based in south Korea surrendered to the Americans.
- A temporary dividing line was drawn up between the north and south along the 38th parallel.
- Free elections were to be held for a united, democratic Korea.

- In 1948, separate elections were held. The south became the Republic of Korea, a capitalist dictatorship. In the north, now called the Democratic People's Republic of Korea, there was a communist dictatorship, supported by the Soviet Union.

- In 1950, North Korean soldiers, armed with Russian weapons invaded South Korea.

Why did North Korea invade South Korea in 1950?

- Kim-Il Sung wanted a united Korea under communist rule: he had good reason to think he would be successful with the support of Stalin and Mao Zedong (Soviet Union and China)
- North Korea's armed forces, using weapons supplied b the Soviet Union, were stronger than the armed forces of South Korea.

- Now China and the Soviet Union had the atomic bomb, Kim thought an American response would be unlikely as Korea was not a major American priority.

How did the US become involved?

- President Truman saw the invasion as a communist plot and acted quickly.
- He sent the US Seventh Fleet to try and prevent a Chinese attack on Formosa. He ordered General MacArthur to go to Korea with military supplies

- The UN Security Council met on the day that the North Korean troops crossed the border into South Korea An American resolution was passed at the UN, demanding the withdrawal of the North Koreans. Its passing was made possible by the absence of the Soviet Union. At that time the Soviets were not present as a protest against America's treatment of communist China. There were no Russians present to use the veto either.

- As North Korea had no intention of withdrawing, a second American resolution was out forward in June. A third resolution 10 days later made clear how military forces were to be deployed.
- Troops from America and 15 other countries were sent to assist South Korea

What was the attitude of the USA to the invasion of South Korea?

- As they had been closely involved in the establishment of the Republic of Korea, they gave support. Under their policy of containment, the USA was determined to halt further communist expansion. The actions of North Korea were seen by America as part of Moscow's attempt to gain world domination.

- The US feared that success in South Korea would encourage communist China to attack on Formosa. If South Korea and Formosa fell to the communists, Japan would come under threat. From America's point of view, the fall of South Korea, Formosa (the base of the non-communist Chinese) and Japan to the communists would represent a major shift in world power balance. The most effective way to prevent this was to oppose the North Korean invasion of South Korea.

- If the UN had not acted, it could have been likely that America would have acted on its own. American gave its full support to the UN. The UN forces were commanded by the American general, MacArthur, who took his orders directly from Truman rather than UN officials. Half of the ground forces were American, together with over 90% of the air forces and over 85% of the naval forces.

What happened ?

- By September 1950, only a small piece of Korea was not controlled by the communists but following UN troops landing at Inchon the communists were pushed back into North Korea. Truman decided to pursue the communists and so the UN troops invaded North Korea.

- The Chinese leader Mao Zedong was angered by this action, sending a large Chinese army to attack MacArthur's army. In 1951 the UN army was forced to retreat back into the South, followed by the communists.

- A UN counter attack forced Chinese and North Koreans back to the 38th parallel. Truman did not want a lengthy or costly war in Asia but MacArthur wanted to carry on into China. He suggested the use of the atomic bomb. Truman therefore dismissed MacArthur in April 1931.

- In 1953, a ceasefire was agreed which left Korea as two separate countries. Truman settled for communism being contained in North Korea.

What were the results of the Korean War for the UN?

- The UN had used military sanctions against an aggressor, showing that it was more purposeful than the League of Nations had ever been.

- The UN failed in its objective of a "unified, independent and democratic government" for Korea.

- The massive involvement and influence of the USA made it look more like an American action than one by the UN.

- UN support for the American motion had only been achieved by chance: when the Korean war began, Russia was boycotting the UN Security Council and so there were no Russian delegates to veto the UN decision

What were the results of the Korean War for the USA?

- 40,000 troops died but many more would have perished if MacArthur had got his war (use of the atomic bomb)

- The US policy of containment had been successful as the spread of communism into South Korea was prevented.

- After MacArthur's invasion of the North, the Soviet Union could say that the US was an expansionist country.

- Many American Republicans felt that the USA had missed an opportunity to destroy communism in China. This feeling contributed towards the excesses of McCarthyism in America.

- American relations with China, as well as the Soviet Union, were now strained; bringing a new dimension to the Cold War.

Why did the US go into the Korean War and what was the result?

On June 27, 1950, President Truman ordered U.S. forces to South Korea to repulse the North's invasion. “Democrats needed to look tough on communism,” Kim says. “Truman used Korea to send a message that the U.S. will contain communism and come to the aid of their allies.”

Why did the US go to war in Korea and what was the result quizlet?

Why did the U.S get involved in the Korean War? Primarily because of the threat of Communist expansion by China, along with fear that the SU was working with China to create bombs. Plus, Korea was positioned at the 38th Parallel, which makes it an important point to hold in the area for political control.

What was the outcome of the US involvement in the Korean War?

After three years of a bloody and frustrating war, the United States, the People's Republic of China, North Korea, and South Korea agree to an armistice, bringing the fighting of the Korean War to an end. The armistice ended America's first experiment with the Cold War concept of “limited war.”
