What were the reasons behind the US intervention in the Korean War?

The Korean War was fought between North Korea, which was backed by China and the Soviet Union, and South Korea, which was backed by the United Nations, primarily the United States. The war lasted from 1950 to 1953 and ended with an armistice, which created the Korean Demilitarized Zone (DMZ) that separates North and South Korea.

The reasons behind US intervention in the Korean War were primarily related to the Cold War, which was at its peak at the time. The US saw the spread of communism as a major threat to its national security and sought to contain it. When North Korea invaded South Korea on June 25, 1950, the US saw it as an opportunity to stop the spread of communism in the region and support its ally, South Korea.

Another reason behind US intervention was the geopolitical importance of the Korean peninsula. The US wanted to maintain its influence in the region and prevent the spread of communism to other countries in Asia. Moreover, the US wanted to avoid a direct confrontation with the Soviet Union and China, who were supporting North Korea, and instead, preferred to fight a limited war.

During the war, the US provided significant military and economic assistance to South Korea, including troops, supplies, and weaponry. The US forces played a significant role in pushing back North Korean forces and regaining control of South Korea. The war ended with an armistice, which created a buffer zone between the two Koreas, but a formal peace treaty was never signed, and the two Koreas remain technically at war to this day.
