Answer 2

The Korean War began when North Korean troops swept across the thirty-eighth parallel and quickly drove the troops of the Republic of Korea to the toe of the Korean peninsula. President Truman had stationed American troops in South Korea and an American fleet was already in Korean waters. Thanks to the absence of the Soviet delegation at the United Nations, Truman got that body to sponsor a "police action" in Korea to push the North Koreans back across the thirty-eighth parallel. The US made up most of the "police" in Korea. During the next presidential campaign, the Republican candidate Eisenhower promised to go to Korea and end hostilities. Eisenhower won the election and before he was inaugurated he went to Korea. He threatened to use atomic weaponry to end the war. That was probably a bluff, but it convinced the North Koreans to end hostilities in July, 1953. Korea returned to its previous division at the thirty-eighth parallel. The war did prove to the communist nations that the US was willing to defend its policy of containment and prevent any spread of communism, any where on the planet.
