Was the American involvement in Korean War a good idea

Yeah ... it was a good idea because it was a war against the forces of international communism itself

Explanation:

The Korean War (1950-1953) began when the North Korean Communist army crossed the 38th Parallel and invaded non-Communist South Korea. As Kim Il-sung's North Korean army, armed with Soviet tanks, quickly overran South Korea, the United States came to South Korea's aid ... This Chinese army attacked the US/UN/ROK forces.

The Cold War was an important cause in the Korean War. Relations between the two occupying powers were bad and when China became Communist in October 1949, the President of the USA, Harry Truman, was very worried that other countries around China may also become Communist, such as Japan.

This decision coincided with the United States withdrawing the last remaining combat troops from South Korea. North Korea saw its opportunity and attacked South Korean forces at the 38th parallel on June 25, 1950 and thus initiating the Korean War.

This invasion was the first military action of the Cold War. By July, American troops had entered the war on South Korea's behalf. As far as American officials were concerned, it was a war against the forces of international communism itself.
