In 1951 Gen. Douglas MacArthur had suggested using nuclear weapons during the Korean War (1950-1953). However, President Truman along with the majority of Congress disagreed and dismissed General MacArthur.
Personally, I agree with Truman's decision not to use nuclear weapons because it could cause a nuclear confrontation with the USSR, which at that time was in the middle of cold war. If the military confrontation had taken place, the third world war would have begun and unleashed catastrophic consequences.
