What best describes the reason for US involvement in Japan, Korea, and Vietnam was the permanent intent of the United States government to instill the foreign policy of containment during the Cold War years. During that time. the Soviet Union tried to spread Communism over different parts of the world, as was the case of Czechoslovakia, EastmGermany, Poland, Romania, Bulgaria, Hungary, North Korea, North Vietnam, and the Island of Cuba.
That is why the United States tried to impede the spread of Communism at all costs because it went against the economic and political interests. The US attempt to contain Communist influence in Asia and Southeast Asia.
During the Cold War years, the US and the Soviet Union competed in the arms race, the space race, and the spread/containment of Communism.
