The correct answer to this open question is the following.
Kennedy’s actions in Southeast Asia set the stage for future conflict because, in 1961, John F. Kennedy sent military Special Forces to South Vietnam to train the South Vietnamese troops, as the US tried to support South Vietnam in its fight against North Vietnam. Let's remember that the Soviet Union was supporting North Vietnam to spread Communism in the region and the United States supported South Vietnam to stop the spread of Communism.
