John F. Kennedy's actions in Southeast Asia set the stage for future conflict in numerous ways. The most notable example of this was his support of the South Vietnamese government during the Vietnam War. Kennedy provided military and economic aid to South Vietnam, while also sending in military advisers to help the country fight against the North Vietnamese forces. This action, while necessary to protect South Vietnam, had the effect of further deepening the divide between North and South Vietnam, and escalating the conflict.
Additionally, Kennedy's support of the American-backed coup in South Vietnam in 1963, which overthrew the Diem government, further destabilized the region. This coup led to further violence and unrest, and ultimately led to the Vietnam War. Kennedy’s actions in Southeast Asia also contributed to the Cold War, as the conflict between North and South Vietnam became a proxy war between the United States and the Soviet Union.
Ultimately, Kennedy’s actions in Southeast Asia set the stage for future conflict by deepening the divide between North and South Vietnam, and escalating the conflict between the two sides. His support of the coup in South Vietnam also contributed to the unrest and violence that ultimately resulted in the Vietnam War. Lastly, Kennedy’s actions helped to bring about the proxy war between the United States and the Soviet Union
