Which conflict is associated with President JFK's increased commitment of U.S. forces in Vietnam?

The conflict associated with President John F. Kennedy's increased commitment of U.S. forces in Vietnam is the Vietnam War. During his presidency, especially from 1961 to 1963, Kennedy escalated U.S. involvement in Vietnam as part of a broader effort to contain communism during the Cold War. This included sending military advisors and support to the South Vietnamese government in its fight against the communist Viet Cong and North Vietnam. The increased presence of U.S. forces and resources marked a significant shift in American policy, as it moved from providing limited assistance to becoming directly involved in combat operations, ultimately leading to a larger military engagement after Kennedy's assassination.

The Cold War provides the overarching context of tension and rivalry between the U.S. and the Soviet Union, which influenced U.S. foreign policy decisions, but it does not refer specifically to the Vietnam conflict. Similarly, the Gulf War and Korean War are separate conflicts that occurred in different periods and contexts, unrelated to the decisions made during Kennedy's administration regarding Vietnam.
