Final answer:
President Kennedy's approach to the Vietnam War would have likely differed from Johnson's, with a focus on covert operations and special forces rather than large-scale military involvement.
Step-by-step explanation:
It is difficult to definitively say what President Kennedy would have done regarding the Vietnam War if he hadn't been assassinated. However, there are indications that his approach would have differed from Johnson's. Kennedy was more cautious and restrained in his actions, and he favored covert operations and special forces rather than a large-scale military involvement. For example, he approved secret bombing raids in Laos and enlisted the Hmong minority to participate in guerilla raids against the North Vietnamese. It is possible that a Kennedy-led Vietnam War would have been less reliant on conventional troops, but ultimately, we can only speculate on what might have happened.
