Both of these presidents wanted to follow a strategy of limited warfare. President Kennedy’s approach to the war was more limited than President Johnson’s because Kennedy came first. During his time in office, Kennedy tried to limit American involvement to non-combat roles. He sent in advisors and support staff such as helicopter pilots. By the time President Johnson had been in office a few months, it was becoming clear to him and his advisors that American involvement had to be increased. Johnson still tried to keep the war limited, though. He did this, for example, by restricting the sorts of targets that American forces could attack. In these ways, both presidents tried to keep American involvement as limited as they could. However, these efforts were largely futile and American involvement continued to grow.
