Explain how the presidents of the 1960s influenced policy on vietnam

There were several different presidents who had to deal with the Vietnam War. Here were their actions:

Kennedy (1960-1963)- attempted to aid South Vietnamese troops by sending a few thousand soldiers. Their goal was not combative, rather it was to support Southern Vietnamese troops with technology and strategy. Ultimately, Kennedy was trying to stop the spread of the communist regime of North Vietnam.

Lyndon B. Johnson (1963-1969) - Due to North Vietnam's progress, Johnson steadily increased the amount of troops to South Vietnam. At one point, roughly 500,000 US soldiers were in Vietnam. Under Johnson, they took on more of a combative role. Johnson's promise of victory being right around the corner never came true and only got American citizens hopes up.
