Vietnam was separated into two sides: North Vietnam and South Vietnam. North Vietnam was pro-communist, and South Vietnam was pro-democracy (anti-communist). North Vietnam's goal during the Vietnam War was to invade and take over South Vietnam to establish a communist government in Vietnam as a whole. South Vietnam was trying to defend its territory. The United States helped South Vietnam because of the Domino Theory, which is that if one country became communist, so will the others around it. The United States helped South Vietnam to try to contain the spread of communism, as they were pro-democracy and anti-communist.
