Eisenhower sent troops to South Vietnam so they can fight North Vietnam because North Vietnam wanted to take over South Vietnam and they did.
Eisenhower had US personnel present in South Vietnam to help the transition of French withdrawal in 1954; when they were gone, he promptly dispatched US troops to bolster South Vietnamese defenses in 1955.
As the fighting intensified between the Vietcong and the South Vietnamese army, President Eisenhower sought to support South Vietnam by providing military aid and financial assistance. He also increased the number of military advisors in the region, sending over 600 U.S. personnel to assist the South Vietnamese forces. Eisenhower's administration aimed to bolster the South Vietnamese government in its fight against communism, reflecting the broader U.S. policy of containment during the Cold War.
Eisenhower believed in sending troops, Kennedy did not.
President Eisenhower sent military advisors and maybe some technicians to Vietnam to help the government there stay in power. That was the beginning of US involvement there.
Dwight Eisenhower sent the first advisers to Vietnam. John F Kennedy sent the first US Green Berets to Vietnam. We could've not have to worry about the Vietnam but the US signed a document saying that the US will help with war with communism without hesitation.
Somewhat democratic South Vietnam was a member of the South East Asia Treaty Organization (SEATO), so by treaty, we were obligated to help defend South Vietnam. We entered the Vietnam War to help South Vietnam stop Communist North Vietnam from their attempts to unify the whole country.
To try and keep South Vietnam from falling to the Communists, and because the government of South Vietnam was too corrupt and incompetent to defend themselves. The government of South Vietnam was never able to defend themselves, and President Gerald R. Ford finally gave up on them in 1975. They soon fell to communist North Vietnam.
The government of South Vietnam requested military advisors from the United States to help train the South Vietnamese army. Ho Chi Minh was a communist and during the Cold War of the 1950s and 60s, the aim of the US government was containment of communist power and not to let it spread. The Eisenhower administration provided South Vietnam with money and military advisors (not officially called troops) to help stop the threat of a North Vietnamese takeover. The United States also was pledged by treaty (SEATO) to aid the member nations in southeast Asia, if they were attacked by a foreign (communist) power.
South Vietnam NEEDED help each year. The problem NEVER got better. It just grew and grew.
?........the Vietnam war was a war between north and south Vietnam and America. America was trying to defend south Vietnam from the north invading and controling their territory. so America was on the side with south Vietnam
Eisenhower: sent military advisers to help prop up the non-communist government.Kennedy: sent in 16,000 advisers and helped plot a coup to obtain a more favorable government..Johnson: gradually escalated the situation into full-scale war.Nixon: extended the war into Cambodia and Laos but gradually reduced US troops in Vietnam from 500,000+ to 25,000 while helping train south Vietnamese troops to replace them.Ford: negotiated a truce which allowed most Americans to get out, but allowed North Vietnam to takeover the South,
