At the end of World War II Military and Political tensions between the USSR (Russia) and the US greatly increased. Communism in the USSR presented itself as a big threat to the US’s national security. Fearing that the Communism would spread to Vietnam and other countries, the US opposed the independence movement there.
The US first began by financially supporting France in the first Indochina War. The French defeat in Dein Bien Phu led to a peace conference in Geneva. This conference resulted in splitting the former French colony Indochina into three separate countries, Cambodia, Laos and Vietnam. Vietnam was divided at the 17th parallel into the Communist North and anti-Communist South.
There was a plan for a nationwide election to unify North and South Vietnam. However, in 1956, South Vietnam backed by the US refused to hold the election. The US supported South Vietnam by sending 2,000 military advisors-which grew to over 16,000 by 1963. In 1960, the National Liberation Front (Viet Cong) began to attack the South Vietnamese government.
After two attacks on U.S Navy vessels, the Gulf of Tokin Resolution was passed by the US Congress to give the US more powers to fight the war in Vietnam. The first US Combat troops were sent a year and a half after it was passed. In 1968 over 540,000 troops were in the countries of Vietnam. That same year the Viet Cong launched a massive surprise attack. This is now known as the “Tet Offensive”. This attack threatened the US’s position in South Vietnam. This had a huge impact on the outcome of the war.
President Richard Nixon proposed the “Vietnamization” project. It gave South Vietnam more responsibility in fighting the war while still receiving American aid. The US would also provide air and naval support if necessary. In 1972 the Easter Offensive made people think if the policy was effective. They were suggesting that South Vietnam could not wage a full scale war
