The allies of the US during the Vietnam War were:
South Korea with the second largest contingent fo troops in South Vietnam, Thailand, Australia, New Zealand and the Philippines. Canadian made military hardware was used in Vietnam including large amounts of Agent Orange. The Canadian soldiers that fought in the war were part of the US troops.
After the defeat of the French at Dien Bien Phu, now the US decides not to give any more supply to France and instead divides Vietnam into 2 and orders involvement to protect the capitalist South Vietnam from unification with the communist North Vietnam. Since Vietnam now holds an important strategic position. Successfully protecting South Vietnam not only means the US will be able to prevent the spread of communism but also play a key role in isolating China from the rest of Indochina and US's allies in South East Asia. Holding the ground of Saigon, US is able to save the threat of naval attack of USSR and China to one of the key that locks up the world, Singapore and its ever vibrant strait of Malacca. After Congress passes the Gulf of Tonkin Resolution, US army starts to take direct actions with support of allies' numerous troops from France, South Korea, Khmer Republic, Thailand, Australia, New Zealand and the Philippines. Soviet Union, Democratic People's Republic of Korea and People's Republic of China back up North Vietnam. Later China supports Khmer Rouge in Cambodia. Soon after, Laos is also drawn into war as an ally of North Vietnam.
