to keep indochina from going communist. It was part of the domino theory
North Vietnam/VC vs allies
In Vietnam, which is a medium-sized country to the south of China. Vietnam was divided into two countries, North Vietnam, which was Communist, and South Vietnam, which was a highly unstable Capitalist dictatorship. The worst of the fighting happened down at the southern end and involved the Americans and communist rebels in the south, who were known as the Viet Cong. There was also plenty of fighting on the border.
The US and North Vietnam .
Europe had the North Atlantic Teaty Organization (NATO), Asia had the South East Asia Treaty Organization (SEATO). The allies fighting in Vietnam were part of SEATO.
Central Powers= They are the countries that are fighting in the war. Neutral powers= They are not involved in the fighting
Not in Vietnam they weren't. Maybe in some other parts of the world.
The fight against the spread of Communism.
The Soviet Union (USSR) supplied North Vietnam, and the US fought for South Vietnam.
The countries that were actually "physically" involved, and were bombed or had US aircraft crash into them, whether they were "officially" in the war or not, were: Lao's, Cambodia, North Vietnam and South Vietnam.
Nobody knows. Too bad.
The main countries involved were Germany, fighting against Britain, USA,Canada and many other smaller Allies.
Red China/USSR supplied North Vietnam with material & South Vietnamese guerrillas called the Viet Cong supplied guerrillas in the fighting in South Vietnam. The US, Australia, New Zealand, S. Korea, S. Vietnam, Philippines, and Thailand supplied troops for the allied side during the war.
