GCSE History covers, amongst other things, the Cold War, which lasted from the end of World War II until the fall of the Soviet Union. One aspect looked at is the intervention of the USA in the Vietnam War.
The government of the USA, under both Johnson and Nixon, became more and more engaged in Vietnam, believing in the "Domino Theory". They thought that intervention in the war was justified because, if South Vietnam fell to Communist aggression, then other neighbouring states like Laos, Cambodia and Thailand would fall too.
Explore the Vietnam War, and the intervention of the USA, in this informative quiz.
