In 1948, Korea was divided into two different countries, with South Korea being an anti-communist state supported by American forces, and North Korea being a communist dictatorship closely supported by the Soviet Union and China
The UN forces were made mostly of American troops, but there were also other countries such as Britain who were sent over to fight against the communist North, and they were led by American General MacArthur
The Korean War was the first example where the invasion between East and West were played out in physical conflict, and both superpowers used the conflict to experiment with their new weapons
The United States provided financial aid to France to fight the communists, and in 1954 the French removed their control in Vietnam, which was temporarily divided into North and South
