Explain why the USA became increasingly involved in the war in Vietnam?
Vietnam is in the region on Indo-China and as the French lost the Second World War and because of that the Japanese became involved because they were trying to help the French. Ho Chi Minh was the leader of Vietnam, who was a communist, who formed the Vietminh.
In 1949 the USSR exploded an atom bomb, which made the Americans feel very scared and threatened, because now the USA was no longer the only nuclear power, because of that china became communist which made the USA spend $2 billion supporting anti communists. As a result of that the president of Vietnam, Truman Doctrine, came up with containment, so the USA was going to contain the spread of communism. The French were giving money ($500 million) to America on the French war effort.
The French continued to give money to the Americans, this lead to Diem Biem Phu, which was when the French fort the Americans but lost badly, but as a result of that the Geneva Piece Agreement happened which was when Vietnam got devised into two sections, north Vietnam (Ho Chi Mihn was the leader) and south Vietnam (Ngo Dinh Diem was the leader) and because of that they were supposed to have elections about Ho Chi Mihn and Diem but they didn’t happen because of that Eisenhower came up with the domino theory, which was if one country turned communist then the others would that were around it, then it would eventually spread across Cambodia, Laos and eventually Europe. As a result of that America supported Diem by sending money supplies and military equipment because they were scared of what was going to happen.
