The causes of the Vietnam War were derived from the symptoms, components and consequences of the Cold War. The causes of the Vietnam War revolve around the simple belief held by America that communism was threatening to expand all over south-east Asia.
Neither the Soviet Union nor the United States could risk an all-out war against each other, such was the nuclear military might of both. However, when it suited both, they had client states that could carry on the fight for them. In Vietnam, the Americans actually fought – therefore in the Cold War ‘game’, the USSR could not.

During the 1930s, the combination of the Great Depression and the memory of tragic losses in World War I contributed to pushing American public opinion and policy toward isolationism. Isolationists advocated non-involvement in European and Asian conflicts and non-entanglement in international politics. Although the United States took measures to avoid political and military conflicts across the oceans, it continued to expand economically and protect its interests in Latin America. The leaders of the isolationist movement drew upon history to bolster their position. In his Farewell Address, President George Washington had advocated non-involvement in European wars and politics. For much of the nineteenth century, the expanse of the Atlantic and Pacific Oceans had made it possible for the United States to enjoy a kind of “free security” and remain largely detached from Old World conflicts. During World War I, however, President Woodrow Wilson made a case for U.S. intervention in the conflict and a U.S. interest in maintaining a peaceful world order. Nevertheless, the American experience in that war served to bolster the arguments of isolationists; they argued that marginal U.S. interests in that conflict did not justify the number of U.S. casualties.
