The conflict of ideologies between the communist government of North Vietnam and the capitalist backed government of South Vietnam stemmed from a difference in political systems and fear. During WW II the United States allied with Vietnamese leader Ho Chi Minh to push the army of the Japanese Empire from Vietnam, a French colony. However, once the Japanese and Germans were defeated. The US found a new enemy in the communist empire of the Soviet Union. As the capitalist countries of the west faced off against the USSR, a war of ideas emerged, a Cold War. At the time, many Americans had strong anti-communist feelings and feared that the Soviet Union wanted to spread their ideology across the globe, including the United States. Indeed, an American envoy to the USSR, George F. Kennan, sent a telegram to Washington D.C. from Moscow stating what he believed to be Stalin’s goal. “…it is desirable and necessary that the internal harmony of our society be disrupted, our traditional way of life be destroyed, the internal authority of our state be broken, if Soviet power is to be secure” (qtd. in Appleby 534-535). Furthermore, the dread that communism might take over the world seemed like a rational fear when China, the most populous nation in the world, fell to communism in 1949. The capitalist-backed leader Chiang Kai-shek was defeated by the communist forces of Mao Zedong (Chiang Kai). Therefore, in 1950 when the Vietnamese, who were now fighting the French as they tried to reestablish their colony, fell under the influence of communism, the United States decided to help France in order to prevent the spread of communism across Southeast Asia. President Eisenhower articulated the danger of communism by comparing Vietnam as the first in a series of nations that, like a row of dominos, would succumb to the influence of communism (Domino Theory). This fear of a different political system was used as the rationale for placing US troops on the ground in Vietnam to battle the communists. Works Cited "Chiang Kai." Chiang Kai.
