Why did the US fear the spread of communism?

The production and distribution of products are entirely under the authority of the government. Americans are concerned that the rise of Communism poses a danger to their liberties, uniqueness, and way of life. Because free business and the capitalist system were the cornerstones of the American economy and, by extension, the American way of life, the United States felt endangered by the development of communism.

The U.S. government was concerned throughout the Cold War that communism would expand and endanger democracy worldwide. In order to fight communism in Vietnam, the United States initially offered financial support to South Vietnam, which strove to align Vietnam with western allies like the United States.
