The Cold War era included many reforms that occurred internally and externally in relation to the politics of the United States. In terms of domestic conflicts, the anti-communist movement became a major cause of concern for the government. In that way, while the national statement itself called for an open democracy, political parties within the country began objecting to the existing organizational elements of the administration.
Initially, American politicians of Truman’s Democratic Party were accused of pro-Soviet appropriation of communism and related socialist values. Such tensions proceeded with the creation of organizations such as the House Un-American Activities Committee, which regulated the spreading of alleged communist propaganda. The committee members were responsible for reporting on any activities of U.S. citizens that could suggest their disloyalty to their country. The domestic tensions were evidently created by the gradually growing mistrust between fellow citizens and government officials. Eventually, as the Cold War required additional effort for the country to stay united, the Committee was terminated and replaced by the U.S. House Committee on the Judiciary.
In conclusion, the Cold War caused domestic conflict in the United States as a result of major anti-communist movements. At the same time, the formation of House Un-American Activities Committee presented a critical issue of mistrust among American citizens, as disloyalty reports became more common cross-nationally.
