Explanation:

In the 1950s, during the cold war, there was an intense anti-communist policy in the United States. US Senator Joseph McCarthy instituted a campaign of persecution of communists in US territory that became known as Macartism. McCarthy claimed that in the United States would be thousands of infiltrated communists, Soviet agents acting as spies, articulating some movement against the country.

The rise of McCarthyism was influenced by the heightened concern of Americans about foreign enemies infiltrating the US government.
