Step-by-step explanation:
In the 1940s and early 1950s, there was a fear of communism in the United States, which led to several events and actions. One of the significant events was the victory of Communist forces in China and the outbreak of the Korean War in 1950, which created a political climate where few leaders wanted to be seen as soft on Communism.
This fear also resulted in investigations and interrogations carried out by the government to identify and eliminate any communist sympathizers or spies. For example, the Second Red Scare in the 1950s led to the persecution of people suspected of being affiliated with the Communist Party.
