Answer:
Who: The Red Scare was primarily fueled by government officials, political leaders, and members of the media who were concerned about the perceived threat of communism in the United States.
What: The Red Scare was characterized by a wave of investigations, arrests, and trials of individuals suspected of being communists or communist sympathizers. Many people lost their jobs, were blacklisted, or were imprisoned on flimsy or false charges. The Red Scare also led to a climate of fear and suspicion, with many Americans spying on their neighbors and reporting them to authorities.
When: The Red Scare began in the late 1940s and continued through the early 1950s, with the peak of the hysteria occurring in 1950 and 1951.
Where: The Red Scare was primarily focused in the United States, but it had global implications as well. The perceived threat of communism led to a heightened sense of tension and rivalry between the United States and the Soviet Union, which were engaged in a Cold War at the time.
Why: The Red Scare was fueled by a number of factors, including the rise of communism in other parts of the world, such as China and Korea, as well as the Soviet Union's acquisition of nuclear weapons. The fear of communist infiltration and subversion in the United States was also stoked by politicians and media figures who saw it as an opportunity to gain political power or advance their careers. The Red Scare was ultimately driven by a deep-seated anxiety about the perceived threat of communism and its potential to undermine American values and institutions.
