Who was in charge of th Red Scare?

The Red Scare, particularly the second one that occurred after World War II, was largely driven by U.S. government officials, most notably Senator Joseph McCarthy. McCarthy led a campaign against alleged communists in the government and other sectors, promoting fears of communist infiltration. The House Un-American Activities Committee (HUAC) also played a significant role in investigating and prosecuting suspected communists. This period was characterized by widespread paranoia and the suppression of dissenting political views.
