What actions did the US take to combat the red scare?

During the Red Scare, particularly in the late 1940s and early 1950s, the U.S. government took several actions to combat perceived communist threats. This included the establishment of the House Un-American Activities Committee (HUAC) to investigate alleged communist influence in various sectors, including Hollywood and labor unions. Additionally, Senator Joseph McCarthy led a campaign that resulted in the blacklisting and persecution of individuals suspected of communist ties. The federal government also implemented loyalty oaths for government employees and increased surveillance and Propaganda efforts to promote anti-communist sentiment.
