What caused anxiety in the US after World War 2?

After World War II, anxiety in the U.S. was primarily fueled by the fear of communism and the onset of the Cold War, leading to concerns about national security and the possibility of nuclear warfare. The Red Scare intensified suspicions of communist infiltration in American society, resulting in widespread paranoia and government investigations. Additionally, economic uncertainties and shifts in social norms contributed to feelings of instability and apprehension among the population. The combination of these factors created a climate of fear and anxiety throughout the nation.
