Why were the American suspicious?

Americans were suspicious due to various factors, including the influence of Propaganda, the fear of communism during the Red Scare, and the perceived threat from foreign powers. Events such as the Cold War, espionage cases, and political tensions heightened these concerns. Additionally, societal changes and civil rights movements prompted skepticism about government intentions and transparency. This atmosphere of distrust often led to heightened scrutiny of both domestic and international affairs.
