What are the differences between the huac and the dhs?

The House Un-American Activities Committee (HUAC) was a congressional committee active from the 1930s to the 1970s, primarily focused on investigating alleged communist influence and subversion in the United States, particularly during the Cold War. In contrast, the Department of Homeland Security (DHS), established in 2003, is a federal agency tasked with protecting the nation from threats, including terrorism and natural disasters, and managing Immigration and border security. While HUAC was concerned with ideological loyalty and anti-communism, DHS focuses on a broad range of security and safety issues in contemporary society. Additionally, HUAC operated through public hearings and investigations, often leading to accusations and blacklisting, whereas DHS functions as an executive agency with a mandate to coordinate national security efforts.
