Difference between homeland security and FBI?

Homeland Security is a broad federal department focused on protecting the United States from various threats, including terrorism, natural disasters, and border security. It encompasses multiple agencies, including the Federal Emergency Management Agency (FEMA) and the U.S. Customs and Border Protection. In contrast, the FBI (Federal Bureau of Investigation) is a specific agency under the Department of Justice that primarily investigates and enforces Federal Laws, with a strong emphasis on counterterrorism, cybercrime, and criminal investigations. While both work to ensure national security, their scopes and responsibilities differ significantly.
