What agency has a mission to prevent and deter terrorist attacks while protecting against and responding to threats and hazards to the nation?

• A. US Department of Homeland Security
• B. Federal Bureau of Investigation
• C. Department of Defense
• D. Central Intelligence Agency

Answer: (A)

The agency described is the Department of Homeland Security. Its mission centers on preventing and deterring terrorist attacks while protecting against and responding to threats and hazards to the nation, uniting efforts across border security, transportation security, critical infrastructure protection, and emergency management. After 9/11, the United States created DHS to coordinate these activities nationwide, bringing together agencies like FEMA, the Transportation Security Administration, the U.S. Coast Guard, and others to protect the homeland and lead disaster response and recovery. This integrated focus on both prevention and rapid response to emergencies at home sets DHS apart from agencies with more narrow or different roles, such as the FBI (primarily law enforcement and counterterrorism within the U.S.), the Department of Defense (military defense), or the CIA (foreign intelligence).
