Which federal agency's main focus includes protecting the nation from terrorist threats?

The Department of Homeland Security (DHS) is fundamentally designed with the primary mission of protecting the nation from terrorist threats and enhancing the nation’s security. Established in the aftermath of the September 11 attacks in 2001, DHS encompasses a wide range of responsibilities aimed at safeguarding the United States from various hazards, including terrorism.

Central to its mission is the focus on preventing terrorist attacks, which includes intelligence gathering, threat assessment, and the creation of policies and programs to mitigate risks. DHS leads efforts in coordinating federal, state, and local responses to prevent terrorism, which include initiatives like the National Terrorism Advisory System and various critical infrastructure protection strategies.

While other agencies like the Federal Bureau of Investigation also play significant roles in counterterrorism efforts, their focus is narrower, primarily centered on investigative and law enforcement activities rather than the broad spectrum of homeland security and preparedness initiatives spearheaded by DHS. Similarly, the National Guard and the Department of Justice have critical roles in national security and law enforcement but do not have the overarching responsibility for protecting against terrorist threats as their main focus like the Department of Homeland Security.
