Which agency is designated as the lead for domestic terrorism and WMD incidents?

The Federal Bureau of Investigation (FBI) is designated as the lead agency for addressing domestic terrorism and incidents involving weapons of mass destruction (WMD). This designation stems from the FBI's broad jurisdiction and expertise in handling criminal investigations related to terrorism. The FBI coordinates intelligence, law enforcement efforts, and response strategies with other agencies at both federal and local levels, ensuring a unified approach to combating domestic threats.

The FBI's role includes not only prevention and response to terrorist acts but also intelligence gathering, analysis, and facilitating interagency collaboration. This agency operates under the broader framework of national security and works closely with other governmental bodies, including the Department of Homeland Security, to improve preparedness and resilience against potential threats.

While the Central Intelligence Agency (CIA) focuses more on foreign intelligence and threats outside the United States, the Drug Enforcement Administration (DEA) is primarily concerned with combating drug-related offenses. The Department of Homeland Security (DHS), while it does play a significant role in overall national security and emergency management, is not designated as the lead agency for domestic terrorism and WMD incidents specifically.
