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

The FBI has been designated as the lead agency for domestic terrorism and Weapons of Mass Destruction (WMD) incidents due to its extensive experience in investigating and responding to domestic threats. The FBI operates a dedicated team for counterterrorism efforts, which includes identifying, preventing, and responding to acts of domestic terrorism. This agency is equipped with the necessary resources, intelligence capabilities, and investigative authority to handle such incidents effectively.

In addition to its investigative role, the FBI collaborates with other local, state, and federal agencies, ensuring a coordinated approach to addressing and mitigating threats related to domestic terror and WMD. Their focus on intelligence gathering and analysis enables the FBI to work proactively to deter terrorist plots and to respond swiftly if incidents occur.

The other agencies mentioned have different primary functions. The CIA primarily focuses on international intelligence and national security issues, the DEA is concentrated on drug enforcement, and the DHS is more involved with overall homeland security and coordination across various threats but does not lead investigations specifically into domestic terrorism and WMD incidents.
