Who is highest homeland security cia dea or FBI?

The agencies you mentioned—Homeland Security, CIA, DEA, and FBI—serve different functions within the U.S. government. The Department of Homeland Security (DHS) oversees national security, focusing on domestic threats and emergencies. The CIA primarily handles foreign intelligence and espionage, while the DEA enforces drug laws. The FBI is a federal investigative agency that also deals with domestic intelligence. Each agency has its own jurisdiction and authority, making it difficult to rank them in terms of "highest."
