Which organization is primarily concerned with drug enforcement among U.S. agents overseas?

The Drug Enforcement Administration (DEA) is the primary organization focused on combating drug trafficking and enforcement in the United States, including efforts overseas. The DEA's responsibilities encompass investigating and enforcing the controlled substances laws and regulations within the U.S., as well as coordinating with foreign governments to address international drug trafficking issues. This role extends to conducting operations and intelligence gathering internationally to disrupt drug trade networks.

The DEA has specifically tasked agents stationed abroad to build relationships with foreign law enforcement agencies, share intelligence, and coordinate efforts against drug cartels and trafficking organizations that may operate outside U.S. borders. This includes providing training, resources, and support to enhance the capabilities of foreign law enforcement in tackling drug-related crimes.

The FBI primarily deals with federal crimes including organized crime and domestic terrorism; Customs and Border Protection (CBP) focuses on border security and customs enforcement; and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is involved in enforcing laws related to firearms and explosives, as well as investigating alcohol and tobacco-related crimes.
