Mexican Drug War

The Mexican Drug War refers to the protracted, low-intensity armed conflict between the Mexican federal government and a shifting constellation of drug trafficking organizations (DTOs), as well as violent clashes among the cartels themselves. While drug trafficking in Mexico predates the conflict by decades, analysts generally mark its beginning in December 2006, when President Felipe Calderón deployed the Mexican Army to his home state of Michoacán in Operativo Conjunto Michoacán, militarizing what had previously been a law-enforcement matter.

Key actors have included the Sinaloa Cartel, Los Zetas, the Gulf Cartel, the Jalisco New Generation Cartel (CJNG), La Familia Michoacana, the Knights Templar, and the Beltrán Leyva Organization, alongside the Mexican Army, Navy (SEMAR), Federal Police, and since 2019 the National Guard created under President Andrés Manuel López Obrador. The United States has supported Mexican efforts primarily through the Mérida Initiative, a security cooperation framework launched in 2008 and replaced in 2021 by the Bicentennial Framework.

The conflict has produced extraordinary violence. Mexican government and academic tallies place homicides linked to organized crime in the hundreds of thousands since 2006, with more than 100,000 people registered as disappeared. High-profile episodes include the 2014 disappearance of 43 Ayotzinapa teaching students in Iguala, Guerrero; the 2019 Culiacanazo, in which security forces released Ovidio Guzmán after cartel gunmen overwhelmed the city; and his recapture in January 2023.

Policy debate centers on whether militarized confrontation, "kingpin" strategies, decriminalization, or hugs-not-bullets (abrazos, no balazos) approaches reduce violence. The conflict also raises issues of human rights (forced disappearances, extrajudicial killings documented by the UN and IACHR), arms trafficking from the United States, and the fentanyl trade, which has driven renewed U.S. pressure and 2025 U.S. designations of several cartels as Foreign Terrorist Organizations.
