How much power do drug cartels have in Mexico?

Mexican forces successfully eliminated Nemesio Ruben Oseguera Cervantes, known as 'El Mencho,' the leader of one of Mexico's most powerful drug cartels on February 24, 2026, as part of the nation's decades-long struggle against organized crime. This high-profile takedown triggered a wave of violence across the country, highlighting the significant influence and retaliatory capabilities of criminal organizations operating within Mexico's borders. The operation against El Mencho represents one of the most significant victories in Mexico's ongoing battle against drug cartels, which have plagued the country for decades. The targeted cartel, Jalisco New Generation Cartel (CJNG), is considered one of Mexico's most violent and powerful criminal organizations, extending its operations beyond national borders throughout Latin America. The aftermath of El Mencho's killing has raised critical questions about the future stability of the region and whether this will weaken cartel influence or simply lead to fragmentation and more violent power struggles. According to experts including Sergio Aguayo from the College of Mexico, Chris Dalby author of 'CJNG: A Quick Guide to Mexico's Deadliest Cartel,' and former DEA chief Michael Vigil, the cartels have developed sophisticated networks that infiltrate government institutions, allowing them to maintain remarkable resilience despite constant pressure from authorities.
