El Mencho’s Fall Reshapes the U.S.-Mexico Security Pact

Mexico killed Nemesio Oseguera Cervantes, aka El Mencho, the head of the Jalisco New Generation Cartel, in a raid aided by U.S. intelligence—an operation that signals a shift toward a tougher security posture under President Sheinbaum and highlights Washington’s growing role in Mexico’s drug-war efforts. The move reflects the pressure from Trump’s threats of intervention, even as analysts warn the violence may intensify and raise questions about the state’s capacity to manage the fallout and sovereignty.
