Mexico’s Security Landscape Shifts After ‘El Mencho’s’ Death: A New Era of Violence and Cooperation?
The death of Nemesio Oseguera Cervantes, known as “El Mencho,” leader of the Jalisco New Generation Cartel (CJNG), has triggered a wave of violence across Mexico, resulting in the deaths of at least 25 National Guard troops in Jalisco alone. This event marks a significant turning point in Mexico’s security strategy and raises questions about the future of the country’s fight against drug trafficking and organized crime.
Immediate Aftermath: Violence and Roadblocks
Following the military operation that killed El Mencho, cartel members responded with widespread violence, blocking roads and setting vehicles ablaze across 20 states. Several states canceled school on Monday as authorities worked to clear over 250 roadblocks. The U.S. Embassy issued shelter-in-place orders for personnel in multiple cities, including Puerto Vallarta, highlighting the escalating security concerns.
Increased U.S.-Mexico Cooperation
The successful operation against El Mencho is being hailed as a result of intensified U.S.-Mexico counter-cartel cooperation. A source briefed on the operation indicated a “synergy of efforts,” with Mexican special forces executing the mission while U.S. Personnel provided intelligence and operational advising. This collaboration underscores a shift in strategy under the current administrations, with increased intelligence sharing through joint interagency channels.
A New Security Strategy Under Claudia Sheinbaum
The downfall of El Mencho represents a major achievement for President Claudia Sheinbaum’s administration and her Secretary of Security and Citizen Protection, Omar García Harfuch. This marks a departure from the previous “hugs, not bullets” policy, embracing a more confrontational approach towards criminal groups. The CJNG, notorious for trafficking fentanyl, methamphetamine, and cocaine, had become one of the fastest-growing and most ruthless criminal networks in Mexico.
The Human Cost: Beyond the Cartel Leader
The violence following El Mencho’s death extended beyond clashes with the military. A prison guard, an agent from the state prosecutor’s office, and an unidentified woman were as well killed. In addition to the 25 National Guard troops killed in Jalisco, four more suspects were killed in Michoacan, bringing the total confirmed deaths to at least 33. The disruption also impacted civilians, with over 1,000 people stranded overnight in Guadalajara’s zoo due to the violence.
Potential for Increased Violence and Fragmentation
Experts warn that El Mencho’s death could lead to further violence as rival cartels attempt to exploit the CJNG’s weakened state. David Mora, a Mexico analyst for International Crisis Group, suggests that other criminal groups may see an opportunity to expand their control and gain territory previously held by the CJNG. This fragmentation could lead to a more chaotic and unpredictable security landscape.
Diplomatic Implications, and U.S. Pressure
Mexico hopes that the success against El Mencho will alleviate pressure from the U.S. To do more to combat drug trafficking, particularly fentanyl smuggling. Former President Trump has repeatedly called for Mexico to increase its efforts, threatening tariffs or unilateral military action. The operation has already received positive recognition from the U.S. Ambassador, Ron Johnson, who praised the bilateral cooperation.
The CJNG: A Cartel Unlike Others
The Jalisco New Generation Cartel distinguished itself through aggressive tactics, including attacks on the military and the employ of explosives and drones. In 2020, the cartel launched a brazen attack in Mexico City against the then head of the capital’s police force, demonstrating its reach and audacity. The cartel was designated as a foreign terrorist organization in February 2025.
