Increased Security in Jalisco Following Cartel Leader’s Death
Mexico’s navy and military have amplified security measures throughout Jalisco after the death of Nemesio Oseguera Cervantes, the head of the Jalisco New Generation cartel, also known as “El Mencho.” His killing has prompted concerns about potential retaliatory violence and the long-term stability of the region.
In a press release on February 24, Mexico’s Naval Secretariat revealed the arrival of 103 marines and 103 tactical vehicles in Puerto Vallarta aboard the naval ship ARM “Usumacinta” (A-412). This deployment aims to enhance surveillance and security efforts, especially after attacks targeting businesses and infrastructure in nearby areas.
Navy officials mentioned that more personnel—backed by boats, aircraft, and ground vehicles—are being sent out for sea, air, and land patrols in a bid to restore order. This comes swiftly after federal authorities reportedly dispatched around 2,000 additional soldiers to Jalisco state in light of the cartel leader’s death.
The operation against El Mencho, one of Mexico’s foremost drug traffickers, triggered immediate backlash from cartel members, leading to roadblocks, vehicle arson, and confrontations across various states. Mexican authorities view the incident as a significant setback for organized crime, though analysts raise doubts about the efficacy of targeting cartel leaders in attaining lasting peace.
David Mora from the International Crisis Group commented on the situation, stating, “Federal authorities have announced they are increasing military deployments to quell a potentially prolonged cartel backlash.”
After El Mencho’s death, warnings were issued about potential power struggles among remaining leaders of the cartel, as there is currently “no clear successor.” Mora pointed out that such turmoil could intensify turf wars, particularly in Guanajuato and Michoacan states.
The killing of El Mencho may provide a sense of victory for President Claudia Sheinbaum in her dealings with Washington, but Mora cautioned that it remains uncertain whether this will genuinely contribute to pacifying Mexico.
Duncan Wood, a North American Visiting Scholar at the Wilson Center, described the military operation against El Mencho as an assertion of state power. However, he highlighted that the aftermath would largely depend on the cartel’s structure and resilience.
Wood stated, “El Mencho’s removal represents a meaningful assertion of Mexican state power over one of Mexico’s most violent criminal organizations. The ensuing chaos was real, but temporary. In the medium term, the focus will shift to the resilience of CJNG’s decentralized cells and the ability of the Mexican government to maintain a comprehensive security strategy.”
The Mexican embassy has confirmed that heightened security measures remain in effect in certain areas and that authorities are coordinating with international partners to ensure safety at airports and popular tourist destinations. As for the future, there’s still uncertainty about whether this military presence can stave off a wider escalation in violence, given the ongoing rivalries within the cartels and potential clashes.
