President Claudia Sheinbaum announced "Plan Kukulkan" on 6 March, committing up to 100,000 security forces, 2,500 vehicles, 24 aircraft, anti-drone systems and explosives-detection dogs to secure World Cup venues across Mexico 1. She travelled to Jalisco personally — the state where four group-stage matches will be played in Guadalajara, and the epicentre of retaliatory violence following the military's killing of Jalisco New Generation Cartel leader Nemesio "El Mencho" Oseguera Cervantes on 22 February 2.
The deployment's scale reflects what followed El Mencho's death. At least 70 people were killed in retaliatory violence across at least a dozen Mexican states, with armed clashes and road blockades reported in up to 20 3. Cartel members burned buses and blocked highways in and around Guadalajara itself. The CJNG has been Mexico's most territorially aggressive criminal organisation since the Sinaloa Cartel's internal fracture in 2023, and El Mencho's removal does not dissolve its command structure. Decapitation strikes against Mexican cartels have historically produced succession violence lasting months, not weeks — the 2009 killing of Arturo Beltrán Leyva triggered a prolonged war between his lieutenants, and the Zetas' fragmentation after their leadership was dismantled in 2012-2015 generated years of localised conflict.
Plan Kukulkan's name — referencing the feathered serpent deity of Mesoamerican civilisation — is deliberate political branding. Sheinbaum is staking personal authority on tournament security; a president visiting a violence-wracked state to announce a military operation is a signal directed simultaneously at FIFA, at European governments pressing for safety guarantees, and at domestic audiences. The 100,000-troop figure, if fully realised, would represent a force larger than Mexico deployed for any single security operation in recent memory. Whether the government can sustain that posture across three host cities for five weeks while managing ongoing cartel fragmentation is the operational question FIFA has not publicly addressed. Infantino stated he was "confident" Mexico could co-host safely 4, but that assessment preceded the full scale of post-El Mencho violence.
The practical test arrives in Guadalajara. Four group-stage matches at Estadio Akron will require secure corridors for tens of thousands of international fans in a city where, weeks earlier, cartel operatives were burning public transport on arterial roads. Sheinbaum's government has the military resources; the gap is between a security perimeter around stadiums and the threat environment across entire metropolitan areas. Mexican security forces have experience protecting high-value fixed sites — the 2012 G20 summit in Los Cabos, the 2018 presidential inauguration — but sustaining that protection over a month-long tournament with multiple simultaneous venues is a different operational problem.
