The Day After the Kingpin Fell: Chaos, Succession, and the Future of the CJNG Post-Mencho
Nemesio "El Mencho" Oseguera Cervantes is dead. But as smoke clears over Guadalajara, a terrifying new reality sets in. This is the definitive guide to the violent power vacuum now threatening the stability of Mexico and the security of the 2026 World Cup.

Chapter 1: Anatomy of the Retaliation
The cartel's response was not subtle; it was an orchestrated display of paramilitary force designed to terrorize the population and paralyze government response. The tactic is known as narcobloqueos (narco-blockades).
Within an hour of the news breaking, armed commando units hijacked city buses, cargo trucks, and private vehicles across the Guadalajara metropolitan area. They parked them horizontally across major arteries—including the highways to the airport and the tourist hub of Puerto Vallarta—doused them in gasoline, and set them ablaze.
- Civilians Caught in the Crossfire: Thousands of commuters were stranded. Social media was flooded with videos of terrified families fleeing their cars as gunmen took control of intersections.
- Economic Paralysis: Businesses, schools, and universities across the state of Jalisco declared an indefinite suspension of activities. The economic toll of a single day of paralysis is estimated in the tens of millions of dollars.
- International Fallout: The US State Department immediately raised its travel advisory for Jalisco and Colima to "Level 4: Do Not Travel," urging all US citizens in the region to shelter in place.
Chapter 2: The FIFA Nightmare – World Cup 2026 at Risk
The timing could not be worse. With the 2026 FIFA World Cup scheduled to begin in just over 100 days, the violence in Guadalajara is a diplomatic catastrophe. The Estadio Akron, a premier venue for the tournament, is located directly in the zone where some of the heaviest blockades occurred.
The Security Dilemma
Mexican authorities are desperately trying to project calm, assuring FIFA that the violence is a temporary "death rattle" of the cartel's leadership. However, behind closed doors, there is panic. How do you guarantee the safety of hundreds of thousands of international tourists when the host city can be locked down by insurgents in a matter of minutes?
Sources close to the situation indicate that FIFA is holding emergency meetings to discuss contingency plans, though moving the matches remains a last-resort option that would humiliate the Mexican government.

Chapter 3: The War for Succession – Consolidation or Fragmentation?
The most critical question facing global security analysts right now is not about the past, but the immediate future: What happens to the CJNG infrastructure? History shows two potential paths when a capo of El Mencho's stature falls.
Scenario A: The Dynastic Succession
The most optimistic scenario for stability is a quick consolidation of power by El Mencho's inner family circle. Attention is focused on his stepson, Juan Carlos Valencia González, known as "El 03." If he can command the loyalty of regional lieutenants, the cartel may continue business as usual, focusing on its highly profitable fentanyl trafficking routes rather than internal warfare.
Scenario B: The Balkanization of the CJNG
This is the nightmare scenario. The CJNG is a vast network of semi-autonomous "plazas." Without El Mencho's unifying iron fist, ambition will likely take over. Powerful regional bosses in states like Michoacán, Veracruz, and Zacatecas may decide to break away, forming their own smaller, hyper-violent cartels.
This "balkanization" would lead to a multi-front civil war across Mexico, as former allies turn their guns on each other to control territory, skyrocketing the national homicide rate and making the security situation vastly more complex for the government.

Final Analysis: A Pyrrhic Victory?
The death of El Mencho is a monumental historical event, closing the chapter on one of the world's most notorious criminals. However, for the people of Mexico and the global community preparing for the 2026 World Cup, the celebration is muted by fear. The state has proven it can kill the king, but the coming weeks will determine if it can survive the kingdom collapsing.
