Mexico's most aggressive drug trafficking organization, designated a foreign terrorist organization by the United States in February 2025, with operations spanning the Americas, Europe, Asia, and Africa.
Mexico's ground military force, which has served as the primary institution fighting drug cartels since the Mexican government escalated its drug war strategy in 2006.
The primary U.S. agency responsible for combating drug trafficking, which has long pursued El Mencho and CJNG as top-priority targets.
Mexican Army special forces, supported by the National Guard, Air Force, and U.S. intelligence, cornered El Mencho and his security detail near Tapalpa, Jalisco. Oseguera Cervantes was critically wounded in the firefight and died while being airlifted to Mexico City. Six other cartel members were killed and two arrested.
Within hours, CJNG operatives torched vehicles, blockaded highways, and clashed with security forces across Jalisco, Colima, Michoacán, Nayarit, Guanajuato, Tamaulipas, and other states. More than 70 attacks were reported in Guanajuato alone. Prisoners rioted at a Puerto Vallarta lockup, killing a jail guard.
Jalisco Governor Pablo Lemus Navarro declared a statewide red alert, suspending public transportation, canceling schools, and banning large gatherings. Delta, American, Alaska, and Air Canada canceled flights to Puerto Vallarta. The U.S. Embassy issued shelter-in-place advisories for Americans in three states.
The Trump administration designated the Jalisco New Generation Cartel as a foreign terrorist organization and a Specially Designated Global Terrorist entity, citing fentanyl trafficking, extortion, and weapons trade.
Rosalinda González Valencia, known as La Jefa, was arrested in Zapopan, Jalisco and identified as the cartel's financial chief.
El Mencho's son was extradited to face federal charges in Washington, D.C., further isolating the cartel leader from family members who might have succeeded him.
The cartel shot down a Mexican Army helicopter with a rocket-propelled grenade during a security operation in Jalisco, demonstrating military-grade capabilities that few criminal organizations possess.
Cartel gunmen ambushed a state police convoy in Jalisco, killing 15 officers in one of the deadliest single attacks against Mexican security forces in the modern drug war.
Mexican authorities captured Rubén Oseguera González, known as El Menchito and considered the cartel's second-in-command, stripping El Mencho of his closest operational heir.
The cartel dumped 35 bodies of rival Los Zetas members on a Veracruz highway during rush hour, declaring it would "cleanse" the state — a public signal of the organization's ambition and brutality.
Mexican security forces killed Sinaloa Cartel capo Ignacio Coronel in Guadalajara, fracturing the Milenio Cartel. Oseguera Cervantes and Érick Valencia Salazar filled the vacuum by founding the Jalisco New Generation Cartel.

With El Mencho's son, brother, and wife all previously imprisoned, no obvious successor exists. Regional commanders who managed semi-autonomous operations across Mexico begin fighting each other for control of lucrative trafficking corridors, particularly fentanyl routes into the United States. The fragmentation pattern mirrors what happened to the Beltrán-Leyva Organization after its leader was killed in 2009 — the group splintered into at least four competing factions within two years. Violence escalates significantly across CJNG-controlled territory before stabilizing at a new, bloodier equilibrium.
Discussed by: Latin Times, security analysts, and former DEA officials
One of CJNG's senior regional commanders — potentially someone who controlled operations in a critical trafficking corridor — moves quickly to assert authority and prevent fragmentation. This would require both the loyalty of enough armed cells and the logistical capacity to maintain supply chains. The Sinaloa Cartel managed a version of this after El Chapo's 2016 capture, with Ismael "El Mayo" Zambada and El Chapo's sons sharing power. However, CJNG's more decentralized, cell-based structure makes a clean succession less likely than it was for the more hierarchically organized Sinaloa operation.
Discussed by: DEA annual threat assessments, Americas Quarterly, and Mexican security analysts
The Sinaloa Cartel and smaller regional groups exploit CJNG's leadership vacuum to reclaim territory lost over the past decade, particularly in Jalisco, Michoacán, Guanajuato, and the Pacific coast trafficking corridor. This would likely trigger a period of intensified inter-cartel violence as boundaries are redrawn, potentially resembling the nationwide bloodshed that followed the Beltrán-Leyva split from Sinaloa in 2008. The ultimate result would be a reconfigured but not diminished drug trafficking landscape.
Discussed by: Brookings Institution, NPR, and Mexican political commentators
The Trump administration, which has repeatedly proposed sending U.S. troops to Mexico and designated CJNG a foreign terrorist organization, uses the post-operation chaos as evidence that Mexico cannot manage the security situation alone. Washington pushes for greater operational involvement — whether through expanded intelligence sharing, military advisors, or more covert measures — testing the boundaries that President Sheinbaum has drawn around Mexican sovereignty. The retaliatory violence and threats to American tourists provide political cover for escalation.
Colombian security forces, aided by U.S. intelligence and the vigilante group Los Pepes, tracked and killed Medellín Cartel leader Pablo Escobar on a rooftop in his hometown on December 2, 1993. Escobar had been the world's most-wanted drug lord, controlling an estimated 80% of the global cocaine trade.
The Medellín Cartel collapsed almost immediately. The rival Cali Cartel filled the vacuum and dominated Colombia's cocaine market for two years until its own leaders were captured.
Colombia's drug trade didn't shrink — it decentralized. The hierarchical cartel model gave way to dozens of smaller, harder-to-track trafficking organizations. Total cocaine production eventually increased.
The most studied case of kingpin removal in drug war history. Escobar's death eliminated one organization but did not reduce drug supply — it atomized the industry into smaller, more resilient pieces. Mexican officials and analysts cite this precedent when debating whether El Mencho's death will reduce or merely restructure trafficking.
Mexican Marines killed Arturo Beltrán Leyva, head of the Beltrán-Leyva Organization, in a four-hour shootout at his safehouse in Cuernavaca. The operation was considered a major success for President Felipe Calderón's drug war strategy.
The cartel immediately split as top enforcer Edgar Valdez Villarreal challenged Arturo's brother Héctor for control. The internal war produced a wave of violence across multiple states.
Within two years, the organization had fractured into at least four competing factions — the South Pacific Cartel, La Mano Con Ojos, the Independent Cartel of Acapulco, and La Barredora. By 2011, Mexican authorities declared the original organization extinct.
The closest Mexican parallel to El Mencho's killing. It demonstrates that removing a cartel's top leader when no clear succession plan exists can produce rapid, violent fragmentation rather than organizational collapse — the drug trade continues through new, often more violent, structures.
Mexican forces recaptured Sinaloa Cartel leader Joaquín "El Chapo" Guzmán in January 2016 after his second prison escape. He was extradited to the United States in January 2017 and convicted on all charges in February 2019, receiving a life sentence.
An internal succession dispute erupted but was resolved after a rival faction leader was arrested. El Chapo's sons and longtime partner Ismael "El Mayo" Zambada established a power-sharing arrangement.
The Sinaloa Cartel continued operating at near-full capacity. Multi-ton drug shipments continued uninterrupted. The cartel remained the DEA's top-priority target alongside CJNG.
Shows that kingpin removal doesn't always produce fragmentation — if a succession mechanism exists, the organization can adapt. The critical difference with CJNG is that El Mencho's potential successors (son, brother, wife) are all imprisoned, leaving no family-based succession path.
