Introduction: When the World's Most Powerful Drug Lord Falls
On February 22, 2026, the Mexican military eliminated Nemesio Rubén Oseguera Cervantes — alias "El Mencho" — leader of the Jalisco New Generation Cartel (CJNG), the criminal organization considered the largest supplier of fentanyl to the United States. The operation took place in the town of Tapalpa, Jalisco state, western Mexico. El Mencho was injured in the raid and died en route while being transported by helicopter to Mexico City.
This is not merely the death of an individual. This event has the potential to reshape the global drug map, US-Mexico relations, and — something rarely noticed but very real — the daily lives of millions of Vietnamese-Americans and Latino people living in border states.
Mike Vigil, former Chief of International Operations for the DEA (U.S. Drug Enforcement Administration), called this "one of the most significant operations in the history of anti-drug trafficking." He compared El Mencho to Joaquín "El Chapo" Guzmán and Ismael "El Mayo" Zambada — two of the most notorious drug lords in modern history.
However, history also shows: eliminating a cartel leader rarely solves the drug problem. More often, it merely ushers in a new phase of violence.
Context: CJNG — A Drug Empire Built on Fentanyl and Violence
To understand the significance of this event, it's essential to understand what CJNG is. Co-founded by El Mencho and Érick Valencia Salazar (alias "El 85") around 2007, CJNG has grown from a regional organization to become Mexico's most powerful cartel in less than two decades.
CJNG is famous — or more accurately, infamous — for several reasons:
- Extreme violence: CJNG was the first cartel to widely use explosive-laden drones and landmines to attack the Mexican military. In 2020, the organization carried out a spectacular assassination attempt in the heart of Mexico City targeting the city's police chief, using grenades and heavy assault rifles.
- Fentanyl: CJNG has been identified as one of the two main sources (along with the Sinaloa cartel) bringing fentanyl — the synthetic opioid responsible for over 70,000 overdose deaths annually in the U.S. — across the border. Jalisco state, where the cartel's headquarters are located, is a hub for fentanyl production from precursors imported from China.
- Global reach: CJNG operates not only in Mexico. U.S. anti-drug agencies confirm that the cartel has networks in at least 35 countries, including complex transnational money laundering operations.
El Mencho, 59, originally from Aguililla, Michoacán state, has been involved in drug trafficking since the 1990s. Under his leadership, CJNG became Mexico's fastest-growing and most aggressive cartel. The U.S. Department of State had offered a $10 million reward for information leading to his arrest.
The Operation: US-Mexico Cooperation Under Sheinbaum
The most notable aspect of the Tapalpa operation is not its outcome, but how it was carried out. It is the product of US-Mexico intelligence cooperation described as "significantly expanded in recent months" under President Claudia Sheinbaum.
White House Press Secretary Karoline Leavitt confirmed that the United States "provided intelligence" for the operation. A U.S. defense official stated that the U.S. military participated through the Joint Interagency Task Force-Counter Cartel, coordinating with the Mexican military via U.S. Northern Command (NORTHCOM). No U.S. military personnel were present on the ground.
This marks a significant turning point. Under previous president Andrés Manuel López Obrador (AMLO), US-Mexico security relations became severely strained. AMLO pursued a strategy of "hugs, not bullets" (abrazos, no balazos), limiting cooperation with the DEA and at times even refusing to allow U.S. agents to operate on Mexican territory. Sheinbaum — AMLO's successor from the Morena party — agreeing to such extensive intelligence cooperation, leading to El Mencho's elimination, indicates a significant strategic shift in Mexico's security policy.
However, President Trump's reaction highlights the complexity of bilateral relations. Just one day after the operation, he wrote on social media: "Mexico must step up their effort on Cartels and Drugs!" — a statement that could be read as a lack of recognition for the achievement just made by the Sheinbaum administration, or as a political leverage to continue applying pressure.
Deputy Secretary of State Christopher Landau, however, was softer, calling it "a great development for Mexico, the United States, Latin America, and the world.
Post-Operation Chaos: 252 Roadblocks and the Power Vacuum Problem
CJNG's reaction to El Mencho's death was almost immediate and massive. Within hours of the operation:
- 252 road blockades reported across Mexico
- 65 incidents in Jalisco alone — the most nationwide
- 25 National Guard members killed in 6 separate attacks in Jalisco
- Buses and trucks burned on major roads in Guadalajara, Puerto Vallarta, and many other cities
- Puerto Vallarta airport severely affected — passengers ran in panic inside the terminal
- Taxis and ride-sharing services suspended in Puerto Vallarta
- 4 soccer matches postponed
Jalisco Governor Pablo Lemus Navarro activated "red code" — an emergency security protocol — and suspended all public transportation in the state. President Sheinbaum attempted to reassure the public that "most of the national territory is still operating normally," but the reality on the ground showed a completely different picture.
Even more worrying is the violence spreading to neighboring states: Michoacán, Colima, Tamaulipas, Guanajuato, and Aguascalientes. In Reynosa — a border city opposite McAllen, Texas — the cartel blockaded roads to the airport and international bridges. This is an area with very high traffic of Americans.
Mike Vigil explained: the cartel is trying to prove that "they are still a formidable force" and that El Mencho's death "is not a fatal blow." This is a familiar tactic — sowing chaos to display strength — but the scale this time far exceeds any recent precedent.
Lessons from History: The "Hydra Head Effect" and the Endless War
For those following the war on drugs in Mexico, the central question is not whether El Mencho's death is good news — it clearly is — but rather: what happens next? History is not optimistic.
When "El Chapo" Guzmán was last captured in 2016 and extradited to the U.S. in 2017, the Sinaloa cartel did not collapse. It fragmented into factions, leading to a bloody internal war that lasted for years. When Arturo Beltrán Leyva was eliminated in 2009, his organization splintered into at least four smaller groups, each no less violent. Researchers call this the "Hydra head effect" — cut off one head, and more grow back.
For CJNG, the risk of fragmentation is very real. Valencia Salazar — the cartel's co-founder — was arrested by the U.S. in February 2025 in a sweep targeting 29 wanted cartel leaders. CJNG's high-level leadership structure is currently being decimated. This could lead to:
- Internal war within CJNG: Regional commanders vying for power, leading to escalating violence in many areas
- Territorial invasion: The Sinaloa Cartel and smaller organizations may attack CJNG's spheres of influence
- Short-term disruption, long-term recovery: The flow of fentanyl may decrease temporarily but will find new channels — as demand in the U.S. remains unchanged.
This is the core paradox of the "kingpin strategy": it generates short-term political victories but rarely solves the structural problem. Where there is demand, there is supply.
Vietnamese-American Community Perspective: Fentanyl, the Border, and Real Concerns
For the Vietnamese-American community, this event is neither unfamiliar nor irrelevant — though it may seem so at first glance.
Fentanyl and the Asian community: The opioid crisis is often framed as a problem for rural white populations, but recent data shows that overdose death rates in the Asian American community increased by over 150% from 2019 to 2023, according to the CDC. In densely populated Vietnamese neighborhoods in Orange County, San Jose, and Houston, fentanyl is increasingly appearing in drug arrests. CJNG is a primary supplier. Any disruption in the fentanyl supply chain — even temporary — has real practical implications.
Small business owners in border regions: Thousands of Vietnamese small business owners in Texas — especially in the Houston area and the Rio Grande Valley — have cross-border trade relations with Mexico. Reynosa, where the cartel blockaded roads to the airport and international bridges, is opposite McAllen — an important logistics hub. Any prolonged instability at border crossings directly impacts supply chains for goods, from agricultural products to electronic components.
Tourism and personal safety: Puerto Vallarta and Cancún are popular tourist destinations for Vietnamese-Americans, especially during winter. The U.S. Department of State issued a security alert advising U.S. citizens in many Mexican states to shelter in place. Airlines such as Air Canada, Southwest, Alaska Airlines, and Delta have canceled flights to Puerto Vallarta and Guadalajara. For those planning to travel to Mexico soon, this is a signal to monitor closely.
Immigration politics: El Mencho's death will undoubtedly be used by the Trump administration to reinforce arguments for border security. Trump's post urging Mexico to "step up their effort" just one day after the operation indicates he will not let this success pass without political exploitation. This could lead to tighter border control measures — affecting not only Latin American immigrants but also the Asian immigrant community, including Vietnamese people currently undergoing visa or green card processes.
World Cup 2026: The Shadow of Violence Over the Sports Festival
One worrying detail: Guadalajara — the capital of Jalisco, where buses were burned on the streets — is one of the host cities for the 2026 World Cup, scheduled for this summer. The tournament is co-hosted by the U.S., Mexico, and Canada, and Guadalajara is expected to host several matches.
The February 22 event raises serious questions about security. If a military operation can cause 252 blockades nationwide in a few hours, what would happen if cartel violence erupts during the World Cup, with hundreds of thousands of international visitors present in Mexico? FIFA and the organizing committee will face immense pressure to ensure safety.
Looking Forward: Tactical Victory, Strategic Challenge
The elimination of El Mencho is an undeniable security achievement. It is the result of the highest level of US-Mexico intelligence coordination in years, and it sends a clear signal that no cartel leader is invulnerable.
But if history is any guide, the coming months will not be peaceful. The power vacuum within CJNG will trigger a bloody struggle. Rival cartels will seek to expand. Violence in western Mexico could escalate significantly.
And the biggest question remains unanswered: can the United States and Mexico transform this tactical victory into an effective long-term strategy — one that not only decapitates but also addresses the root causes of drug demand and illicit economies? Or is this just another chapter in a half-century-long drug war, where every victory carries the seeds of the next crisis?
For the Vietnamese-American community — those who live, work, and do business in border states, whose children face fentanyl on the streets, who watch immigration policies with anxiety — the answer to this question is not just distant geopolitics. It is a matter of daily life.
