The Kingpin’s Fall: Mexico’s Cartel War Just Got Deadlier—Here’s What Happens Next

A stunning development rocked Mexico last weekend. The death of the nation’s most notorious drug kingpin, Nemesio Oera Cervantes, better known as El Mencho, has sent shockwaves through both Mexico and the United States. He was the leader of the Jalisco New Generation Cartel (CJNG), a group infamous for its bloody rise to power, its cartel-wide reach, and its involvement in methamphetamine and fentanyl production. However, the aftermath of his death has brought about violence, chaos, and political tension that no one saw coming.

While the Mexican government is still piecing together the details of El Mencho’s death, it is clear that his demise has thrown Mexico into another round of brutal cartel-driven violence. The very same day, more than 70 people were killed, including at least 25 members of Mexico’s National Guard. Immediately following the news, cartel operatives launched a wave of attacks across Mexico, setting up nearly 100 roadblocks and hijacking vehicles. Major airports, including Guadalajara and Puerto Vallarta, were shut down, trapping both locals and tourists—including Americans. There were reports of fires, explosions, and the city streets being empty for hours.

At this moment, the question on everyone’s mind is: What now? What happens to Mexico’s government? And will the death of El Mencho really bring peace to Mexico’s streets, or will it just lead to more bloodshed and instability?

Who was El Mencho, and why was his death so significant?

El Mencho wasn’t born into a life of luxury. He began his criminal career with humble beginnings—starting in law enforcement. In the 1990s, he was arrested in the U.S. for drug trafficking and served a sentence for three years. When he was released, he re-entered the drug business, co-founding the CJNG in 2009. Over the next decade, he transformed this group into one of the most deadly and influential criminal organizations in the world.

The CJNG is a multi-billion-dollar cartel responsible for smuggling meth, fentanyl, and other drugs into the U.S. from various places. Their reach extended to nearly every state in the country, infiltrating the entire world’s drug supply chain. But El Mencho wasn’t just a criminal mastermind—he was also a businessman who sought territory, recruiting thousands of individuals to wage war against rival cartels. To protect his empire, he heavily militarized the CJNG. They had armored trucks, drones, and high-caliber rifles—tools normally reserved for the most elite military forces. The group became more than just a cartel—it evolved into an army.

The Mexican Military Operation

So how did Mexico track down and kill one of the most elusive cartel leaders of all time? The operation, which occurred in western Mexico, started when Mexican intelligence traced El Mencho’s romantic partner. After months of surveillance, authorities were able to piece together the CJNG leader’s movements, and they zeroed in on a secluded safe house in the woods.

The operation took place at dawn, and it was far from quiet. Mexican military personnel surrounded the safe house, but El Mencho’s security opened fire, initiating a bloody firefight. The violence escalated so quickly that a military helicopter had to make an emergency landing. El Mencho managed to flee the safe house and ran into the forest, injured but alive. He was eventually captured, but did not survive long. El Mencho died while being airlifted to Mexico City for medical treatment.

Cartel Chaos in Mexico

While the operation seemed successful on paper, the aftershocks have been far-reaching. After El Mencho’s death, cartel crews immediately retaliated, plunging Mexico into chaos. The Jalisco New Generation Cartel organized widespread violence to retaliate. More than 70 people were killed in the following days, including dozens of National Guard members, and the violence didn’t end there. Hundreds of roadblocks were erected, and entire cities came to a standstill. Guadalajara, a major city, went silent, and airports were forced to suspend flights. Tourists, including Americans, found themselves stranded.

Mexico’s violence was so intense that some cities, particularly those preparing for the 2026 FIFA World Cup, were impacted heavily, leaving tourists to shelter in place and causing economic disruptions across the country. The U.S. Embassy in Mexico issued warnings to Americans about the dangers of traveling or staying in certain parts of the country. Some tourist groups, especially students planning their spring break trips, canceled their travel plans entirely in response to the ongoing violence.

What Does El Mencho’s Death Mean for Cartels?

Although El Mencho may be dead, his cartel is far from finished. The CJNG is not built around one single figure—it is a multi-layered network with deep connections, and history tells us that when one leader falls, another quickly rises to fill the gap. But if a successor doesn’t emerge quickly enough, the cartel will likely fracture into several armed factions. This can lead to more turf wars and violence as gangs fight to take control of the most valuable territories in Mexico.

From the perspective of Mexico’s government, it remains to be seen whether the cartel’s power will collapse or whether a successor will assume control seamlessly. If there is no clear successor, Mexico could be facing months, if not years, of heightened instability as factions battle for dominance.

The Bigger Question: Can Mexico’s Cartels Ever Be Stopped?

To understand how Mexico’s cartels rose to power, we have to rewind the clock to the 1980s, when the Mexico government’s crackdown on drugs only led to more cartel wars, splitting once-dominant cartels into factions. Then, when Mexico declared a war on drugs in 2006, it created a power vacuum—one that fueled even more violence, with cartels fighting for control of territories. This created the perfect environment for groups like the CJNG to rise.

The CJNG’s rise came at a time when Mexico’s law enforcement was overwhelmed, and authorities had difficulty responding effectively. But now, after years of bloodshed, the Mexican state is finally demonstrating strength. The operation to kill El Mencho was a significant achievement, but experts agree that Mexico’s cartels still pose a formidable threat, and the cartel violence in the aftermath proves that Mexico’s government must remain vigilant.

What’s Next for Mexico’s Drug War?

It’s clear that the death of El Mencho does not signal the end of cartel violence in Mexico. While his death is an important symbolic victory, it is unlikely to have any lasting impact on the drug trade or the violence caused by cartels. The real question remains: How can Mexico address the systemic violence that has been woven into its social fabric for years?

The Mexican government’s fight against cartels will continue as the nation battles the long-standing issue of organized crime. The international community, including the U.S., will have to work even more closely with Mexico to disrupt cartels that have a footprint across both nations. As long as cartels continue to operate with impunity, Mexico will likely see more violence.

The violence in Mexico is not just the story of one cartel leader’s death. It is a reflection of the larger challenges that the government faces in cracking down on organized crime. With El Mencho’s death setting off waves of violence and uncertainty, one thing remains clear—Mexico’s drug war is far from over.
