A ferocious backlash swept across Mexico this week — with torched vehicles, highway blockades, burned bank branches and suspended school classes in more than a dozen states — after security forces killed Nemesio Oseguera Cervantes, better known as “El Mencho,” the head of the Jalisco New Generation Cartel.

As Bloomberg reported, the takedown of one of the country’s most powerful crime bosses triggered an immediate and violent response. Tourists were stranded in beach destinations like Puerto Vallarta, while cities across multiple regions braced for retaliation. History suggests this pattern is grimly familiar: when a cartel kingpin falls, reprisals against the state are often followed by bloody internal power struggles as lieutenants scramble to fill the void.

The killing of El Mencho marks a defining moment for President Claudia Sheinbaum, whose administration authorized the operation against the Jalisco New Generation Cartel (CJNG), widely considered Mexico’s most formidable criminal enterprise. As Bloomberg reported, the cartel generates billions of dollars annually from drug trafficking, extortion and other illicit ventures, making it a central pillar of the country’s underworld economy.

The move carries enormous risks. Mexico has seen how removing a cartel chief can ignite sustained instability — as happened in Sinaloa after the 2024 removal of Ismael “Mayo” Zambada. Yet Bloomberg reported that Sheinbaum’s decision also represents a sharp departure from her predecessor’s softer security posture.

Under former President Andrés Manuel López Obrador — known as AMLO — the government embraced a controversial “hugs, not bullets” approach. In 2019, López Obrador halted a military operation and ordered the release of a son of Joaquín “El Chapo” Guzmán to avoid bloodshed. By contrast, Sheinbaum has intensified security cooperation with the United States, leading to high-profile extraditions, major drug seizures and crackdowns tied to CJNG-linked networks.

This latest operation, reportedly supported by U.S. intelligence, underscores deepening bilateral coordination at a time when President Donald Trump — has increased pressure on Mexico to rein in cartel violence. Trump previously designated CJNG as a foreign terrorist organization, elevating the stakes for Mexico’s security response.

El Mencho was not a symbolic target. He commanded what amounted to a private army, survived repeated attempts to capture him and allegedly orchestrated brazen attacks — including a 2020 assassination attempt on Omar García Harfuch, then Mexico City’s security chief. His organization expanded aggressively across territories and diversified its criminal portfolio, cementing its dominance.

Still, the so-called “kingpin strategy” has a mixed record. Removing a cartel boss rarely dismantles the structure beneath him. Criminal networks — like any multibillion-dollar enterprise — adapt quickly to leadership vacuums. Bloomberg reported that while the state’s show of force may deter some rivals, it could also unleash factional warfare in contested regions.

Politically, the moment is delicate for Sheinbaum. Insecurity consistently ranks as Mexicans’ top concern, according to polling cited by Bloomberg, and her Morena party has faced scrutiny over alleged ties between some local officials and criminal groups. The operation may strengthen her hand domestically by signaling resolve, while also easing U.S. pressure for more aggressive cross-border intervention.

At the same time, Sheinbaum now walks a tightrope. Her party long criticized the hardline tactics of former conservative President Felipe Calderón, whose militarized anti-cartel campaign drove homicide rates sharply higher. By adopting a similarly forceful approach, Sheinbaum risks internal political friction if violence escalates.

For months, President Trump has argued that cartels exert outsized control in Mexico, publicly challenging the country’s sovereignty claims. Sunday’s operation complicates that narrative, demonstrating that Mexico’s government retains the capacity to strike at even its most entrenched criminal leaders.

The immediate aftermath may bring turbulence. But strategically, the message is unmistakable: the era of restraint has given way to confrontation. Whether this recalibrated strategy restores order — or deepens the cycle of bloodshed — will define Sheinbaum’s presidency and reshape Mexico’s security landscape for years to come.
