The Limits of Decapitation: Mexico's Security Outlook After El Mencho

2 Mar 2026 01:17 PM

After the takedown of the head of the organised crime group Cartel Jalisco Nueva Generación (CJNG), one thing is certain: ordinary Mexicans are set to pay the price as violence escalates.

Pedestrians walk past charred buses that were set on fire in Guadalajara, Mexico, 22 February, 2026, after the death of the leader of the Jalisco New Generation Cartel, Nemesio Oseguera Cervantes, known as 'El Mencho'.

On 22 February, Mexico’s federal security forces killed Nemesio Rubén Oseguera Cervantes (alias El Mencho), the leader of the Cartel Jalisco Nueva Generación (CJNG) – one of Mexico’s most powerful and violent criminal groups – after locating and targeting his hideout in an ecotourism resort in Tapalpa, Jalisco state.

The operation was supported by intelligence provided by the US authorities, which had previously offered a $15 million bounty for Oseguera Cervantes’ capture. Despite the lack of direct participation of the US on the ground, President Donald Trump has claimed credit for the takedown.

The ‘kingpin’ strategy of targeting cartel leaders has been a long-favoured approach by the US to ‘weaken, dismantle and destroy’ drug trafficking organisations, as part of its ‘War on Drugs’. However, such methods have a poor track record in Latin America, tending to drive fragmentation, competition and violence while illicit markets themselves remain intact.

Indeed, what comes next – both for the CJNG, and for Mexico’s criminal ecosystem more broadly – beyond the initial wave of retaliatory violence is far from clear.
