Mexico Is Caught Between Trump and the Cartels

News AnalysisPresident Trump has demanded President Claudia Sheinbaum confront the cartels.

The timing, however, seemed to be telling.President Trump has been loudly and repeatedly demanding that Mexican officials dismantle the cartels that have amassed fortunes by sending drugs across the border. If they don’t, he has threatened, the U.S. military may do the job instead.Those threats appear to be having an effect.President Claudia Sheinbaum of Mexico has overseen one of the most aggressive offensives against the cartels in more than a decade.On Sunday, weeks after Mr. Trump ordered a military intervention in Venezuela and warned that Mexico was next, Ms. Sheinbaum took another bold swing. She authorized Mexican forces to take out her nation’s most wanted criminal, using intelligence provided by the United States.ImageSecurity forces in the historic center of Mexico-city" class="entity-link entity-location" data-entity-id="1779" data-entity-type="location">Mexico City on Monday.

Just as Mr. Trump’s wish to strike Mexico has become a regular part of his rhetoric, so has her refrain about protecting Mexico’s sovereignty.On Monday, she repeated the limits on the American role. “There is no participation of U.S. forces,” she told reporters. “The understanding with the United States is based primarily on the exchange of intelligence.”Ms. Sheinbaum confirmed that U.S. agencies provided intelligence for the operation against Mr. Oseguera, and The New York Times reported Monday that critical information came from the C.I.A.Mexico’s defense secretary also credited American agencies with assistance but said the break in the case came when Mexican intelligence officials identified an associate of one of Mr. Oseguera’s lovers, who then led the authorities to the cartel leader’s hide-out.It is clear the two sides have improved cooperation. In January, the U.S. military set up an intelligence-sharing task force in Arizona, about 15 miles from the Mexico border. The force has roughly 300 military and civilian staff who study the cartels — their leadership, logistics and financial operations — to feed intelligence to the Mexican authorities. The task force aided the raid on Mr. Oseguera, The Times reported.From 2008 to 2023, the United States spent $3.6 billion on bilateral security with Mexico. But it was not always so collaborative. One classified U.S. intelligence program investigated top targets in Mexico but kept the information from the Mexican authorities. That secretive approach was partly validated when numerous Mexican officials were shown to be corrupted by the cartels.John Feeley, a top U.S. diplomat in Mexico from 2009 to 2012, said it appeared the tides were shifting. “The big difference always was that we never had full buy-in from the Mexicans,” he said. The recent successes, he added, “show that, with Mexico at least, the United States needed to bring more pressure to bear to create the moment of political will.”ImageA burned car in Guadalajara, Mexico, a day after the killing of Mr. Oseguera.Credit...Cesar Rodriguez for The New York TimesStill, the Mexican authorities had tried to catch Mr. Oseguera before. In 2012, he escaped when his cartel blocked roads with burning vehicles. In 2015, his gunmen shot down a Mexican military helicopter with a rocket-propelled grenade, killing three soldiers.Those were under more conservative presidents. Under Ms. Sheinbaum’s leftist predecessor and political benefactor, Andrés Manuel López Obrador, Mr. Oseguera appeared to face less pursuit. Mr. Obrador’s “hugs not bullets” approach to solving Mexico’s violence by addressing root causes led to rising violence. It also badly fractured the U.S.-Mexico security relationship.Two cartel bosses were caught under Mr. López Obrador’s watch. The first — Ovidio Guzmán López, a son of El Chapo and a leader of the Sinaloa cartel — was promptly released after his followers wreaked havoc in response to his capture. The second — Ismael Zambada García, or El Mayo, a co-founder of the same cartel — was captured by the American authorities when they persuaded his ally to turn on him and take him to the United States.Ms. Sheinbaum has proved to be a far more willing partner in the fight against the cartels.“The question always was: Is Claudia going to emerge from AMLO’s shadow?” Mr. Feeley said, referring to Mr. López Obrador by his initials. “She has not only emerged, she has cut a level of security engagement from a whole new cloth.”Now that Ms. Sheinbaum has eliminated Mexico’s most wanted cartel boss, will Mr. Trump lay off the threats?On Monday morning — less than 24 hours after arguably Mexico’s biggest achievement in its cartel war in years — Mr. Trump posted a message online for his neighbor: “Mexico must step up their effort on Cartels and Drugs!”Jack Nicas is The Times’s Mexico-city" class="entity-link entity-location" data-entity-id="1779" data-entity-type="location">Mexico City bureau chief, leading coverage of Mexico, Central America and the Caribbean.SKIP
