Mexico Treads a Narrow Path as Trump's Talk of Striking Cartels Intensifies

Mexican President Claudia Sheinbaum is under growing pressure as U.S. President Donald Trump sharpens his language about striking drug cartels, coming after Washington's military operation in Venezuela and the capture of Nicolás Maduro. Among his remarks was a Fox News interview in which he said the United States would begin "hitting land" against cartels.

Similar rhetoric has been heard before, but Mexican officials say it carries different weight now that the United States has shown it will use force in Venezuela. The shift has stoked fears in Mexico that it could be the next target.

The two presidents spoke by phone on Monday. According to Sheinbaum, Trump once again proposed sending U.S. troops into Mexico, and she turned the offer down. She instead pointed to what she called concrete results of joint work: a 50% drop in fentanyl crossing into the United States over the past year and a 43% decline in overdose deaths.

Trump also asked where Mexico stands on Venezuela. Sheinbaum said she answered by citing Mexico's constitution. "I told him that we have a constitution, that we are against military interventions," she said in Spanish, adding that Trump acknowledged those limits.

In Washington on Wednesday, Reps. Joaquin Castro of Texas, Sara Jacobs of California and Greg Stanton of Arizona introduced the No Unauthorized War in Mexico Act, which would bar taxpayer money from being spent on an unauthorized war in Mexico. Stanton said security goals must be pursued in partnership with Mexico and not without congressional authorization. Castro said his San Antonio constituents do not want billions spent on a war that could destabilize the region, spur mass migration and lead to human rights abuses. Jacobs warned that bombing Mexico would not solve the fentanyl crisis and could fuel it, while provoking cartel retaliation against Americans.

Mexican officials told Texas Public Radio that Trump has raised the prospect of deploying troops in every call with Sheinbaum. That pattern has pushed her government to rethink a long-held assumption that deep economic integration and security cooperation would protect Mexico from unilateral U.S. action.

Behind the scenes, Sheinbaum's team has been carefully calibrating its message, defending sovereignty while avoiding words that might invite retaliation, particularly with trade talks and the coming review of the U.S.–Mexico–Canada Agreement (USMCA) approaching. In public, she has stressed continued cooperation against trafficking and highlighted U.S. commitments to address arms smuggling into Mexico, a longstanding Mexican priority. On Tuesday, she warned that foreign interventions have historically harmed Mexico, citing the 19th-century U.S. invasion that cost the country half its territory and calling sovereignty non-negotiable.

Security analyst Cecilia Farfán described Mexico's approach as cautious realism. "Given that the current U.S. administration has publicly discussed carrying out a military strike in Mexico, the best path forward is to assume this is a possibility while actively dissuading it," she said, adding that this stance will likely define Mexico's policy for the next three years. She noted that cooperation appears to be handled through diplomatic channels rather than open confrontation, including talks between Secretary of State Marco Rubio and Mexican Foreign Minister Juan Ramón de la Fuente on fentanyl and firearms trafficking, priorities for Washington and Mexico respectively. "It matters that U.S. statements also mentioned firearms," she said.

U.S. Ambassador to Mexico Ronald Johnson called the Sheinbaum-Trump call "productive" and described the relationship as the most cooperative and mutually beneficial in decades. Trump later questioned the importance of the USMCA, however, showing how quickly cooperation and pressure can coexist. For Sheinbaum, the task is to keep the trade agreement on the table, show measurable security results and hold a firm line against foreign military involvement.
