Mexican President Claudia Sheinbaum rejects Trump’s offer of military intervention against cartels

Mexican President Claudia Sheinbaum present a new security strategy against violence for Michoacan state, at the National Palace, in Mexico City, Sunday, Nov. 9, 2025.

MEXICO CITY — Mexico’s president on Tuesday ruled out allowing U.S. strikes against cartels on Mexican soil, a day after U.S. President Donald Trump said he was willing to do whatever it takes to stop drugs entering the U.S.

“It’s not going to happen,” President Claudia Sheinbaum said.

“He (Trump) has suggested it on various occasions or he has said, ‘we offer you a United States military intervention in Mexico, whatever you need to fight the criminal groups,’” she said. “But I have told him on every occasion that we can collaborate, that they can help us with information they have, but that we operate in our territory, that we do not accept any intervention by a foreign government.”

Sheinbaum said she had said this to Trump and to U.S. Secretary of State Marco Rubio on previous occasions and that they have understood.

“Would I want strikes in Mexico to stop drugs? OK with me, whatever we have to do to stop drugs,” Trump said Monday, adding that he’s “not happy with Mexico.”

The U.S. Embassy in Mexico shared a video on X later Monday that included previous comments from Rubio saying that the U.S. would not take unilateral action in Mexico.

Meanwhile, Mexican and U.S. diplomats were trying to sort out Tuesday what may have been an actual U.S. incursion.

On Monday, men arrived in a boat at a beach in northeast Mexico and installed some signs signaling land that the U.S. Department of Defense considered restricted.

Mexico’s Foreign Affairs Ministry said late Monday that the country’s navy had removed the signs, which appeared to be on Mexican territory. And on Tuesday, Sheinbaum said that the International Boundary and Water Commission, a binational agency that determines the border between the two countries, was getting involved.

The signs, driven into the sand near where the Rio Grande empties into the Gulf of Mexico, caused a stir when witnesses said men in a boat arrived at the local beach known as Playa Bagdad and erected them.

The signs read in English and Spanish, “Warning: Restricted Area” and went on to explain that it was Department of Defense property and had been declared restricted by “the commander.” It said there could be no unauthorized access, photography or drawings of the area.

The U.S. Embassy in Mexico shared a comment from the Pentagon Tuesday about the incident, confirming that contractors putting up signs to mark the “National Defense Area III” had placed signs at the mouth of the Rio Grande.

“Changes in water depth and topography altered the perception of the international boundary’s location,” the statement said. ”Government of Mexico personnel removed 6 signs based on their perception of the international boundary’s location.”

The Pentagon said the contractors would “coordinate with appropriate agencies to avoid confusion in the future.”

Mexico had contacted its consulate in Brownsville, Texas and then the U.S. Embassy in Mexico City. Eventually, it was determined that contractors working for some U.S. government entity had placed the signs, Sheinbaum said.

“But the river changes its course, it breaks loose and according to the treaty you have to clearly demarcate the national border,” Sheinbaum said during her daily press briefing.

The area is close to SpaceX Starbase, which sits adjacent to Boca Chica Beach on the Texas side of the Rio Grande.

The facility and launch site for the SpaceX rocket program is under contract with the Department of Defense and NASA, which hopes to send astronauts back to the moon and someday to Mars.

In June, Sheinbaum said the government was looking into contamination from the SpaceX facility after pieces of metal, plastic and rocket pieces were reportedly found on the Mexican side of the border following the explosion of a rocket during a test.

The area also carries the added sensitivity of Trump’s order to rename the Gulf of Mexico as the Gulf of America, which Mexico has also rejected.
