In early August 2026, U.S. President Donald Trump amplified a Bill O’Reilly opinion piece that accused Mexico of corruption and called for U.S. troops to operate on Mexican soil against drug cartels. Mexican President‑elect Claudia Sheinbaum responded in Oaxaca, rejecting any foreign military presence and asserting Mexico’s right to determine its own security policies while maintaining bilateral cooperation.

Sheinbaum reiterated her stance the following day, describing Mexico as “a friend of the whole world” and emphasizing that defending sovereignty is a matter of national courage. She noted that about 75 % of firearms seized or voluntarily surrendered in Mexico originate from the United States, underscoring the cross‑border arms‑trafficking issue. She dismissed Trump’s call for U.S. intervention and defended her administration’s security strategy.

The exchange highlights ongoing tensions over cross‑border crime, arms trafficking, and the limits of bilateral security cooperation between Mexico and the United States.
