U.S. readies mission in Mexico against cartels
Detailed planning for troops in Mexico without consent
On November 3, 2025, NBC News reported that two current and two former U.S. officials said the Trump administration had begun detailed planning and initial training for a covert operation to send American troops and intelligence officers into Mexico to target drug cartels, though no deployment was imminent (nbcwashington.com). At her morning press conference in Mexico City that same day, President Claudia Sheinbaum declared unilateral U.S. military action on Mexican soil “won’t happen” and confirmed Mexico has not consented to any U.S. forces operating within its borders (reuters.com).
Why this matters
Sending U.S. forces into Mexico without consent would violate the international prohibition on the use of force under the United Nations Charter Article 2(4) and infringe Mexico’s sovereignty (reuters.com). The War Powers Resolution (1973) requires the president to obtain congressional authorization for military actions beyond 60 days, so a covert deployment risks exceeding executive authority (reuters.com). Voters concerned about unchecked military operations should urge their representatives to enforce these legal limits and demand transparency on any cross-border missions.
Core Facts
U.S. reporting describes preliminary planning by administration officials for an operation that could include U.S. troops and intelligence officers in Mexico to target cartels; reporting characterizes the work as early-stage planning and training, not an executed mission.
Mexican President Claudia Sheinbaum said she rejected any offer to allow U.S. troops on Mexican soil and emphasized Mexico’s sovereignty.
A unilateral U.S. military operation on Mexican territory would be historically unusual; the last major U.S. ground incursion into Mexico dates to the 1916–17 punitive expedition.
