US President Donald Trump on 16 October 2026 declared that drug cartels effectively control Mexico, warning that his administration was preparing to intensify operations against trafficking networks on land — even as he acknowledged that Mexican President Claudia Sheinbaum was unhappy with his characterisation.

Trump made the remarks at a White House Rose Garden luncheon honouring first responders, where he also claimed the administration had driven a 97% reduction in maritime drug trafficking and a 67% drop in fentanyl flows across the southern border, though he did not cite the base period or data source for either figure.

Trump's Remarks on Mexico and the Cartels

'We're working with Mexico. But unfortunately, the cartels run Mexico. I tell that to the president of Mexico. She's not happy. She's a great woman, wonderful woman, but the cartels run Mexico,' Trump said, addressing the gathering.

The President argued that Mexico was unwilling — and, in his view, incapable — of dismantling the cartels itself. 'Mexico should be doing it, but honestly, they're not capable of doing it,' he said, adding that cartel members had reportedly been given a window to surrender, though he offered no details on the mechanics or timeline of any such warning.

Maritime Operations and Missile Strikes

Trump described a phased enforcement strategy in which his administration initially focused on sea routes because, as he put it, maritime trafficking presented the harder enforcement challenge. He confirmed the use of missiles against suspected drug-trafficking vessels, saying the strikes had sharply reduced traffickers' willingness to attempt maritime crossings.

'Those missiles come and they hit those boats dead center, and you feel terribly for the people,' Trump said, defending the operations by arguing that the drugs aboard such vessels caused widespread deaths among American families.

He also drew laughter from the gathering by joking that the operations had inadvertently discouraged recreational boating and fishing, as people feared being misidentified as traffickers.

Border Security Claims

Trump credited Immigration and Customs Enforcement (ICE) and Border Patrol personnel with what he described as a historically secure southern border, claiming illegal crossings had fallen dramatically under his administration.

National Border Patrol Council President Paul Perez, who also addressed the gathering, said the administration had provided unprecedented support to first responders and border enforcement personnel, crediting Trump's leadership with improving national security outcomes.

Context and What Comes Next

The remarks sit within a sustained effort by the Trump administration to keep border security, illegal immigration, and narcotics trafficking at the forefront of its domestic agenda. The United States and Mexico share an extensive land border and deep economic ties; counter-narcotics cooperation between the two governments has historically relied on intelligence sharing, law enforcement coordination, and joint operations against cross-border criminal organisations.

Trump's assertion that cartels 'run Mexico' is a more sweeping claim than official US government assessments have typically made and is likely to strain diplomatic relations further. Notably, the Mexican government has previously pushed back sharply against any suggestion of reduced sovereignty, and Sheinbaum has resisted US pressure to allow American law enforcement operations inside Mexican territory.

With Trump now signalling a shift toward harder land-based enforcement, the next weeks are likely to test how far that cooperation — or confrontation — extends.
