Argentine President Javier Milei told the U.N. General Assembly that Argentina would “take matters into our own hands” over Falklands/Malvinas sovereignty and criticized U.K. oil exploration near the islands, according to The Guardian (opens in new tab), MercoPress (opens in new tab), and the Buenos Aires Herald (opens in new tab).
Milei attacked the United Nations as ineffective and argued self-determination should not apply because the population was “implanted” by the occupying power, the cited outlets reported. No military action was announced in the speech packages.
The U.K. U.N. mission filed a written reply stating it has “no doubt” about sovereignty and supporting islanders’ self-determination, citing the 2013 referendum in which 99.8% voted to remain British on 92% turnout, MercoPress (opens in new tab) and the Herald said. London called Argentine measures against oil and service companies an unacceptable attempt at extraterritorial jurisdiction.
U.K. Prime Minister Andy Burnham separately told Trump that Britain would stand firm on islanders’ right to remain British, per the same regional and Guardian accounts. The Event Log dual-attributes the sovereignty dispute and treats Milei’s phrasing as diplomatic rhetoric, not an announced use of force.
