Speaking to the UN on Wednesday, Milei said the United Nations had “looked the other way” on the disputed South Atlantic archipelago and announced that Buenos Aires would take matters into its own hands through what he described as a “peaceful, practical and effective defence”.
He dismissed the wishes of the island’s residents – who have repeatedly voted to remain a British Overseas Territory – arguing that the principle of self‑determination does not apply because the population was “implanted by the occupying power on a territory whose sovereignty is in dispute”.
The British delegation responded that the United Kingdom has “no doubt about its sovereignty over the Falkland Islands” and reaffirmed its support for the Falklanders’ right to self‑determination, calling Argentina’s attempts to obstruct international companies operating in the islands “wholly unacceptable” and not the behaviour expected of a democracy.
British diplomats at the UN added that Argentine law “does not apply to the Falkland Islands” and warned that the ongoing harassment of firms involved in hydrocarbon exploration constitutes an illegal exercise of extra‑territorial jurisdiction, contrary to international law and free‑trade principles.
Milei’s statements come after Argentina imposed sanctions earlier this month on individuals and firms linked to oil exploration around the islands and announced a criminal complaint against Navitas Petroleum, as well as a sweeping security bill that expands the military’s role in protecting critical infrastructure.
The renewed diplomatic clash revives memories of the 1982 Falklands War, which claimed 255 British and 655 Argentine lives, and occurs amid speculation that U.S. President Donald Trump may reconsider Washington’s traditionally neutral stance after recent remarks questioning the UK’s ability to defend the territory.
Deputy Prime Minister Andy Burnham reiterated that the United Kingdom will “stand firm in the face of any threats” to the islands, while Milei called on the UK to resume negotiations to find a peaceful solution in line with international law.
