Milei gives Britain two weeks over Falklands oil

Argentina has given the British government a deadline and, in the process, revived a dispute that has outlived more than one generation of politicians. President Javier Milei said oil exploration at the Sea Lion project off the Falkland Islands must stop within two weeks, or Argentina will move ahead with legal action against the UK.

The project is a joint venture between Britain’s Rockhopper Exploration and Israel’s Navitas Petroleum. It lies about 130 miles, or 209 kilometres, from the Falkland Islands and is estimated to contain 1.7 billion barrels of oil. The companies say they hold valid licences issued by Britain, which leaves the legal argument exactly where these disputes usually end up: in the gap between sovereignty claims and paperwork.

Milei said he had instructed the Foreign Ministry and legal teams to begin international arbitration if what he called the illegal plundering of resources through the Sea Lion Project was not stopped. He also warned that if the alleged illegitimate exploitation continued, Argentina would take the case to the International Tribunal for the Law of the Sea in Hamburg, the independent court responsible for applying the UN Convention on the Law of the Sea.

The move comes after Milei used his speech at the UN General Assembly to attack the organisation for failing to act on the sovereignty dispute over the islands. He called the UN a useless organisation and said it served arrogant parasites dressed up as well-intentioned bureaucrats. The UK Defence Secretary, Wes Streeting, said Argentina lacks the ability to take back the Falklands by force.

The wider background is familiar, if no less stubborn for that. Argentina refers to the islands as Las Malvinas, and the sovereignty dispute dates back to 1982, when Argentine forces landed there and a British military task force expelled them after 74 days of war. The conflict left 255 British military personnel, three islanders and 649 Argentine military personnel dead.

There is also the islanders’ own position, which tends to be treated as a footnote by governments with larger ambitions. In a 2013 referendum, residents voted overwhelmingly to remain a British overseas territory, with 99.8% in favour and only three votes against. That result has not settled the argument, but it has made clear where the people living there stand. For now, Milei has turned the issue into a legal deadline; whether that leads to arbitration or simply another round of paperwork and posturing depends on how seriously both sides want to test the machinery of international law.
