Argentina's Milei sanctions oil firms in Malvinas, plans naval base, rejects islander self-determination

Argentine President Milei announced sanctions against oil companies operating in the Malvinas/Falklands, creation of a naval base, and a national security council, explicitly rejecting the islanders' right to self-determination. This escalates Argentina's sovereignty claim over the islands and directly challenges UK oil extraction in the region. The move signals a more assertive posture, though concrete implementation and UK response remain uncertain.
