Argentine President Javier Milei has escalated the long-standing Falklands sovereignty dispute by threatening tough sanctions against British and Israeli firms developing the Sea Lion oil field. Milei's aggressive stance follows comments from U.S. President Donald Trump, who suggested Washington might abandon its neutral stance on the islands due to a lack of British military support against Iran. While Milei frames this as a diplomatic victory, UK officials have dismissed his threats as domestic posturing to distract from his falling 34% approval ratings, reiterating that British commitment to the islands remains absolute.
