Argentina escalates Falklands dispute after Trump questions UK support

On September 4, 2026, Argentine President Javier Milei escalated the Falkland Islands dispute, threatening military bases and sanctions against the UK, and declaring the islands Argentine territory. This followed comments by President Donald Trump suggesting he would not help the UK in another Falklands conflict. The UK government reaffirmed its 'unwavering' and 'unshakeable' commitment to the Falkland Islands, responding to Milei's remarks. The escalation appears to be fueled by Trump's statements, which Milei has seized upon to press Argentina's claims.
