Why is Donald Trump threatening the Falklands?

The Trump administration’s threat to review its position on Britain’s claim to the Falkland Islands could have a significant impact on the future of the South Atlantic British Overseas Territory, analysts have said.

A leaked internal Pentagon memo published last week by Reuters revealed that, as punishment for not supporting Donald Trump’s war against Iran, the US could reassess diplomatic support for longstanding European “imperial possessions”, such as the ⁠Falkland Islands, which have been administered by Britain since 1833 but are still claimed by Argentina.

Argentina’s President Javier Milei is “upbeat about the prospects”, said Reuters, after the Trump ally told a radio show that “we are doing everything humanly possible to bring the Falkland Islands back into Argentine hands”.

On Monday, his vice president, Victoria Villarruel, ramped up rhetoric further by calling for Falkland Islanders to go back to England.

What did the commentators say?

Donald Trump “has repeatedly demonstrated his desire to use transactional diplomacy to pressure both allies and adversaries”, said the BBC. The Falklands are a “pressure point for the UK but irrelevant to the US”, making them a perfect target for this kind of “leverage”.

Given the current state of Britain’s armed forces, the UK would “struggle to defend the Falkland Islands if Donald Trump followed through on threats to withdraw American support for British sovereignty”, said The i Paper.

But while the loss of American backing for UK control of the islands would “make it easier for Argentina to press its claim more assertively”, said Dr Johanna Amaya-Panche, senior lecturer in international relations and politics at Liverpool John Moores University, an invasion remains unlikely.

“Argentina is not capable of retaking the islands militarily, and there is no credible indication that it intends to try,” but the Milei government “may adopt a more assertive diplomatic or legal strategy, seeking to internationalise the dispute and mobilise external support”.

Downing Street has insisted that the Falkland Islands’ status will remain unchanged, with the prime minister’s spokesperson saying “sovereignty rests with the UK and the islanders’ right to self-determination is paramount”.

“Such robustness is a welcome surprise,” said The Telegraph in an editorial. The government will be hoping the state visit by King Charles will help defuse tensions with the White House. The reality is that “casting doubt over the ownership of the Falklands would hardly be in Washington’s interests”. Even in 1982, the Royal Navy “had to leave other missions unresourced in order to retake the islands” and today its numbers are “so shrunken that it could never act meaningfully in the South Atlantic and in support of the US simultaneously”.

What next?

If the US did change its position to one in which it supported Argentinian claims over the islands, that would be “pretty significant”, Ed Arnold from the Royal United Services Institute security think tank, told the BBC, as “it might cause other countries to move that way as well”.

“You could potentially see a situation where Argentina pushes for some intervention at the UN and the US may support or just not actively block.”

“A change of US policy towards the sovereignty of the Falklands will not mean we will face a repeat” of the 1982 war with Argentina, said former defence secretary Penny Mordaunt in The Express. “But it should be a reminder that the world can change fast” and that “we owe it to all Brits, whether they reside in the UK or in her territories, that we are capable of defending them and their interests.”
