Argentina threatens legal action over Falklands oil as UK rejects demands

Argentina has threatened legal action against the UK unless it stops work on an oil project off the Falkland Islands within two weeks. Britain rejected the demands, saying the islanders have the right to decide their own future.

The dispute widened into a defence and sovereignty argument. Argentina's president has been threatening companies involved in oil exploration inside British territorial waters around the Falklands, and has talked about legal action. UK minister Wes Streeting said this is not 1982, that Argentina lacks the ability to take the Falkland Islands, and that the UK has the ability to defend them.

That assessment was tested against the military balance. A comparison with 1982 noted a 48% reduction in Royal Navy and Royal Marines personnel, destroyers down from 11 to six, frigates down 87%, and submarine numbers down 68%, though the UK still has two carriers. Major General Chip Chapman, who was in the Falklands in 1982 as an officer in 2 Para, said he believed Wes Streeting was right. He pointed to a quick reaction alert aircraft, Typhoon jets with air-to-air refuelling, A400s, Sky Sabre ground-based air defence and radars, an infantry component from 2 Para, and a South Atlantic patrol ship that would act as a naval tripwire.

Chapman said Argentina has no forward operating base and no amphibious capability. He noted Argentina's defence budget is 0.7% to 0.8% of GDP, with a much lower GDP than the UK and an aspiration to reach 2%, while the UK discusses spending 3% or 5%. He also said indicators and warnings are now at the top of the Joint Intelligence Committee framework, unlike the lowest priority they had in 1982, which would allow significant reinforcements and a capable garrison. In 1982, he said, there were only about 30 marines with little heavy equipment.

He warned against complacency. Chapman said the Falklands can skew British defence and military policy, particularly in areas such as Sky Sabre ground-based air defence, where the UK has a shortage. He also criticised cuts to resource defence expenditure limits, which govern ammunition and training levels, including collective and overseas training, calling such cuts potentially disastrous when budgets are tight.

The discussion also covered wider alliances. It was argued that it would help if the United States were more helpful over the Falklands. Chapman said he believed President Trump would ultimately side with the UK, despite a close friendship with Argentina's Milei and divisions within the Trump administration. He argued it would help if the Labour government dropped the Chagos deal, which he described as an 'awful horrible Chagos surrender deal' that Americans cannot understand, and said the UK needs to increase defence spending significantly. He expected the US to side with the UK in the end.
