Streeting's warning to Argentina
UK Defense Secretary Wes Streeting said London is ready to defend the Falkland Islands militarily if Argentina takes action against the archipelago. In an interview with The Sun on Sunday, he said Britain's armed forces have what they need to protect the islands. Asked whether the UK would respond militarily if Argentina sent warships toward the Falklands, he answered yes. He also said he does not expect a conflict but stressed Britain's defensive capability.[S1][S2][S5]
Streeting rejected President Javier Milei's repeated sovereignty claims, calling them unfounded, and said Argentina does not have the capacity to take the islands by force. He described the Argentine government's position as a complaint repeated year after year. In one remark he used a derogatory term for Argentines, which is reported here only because of its news relevance. He also said the dispute was settled after the 1982 Falklands War, when Britain regained control of the archipelago following a 74-day conflict.[S1][S2][S3][S6]
The defense secretary pointed to the islanders' expressed will to remain linked to London. In the 2013 referendum, 99.8% of voters in the Falklands backed continuing under British administration, according to figures cited by The Sun on Sunday. Argentina maintains its sovereignty claim over the islands it calls Malvinas, as well as South Georgia, the South Sandwich Islands and surrounding maritime spaces. Britain administers the archipelago and says the matter is resolved, while Argentina considers it an unresolved sovereignty dispute that should be settled through bilateral negotiations.[S1][S2]
Oil project and military buildup raise tension
Streeting's comments came after a political escalation between Argentina and the UK during September. The controversy intensified after remarks by US President Donald Trump about a possible review of Washington's position on the archipelago. On September 3, Milei announced sanctions on companies extracting hydrocarbons in the area without Argentine authorization, funds for a naval base in Tierra del Fuego and a bill on the Defense of National Sovereignty. The measures targeted, among others, the Sea Lion oil project, located 220 kilometers north of the islands and planning to start production in 2028.[S1][S2]
British authorities estimate the development could generate 2 billion dollars in royalties over 30 years. The project is driven by a consortium made up of Rockhopper Exploration, with British capital, and Israel-based Navitas Petroleum. Britain's response included rejecting the Argentine sanctions and confirming that the four Typhoon Tranche 1 fighters deployed in the archipelago will be replaced by more capable Tranche 2 aircraft at the end of November 2027. The UK Ministry of Defence said the change is a rotation planned before the current diplomatic tension.[S1][S2]
In the courts, federal judge Mariel Borruto in Río Grande ordered as a precautionary measure that the named oil companies refrain from starting or continuing the works needed to launch the project. At the same time, Argentina's Foreign Ministry was preparing steps before the United States for Washington to consider mediation, a possibility that would require London's acceptance.[S1]
Milei's UN speech and Russia threat
Streeting's remarks followed Milei's speech this week before the UN General Assembly, where he again raised Argentina's claim to the Falklands. Milei said the Malvinas are a national cause for Argentina and argued the dispute is not exclusively bilateral, calling for the body's resolutions to be taken into account. He said Argentina chooses a peaceful and effective defense and questioned Britain's argument based on the islanders' self-determination. British representatives at the UN responded by reaffirming London's historical position and said hydrocarbon development in the Falklands is legitimate.[S3][S4][S6]
In his interview with The Sun, Streeting also called for a sustained increase in defense spending, citing the risk of a conflict with Russia. He identified Russian President Vladimir Putin as the main threat to the UK and said there is a greater risk of war than at any other time in his life. He argued that military power is indispensable to defend against potential external aggression and warned that budget inaction could compromise British national security within five years.[S3][S4][S5]
