Argentine President Javier Milei delivered a televised address on September 4, 2026, declaring that global shifts, including US President Donald Trump's recent remarks, favor Argentina's sovereignty claim over the Falkland Islands. He announced decrees to sanction oil companies operating in the disputed waters and to boost military presence in Tierra del Fuego, while the UK reaffirmed its long-standing position.

A Diplomatic Gambit Amid Global Shifts

In a nationally televised speech on September 4, 2026, Argentine President Javier Milei declared that the 'winds of change' are blowing in favor of Argentina's claim to the Falkland Islands (known in Spanish as Islas Malvinas). Milei cited recent comments by former US President Donald Trump, who in an interview with GB News on September 3 suggested that the United States might not support the United Kingdom in the sovereignty dispute, referencing the UK's lack of assistance in the US conflict with Iran.

Milei interpreted Trump's remarks as a 'threat' that should not be taken lightly, noting that the US has historically recognized British administration of the islands without taking a formal stance on sovereignty. This perception is bolstered by reports from April 2026, when an internal Pentagon email, revealed by Reuters, mentioned the possibility of punishing NATO allies who did not join the war against Iran.

New Measures: Sanctions and Military Reinforcement

In the same address, Milei announced two key decrees. The first aims to accelerate sanctions against companies involved in oil extraction in the North Falkland Basin, an offshore project led by Israeli firm Navitas and British firm Rockhopper. According to the Argentine government, these operations violate UN calls against unilateral action in the area.

The second decree declares an emergency to increase resources for the Ministry of Defense, prioritizing the construction of an integrated naval base in Tierra del Fuego, whose works began in 2022. This measure aims to strengthen Argentina's presence in the South Atlantic.

UK Response: 'Unwavering' Position

The British government responded swiftly, reaffirming its 'long-standing and unwavering' position on British sovereignty over the islands and the right to self-determination of the islanders. In the 2013 referendum, 99.8% of residents voted to remain a British Overseas Territory, a fact London uses as a central argument.

Domestic Context: Milei at a Delicate Moment

The announcement comes at a time of low popularity for Milei, with corruption accusations in his government, rising unemployment and poverty, and controversial measures such as anti-Argentina claims from the World Cup, attacks on Brazilian President Lula, and an ICE-style immigration crackdown. Historically an admirer of Margaret Thatcher, Milei adopted a pro-sovereignty stance only a few months ago, following reports of a potential US policy shift.

In his speech, Milei used the phrase 'Las Malvinas son argentinas' (The Malvinas are Argentine), the same slogan displayed by the Argentine national team on a banner against England during the World Cup, seeking to connect with popular sentiment.
