Long before Argentine President Javier Milei delivered his late-night national address announcing new sanctions earlier this week, tensions over the long-running Falkland Islands dispute had already been rising steadily across Argentina. The high-profile celebration of Argentina’s World Cup victory over England this summer, where jubilant players held up a banner declaring “Las Malvinas son Argentinas” in front of euphoric fans, provided a striking visual of this growing friction – yet this simmering resentment stretches back far deeper into modern history.
Opening his televised address from an Argentine perspective, Milei walked through a condensed narrative of the islands’ dispute, doubling down on the core argument that has anchored Argentina’s position for decades: the territory rightfully belongs to Buenos Aires. He framed the 1833 British presence as a colonial invasion that violently seized the land from Argentine control.
The UK government has pushed back on this framing, pointing to key contextual details Milei omits from his retelling. For centuries leading up to the 1830s, multiple European powers had traded control of the unpopulated island chain. When British forces re-established a presence on the islands in 1833, the small Argentine settlement that had been established there had already been removed two years prior – not by British forces, but by the United States. The USS Lexington destroyed an Argentine outpost in December 1831 during a dispute over fishing and sealing rights in the region.
But even as the U.S. played an unacknowledged role in clearing the way for 19th-century British control, Milei is now betting that Washington will become his strongest ally in advancing Argentina’s 21st-century claim to the islands. That confidence comes directly from former (and current candidate for) U.S. President Donald Trump, who recently announced he is re-evaluating the long-standing U.S. position on the Falklands. In a national address to the Argentine people, Milei declared that “winds of change” are blowing for the dispute.
For decades, the U.S. has officially recognized British sovereignty over the Falklands while framing its policy as neutral. That neutrality has always been qualified, however: during the 1982 Falklands War, President Ronald Reagan provided critical material support to British Prime Minister Margaret Thatcher, a move that reinforced the decades-long transatlantic “Special Relationship” between London and Washington.
For Trump, though, that historic alliance has already frayed. He blames current UK Prime Minister Andy Burnham’s predecessor Keir Starmer for the breakdown, after the UK declined to join the U.S. in its war against Iran. In a recent interview with GB News, Trump made his frustration clear: “You weren’t there to help me.” He also dismissed the Falklands as “a long way away” from the U.K. – a point that Falkland Islanders, who voted 99.8% to remain a British overseas territory in a 2013 referendum, have pushed back on: the distance from London to the Falklands is actually slightly shorter than the distance between Washington, D.C. and the U.S. territory of Guam in the western Pacific.
Regardless of that factual pushback, Trump’s comments have already given a major boost to Milei, who is facing growing political pressure at home ahead of next year’s presidential election. His former vice president, Victoria Villarroel, one of his most prominent challengers, has positioned herself as a far harder-line defender of Argentine national sovereignty, repeatedly attacking Milei’s diplomatic approach to the Falklands as weak and ineffective. To counter that attack, leaning into the Falklands dispute and leaning on Trump’s support has become a key political strategy for the incumbent.
Domestic political calculation is far from the only driver of the renewed tension, however. Milei has framed the dispute as newly urgent, warning of what he calls “a clear and urgent danger.” That urgency stems from upcoming energy exploration work: within the next two years, two energy firms – Israeli-owned Navitas Petroleum and UK-based Rockhopper Exploration – plan to begin drilling operations in the Sea Lion oilfield located off the Falklands coast. Milei has rejected this activity outright, arguing Argentina “cannot allow” the companies to “appropriate the oil reserves under our sea” and vowing that Buenos Aires will “not stand by with our arms folded.” FIFA also fined the Argentine Football Association after the World Cup banner incident, which violated global football rules banning political messaging during matches.
Beyond economic and domestic political concerns, the dispute also ties into a broader ideological realignment in the Western Hemisphere. Milei and Trump share deep ideological and personal ties, and Milei has openly framed Argentina as a reliable, “trustworthy partner” for Washington. The two leaders have aligned behind what Trump has dubbed the “Don-roe Doctrine” – a playful reworking of the 19th-century Monroe Doctrine, which established U.S. hegemony across the Americas. The core of this new vision is simple: only ideologically aligned leaders should hold power across the Western Hemisphere.
Within this new framework of reordered spheres of influence, many analysts note it is entirely plausible that Trump will side with his ideological ally Milei over the British Prime Minister, even as the dispute’s implications extend far beyond personal or partisan ties. As the countdown to the U.S. presidential election and Argentine exploration begins, the central question hanging over the coming months is whether this new “Don-roe Doctrine” will outweigh the decades of shared history that define the U.S.-UK Special Relationship.
