In April 1982, Britain dispatched a force of more than 120 ships to retake the Falkland Islands: two carriers, more than a dozen destroyers and frigates, plus auxiliaries and requisitioned merchantmen. It did so without suspending its other commitments around the world. The operation took seventy-four days, cost 255 British and 649 Argentine lives, and proved to the planet that the United Kingdom could still project military power across the Atlantic.
Today, in 2026, the Royal Navy has sixty-three commissioned ships. Only twenty-five qualify as warships: ten submarines, two carriers, six destroyers and seven frigates. For perspective: in 1996, fourteen years after the Falklands, the fleet still held seventeen submarines, three carriers, fifteen destroyers and twenty-two frigates. In thirty years the combat fleet was cut in half. Britain's global commitments were not.
If London had to repeat the 1982 operation tomorrow, emptying every harbour and abandoning every other commitment, the Royal Navy could muster one carrier, two destroyers and five frigates. Four additional frigates sit at Fareham Creek waiting to be towed to a Turkish breaker's yard, with no immediate replacement. River-class patrol vessels, under two thousand tonnes, armed with a single gun, now cover commitments in the Falklands, the South Pacific and home waters that used to belong to frigates and destroyers. Patrol boats doing warship work because the warships are not available.
The crisis stopped being theoretical in March of this year. When Iran struck the British base at RAF Akrotiri in Cyprus with drones, the Royal Navy could not get a destroyer there in time. HMS Dragon took several days to reach the region. France, meanwhile, deployed its nuclear carrier Charles de Gaulle. Neither British carrier took part in the operations against Iran; both were dragging chronic mechanical problems. A retired Royal Navy submariner told The Times that buying two giant carriers, instead of concentrating on the smaller ships that sustain a country's naval capability, had been a mistake.
These numbers are not in dispute, and they are worth bearing in mind whenever anyone thinks about the Falklands.
Diplomacy without teeth
The last two decades of Argentine policy on the Falklands contain a paradox worth stating bluntly: the governments that talked the loudest about sovereignty were the ones that did the most to destroy any capacity to back the claim.
When the military junta invaded the islands in 1982, Argentina had an air force of more than four hundred aircraft, including modern fighters. It had a navy with a carrier, a cruiser, recent submarines, destroyers and frigates. It lost the war, but not for lack of equipment. It lost because of poor operational planning, improvised logistics and, above all, an underestimation of British resolve. The defeat, combined with the crimes of the dictatorship, destroyed the public standing of the Argentine armed forces. What came after was worse than the defeat itself.
Defence spending fell from 4.4% of GDP in 1983 to less than 1% during the Kirchner years, where it stayed for more than a decade. But the numbers don't tell the whole story. What the Kirchner administrations did was deeper than budget cuts: they turned the armed forces into an internal enemy. Néstor Kirchner took office in 2003, and one of his first symbolic acts was to remove the portraits of the military dictators from the walls of the Military College. He reopened the Dirty War trials, purged the senior leadership of all three services, and limited the role of the armed forces by decree to "external aggression", defined as narrowly as possible. Cristina Kirchner finished the job: another mass purge in 2012, budget cuts that left aircraft without spare parts, ships without maintenance, soldiers without basic kit.
The figure that captures it best came from Macri's own Defence Minister: in the Falklands War, Argentina lost seventy-two aircraft. Under Kirchnerism, it lost more than a hundred. Not in combat, but to neglect. The Córdoba aircraft factory employed fifteen hundred people and went ten years without building a single plane. When the Mirage III was retired in 2015, Argentina lost its supersonic intercept capability. Not for a year or two: for a full decade. The largest Spanish-speaking country in the world, the eighth largest territory on the planet, with a constitutional claim of sovereignty over disputed territory, could not intercept an aircraft that violated its own airspace.
The sinking of the submarine ARA San Juan in November 2017, with forty-four crew on board, was the most tragic symbol of that decay. It was not an isolated accident. It was the logical consequence of decades of budgetary abandonment.
Kirchnerism claimed the Falklands with its mouth while disarming the country with both hands. Twenty years of speeches at the United Nations, plaques on street corners and patriotic holidays did not change a single fact on the ground. Nobody negotiates seriously with someone who has nothing to back up his words.
The Strait and Antarctica
There is a geographical dimension that tends to drop out of any discussion of the Falklands and that matters more every year: the position of the southern tip of South America on the global board.
The Strait of Magellan is the main natural waterway between the Atlantic and the Pacific. It belongs mostly to Chile, but its eastern mouth is shared with Argentina, and Ushuaia and Río Grande are the southernmost cities of the continental world. The Drake Passage, south of Cape Horn, is the narrowest point of the circumpolar Antarctic ocean. Whoever holds a meaningful presence in this region controls access to Antarctica, a continent whose natural resources are frozen, in the literal and the legal sense, by a treaty whose environmental protection regime can be reopened from 2048.
That date matters. When the Antarctic Treaty rules are renegotiated, the position of each country in the region will determine the strength of its claims. Argentina, Chile, Britain, Norway and others all hold overlapping territorial claims in Antarctica. Physical presence, scientific bases, logistical capacity and naval projection will count for more than any legal document. The Falklands, South Georgia and the South Sandwich Islands, all under British administration and all claimed by Argentina, are logistical platforms for projecting that presence. They are not an archipelago of three thousand two hundred residents and a million penguins. They are geopolitical infrastructure.
Britain understands this perfectly. The Mount Pleasant base, opened in 1985, does not exist to defend the islanders from an Argentine invasion. It exists to hold a strategic position in one of the few regions of the world that could still be redistributed in the coming decades. The current garrison consists of about twelve hundred personnel, four Typhoon fighters, a tanker, a transport aircraft, a Sky Sabre air defence system and a single patrol vessel, HMS Forth, a two-thousand-tonne ship with minimal armament. It is a deterrent force, not a combat force: it is designed to make any aggression politically costly, not to win a war. Its viability depends entirely on Britain being able to reinforce it quickly from the home islands. Given the state of the Royal Navy, that assumption looks more questionable every year.
In a world where the Strait of Hormuz is closed by the war with Iran and the Suez Canal is still affected by regional instability, alternative maritime routes gain weight. The Strait of Magellan and Cape Horn will not replace Panama, but the idea that the southern tip of the continent is irrelevant to global geopolitics is a luxury no one can afford anymore.
The Trump administration's National Security Strategy defines the hemisphere all the way to Antarctica. That is no accident.
The F-16s and the end of the embargo
On 5 December 2025, the first six F-16 AM/BM Fighting Falcons touched Argentine soil at Río Cuarto Air Base in Córdoba. Milei greeted them in person, and for once the presidential rhetoric matched the facts: this was the most significant military acquisition in half a century. Twenty-four fighters bought from Denmark for about three hundred million dollars, plus an American weapons package of another three hundred and ten million that included AIM-120 and AIM-9 missiles, reconnaissance pods and electronic warfare kits. After a decade without supersonic capability, the Argentine Air Force had modern fighters again.
But the F-16s are the least interesting part of the story. What matters is how they got there.
For forty years, Britain enforced a systematic blockade on the sale of Western armaments to Argentina. London did not just refuse to sell: it pressured its allies not to sell either. It vetoed the sale of replacement Mirages from France. It blocked the possible transfer of Saab Gripens from Brazil because their avionics had British origin. It killed the sale of Israeli Kfirs and complicated the Korean FA-50. The strategy was simple and effective: most Western combat aircraft use Martin-Baker ejection seats or BAE systems, both British. As long as those components were present, London held a veto. Carlos Menem, in the nineties, slipped thirty-six second-hand A-4 Skyhawks past the blockade through a crack in the American door, but it was the exception.
The detail that made the Danish deal possible is technical but decisive: Danish F-16s use the American ACES II ejection seat, made by Collins Aerospace, not the British Martin-Baker. There was nothing London could veto on that front. But the embargo had never been only technical. It had also been political, and that is where Operation Peace Condor matters. Washington pushed the deal forward, negotiated with London, and the United Kingdom eventually agreed. After forty years of automatic deference to British preferences on anything to do with Argentine armaments, the United States decided it was no longer worth paying that price to spare the feelings of an ally it was, at the same time, beginning to treat as an increasingly awkward partner.
The F-16 sale came packaged with something broader. Eight Stryker armoured vehicles, also American. Discussions about air surveillance radars, helicopters, space cooperation, cyberdefence and, notably, maritime operations in the South Atlantic. The Department of Defense described Argentina as a country in transition from "peripheral ally" to "central security partner in the Western Hemisphere". That phrase carries more geopolitical weight than any speech at the UN.
Nobody is suggesting that twenty-four F-16s give Argentina the capability to retake the Falklands by force. That is not the point. The F-16 MLUs that Argentina received are similar to those operated by the Chilean Air Force, which establishes, for the first time in decades, technical parity across the Andes. Against the British Typhoons stationed at Mount Pleasant, the F-16 is a generation behind. Initial operating capability for at least one squadron is expected by 2027, with the rest of the aircraft delivered in phases through 2028. It is a process, not a switch.
The point is bigger than tactical parity. A country with credible armed forces negotiates from a different position than a disarmed one. The signals coming from Washington are no longer what they were five years ago. And London, for the first time in forty years, could not stop its main ally from arming its adversary in the South Atlantic.
This is OUR Hemisphere
On 3 January 2026, American special forces captured Venezuelan President Nicolás Maduro in a night operation in Caracas. Codenamed Resolución Absoluta, it was the most aggressive act of US power projection in the Western Hemisphere since the invasion of Panama in 1989. Hours later, Trump gave a press conference at Mar-a-Lago and delivered a line that should interest any Argentine thinking about the Falklands: "The Monroe Doctrine is a big deal, but we've superseded it by a lot. They now call it the 'Donroe Doctrine.'"
The Monroe Doctrine, formulated in 1823, was a declaration that European powers should not extend their influence into the Western Hemisphere. For two centuries it was an abstraction American presidents invoked when convenient and ignored when not. Trump turned it into operational policy. His National Security Strategy, published in December 2025, includes a "Trump Corollary" stating the intention to "reaffirm and enforce the Monroe Doctrine to restore American preeminence in the Western Hemisphere". The document declares that the United States will "deny non-hemispheric competitors the ability to position strategically vital forces or assets" in the region.
Secretary of State Marco Rubio summarised it with his usual subtlety: "This is OUR Hemisphere". Defence Secretary Pete Hegseth added: "America can project our will anywhere, anytime. Welcome to 2026."
These declarations deserve to be taken seriously, because the facts back them. Trump did not just take Maduro: he revived his campaign to acquire Greenland, threatened tariffs against countries that defended Danish sovereignty, redefined the Gulf of Mexico, and left intervention in Colombia and Cuba on the table. The Atlantic Council, one of the think tanks closest to the US national security establishment, published an analysis recommending that the hemisphere be defined "from the Aleutian Islands to Greenland and the North American Arctic down to Antarctica, with Central America, South America and the Caribbean in between, and the Pacific and Atlantic approaches included".
If that is the operational definition of the hemisphere, the Falkland Islands fall, objectively, inside it. They are territory administered by a European power, six hundred kilometres off the Argentine coast, with a military base hosting twelve hundred personnel, four Typhoon fighters and a patrol vessel. By the logic of the Donroe Doctrine, that is precisely the kind of extra-hemispheric presence Washington says it wants to remove.
There is a historical irony worth flagging. The Monroe Doctrine was formulated in 1823, ten years before Britain expelled the Argentine authorities and population from the Falklands in 1833. The British occupation occurred, strictly speaking, in violation of the spirit of the doctrine that Trump now claims to want to restore. When the British landed at Puerto Soledad and lowered the Argentine flag, the United States was a young country without the strength to enforce Monroe. Two hundred years later, it has more than enough.
None of this is a prediction. Trump has not mentioned the Falklands. There is no indication he will. What there is is something more subtle and, in the medium term, more important: an American strategic framework that, if applied with any consistency, makes the British military presence in the South Atlantic increasingly difficult to justify. Not to Buenos Aires, which always considered it illegitimate, but to Washington, which had tolerated it without question.
Milei seems to have grasped this. In his opening address to Congress on 1 March he spoke of building "the century of the Americas", of Argentina holding the critical minerals the West demands, and of its strategic location with access to two oceans and proximity to Antarctica. "We are a natural link in the strategic value chain of the West," he said. He did not mention the Falklands in that passage. He didn't need to.
This is not Winston Churchill
To understand the window opening for Argentina, one has to understand what is happening to the relationship between the United States and Britain. And what is happening, in diplomatic terms, is a disaster.
The so-called "special relationship" between Washington and London, forged during the Cold War on shared intelligence, nuclear cooperation and cultural affinity, is at its lowest point since Churchill coined the phrase in 1946. The tensions did not start with Iran, but Iran pushed them to breaking point.
When the United States struck Iranian nuclear facilities in February 2026, Prime Minister Keir Starmer refused to allow American forces to use British bases, including RAF Fairford and the facilities at Diego García. He eventually relented in part, but Trump considered it too late. The response was public and brutal: "He ruins relationships. We are very surprised. This is not Winston Churchill that we're dealing with."
That line, delivered at a White House cabinet meeting on 26 March, was more than an insult. It was a declaration that the special relationship is no longer, in the eyes of this president, particularly special. Trump also called the British carriers "old, broken toys", a humiliation the Royal Navy had not received from an ally in its modern history.
Iran is only the most recent chapter. The list of grievances is long and growing. Trump repeatedly criticised the cession of the Chagos Islands to Mauritius, calling them "that stupid island" and accusing the United Kingdom of being "very, very uncooperative". Starmer publicly opposed Trump's Greenland campaign, which triggered the threat of a 25% tariff on British goods. The United Kingdom refused to join Trump's "Board of Peace". In November 2025, London suspended intelligence-sharing with Washington on Caribbean drug vessels, considering the American strikes against those craft to be illegal.
The Chagos case deserves a closer look, because it has a direct parallel with the Falklands that has not received enough attention. The Chagos are an archipelago in the Indian Ocean where the joint US-UK military base of Diego García operates. In 2024, the British government ceded sovereignty over the islands to Mauritius, an act Trump condemned as "great stupidity and total weakness". The cession infuriated Washington because it put the future of a shared strategic base at risk. If Britain has already given away one disputed territory that hosted a joint base with the United States, the question is obvious: how much does it really matter to London to hold on to the Falklands, a territory farther away, more expensive to defend, and of no strategic value to Washington?
Britain not only has fewer ships than in 1982. It has fewer friends in Washington than at any point in the postwar era. For a country that depends on the United States for the credibility of its nuclear deterrent, for the maintenance of its Trident submarines, and for the legitimacy of its global standing, this is no minor inconvenience. It is an existential crisis in slow motion.
An unprecedented relationship
On the other side of the board, Argentina is living the opposite moment.
The relationship between Javier Milei and Donald Trump has no precedent in the bilateral history of Argentina and the United States. It is not just a matter of ideological affinity, although that affinity is real and visible. It is a relationship that has translated into concrete, measurable facts: a twenty-billion-dollar swap line to stabilise the Argentine peso ahead of the 2025 midterm elections, direct purchases of pesos by the US Treasury to support its value, a trade framework signed in November 2025, the facilitation of the F-16 and Stryker deals, and a favourable ruling in the YPF case that saved Argentina sixteen billion dollars.
Milei travelled to the United States fourteen times in his first two years in office. Trump called him his "favourite president". He was the first foreign leader to meet Trump after the 2024 election, and he publicly backed the capture of Maduro when most of the world condemned it. In his March address to Congress, Milei described Trump as a "key ally" and spoke of "building the century of the Americas".
The relationship is asymmetric, as any relationship between a superpower and a developing country must be. Milei needs Trump more than Trump needs Milei. But that asymmetry does not invalidate the central point: Washington's willingness to take Argentine interests into account, even when they collide with British ones, is a new phenomenon. The F-16s prove it. The description of Argentina as a "central security partner" confirms it.
There is one more element worth flagging: Argentina has things Washington wants. It has lithium, copper and rare earths, the critical minerals of the energy transition and the technology industry. It has Vaca Muerta, one of the world's largest unconventional gas reserves, at a moment when the war with Iran has pushed energy prices up. It has access to two oceans, proximity to Antarctica, and a geographical position that, within the framework of the Donroe Doctrine, makes it a natural anchor of the southern hemisphere. The question is whether Buenos Aires has the strategic vision to convert this goodwill into something more durable than photo opportunities and press conferences, and whether it has the discipline to tie, even obliquely, the Falklands question to the agenda of hemispheric cooperation.
The window
These conditions did not exist in 2024. They did not exist in 2020, or in 2010, or at any point since 1982. They might not exist in 2028. The window depends on Trump, whose mandate runs until 2029 but whose attention is famously erratic. It depends on Milei, whose term ends in 2027 and whose domestic position is not secured. It depends on the relationship between Washington and London not recovering, something a change of government in either country could trigger. It depends on the Royal Navy not receiving the budget injection that has been promised to it for decades.
None of this means Argentina should, or could, take the islands tomorrow. That fantasy is as counterproductive today as it was in 1982, when the Junta confused opportunism with strategy. It means something else: that there is serious, quiet, sustained work to be done. Twenty-four F-16s are a beginning, not an end. The most serious deficit is naval, and that is where Argentina has to invest now: submarines, corvettes, maritime surveillance systems, Antarctic capability, a sustained defence budget of 1.5 to 2% of GDP, a state policy that survives this government and the next. Military cooperation with the United States has to become structural, not merely personal: regular joint exercises in the South Atlantic, coordinated Antarctic surveillance, shared naval presence, an infrastructure of cooperation dense enough to survive any change of administration. And Argentina has to play the cards it actually holds. Critical minerals, energy, control of maritime routes, Antarctic logistics. The skill is in playing them so that, when the question of the Falklands inevitably comes up, the American answer is favourable out of self-interest, not sympathy.
Being right is not enough. Argentina has been right about the Falklands since 1833. It was right while Britain was the world's leading naval power, and while it ceased to be. It was right while its own governments disarmed the country, and while the islanders voted what they voted. A right without the power to enforce it is a statement of intent, not a foreign policy. What changed is not who is right. What changed is the balance of power that can turn that right into reality.
Macri tried the path of dialogue and pragmatism, but he had neither the relationship with Washington nor the military capability for that dialogue to amount to more than courtesy. Now, for the first time in forty years, the conditions for a serious claim are starting to align. They will not align on their own. They require resolve, investment, patience, and a strategic seriousness Argentina has rarely shown in its history. To let the opportunity pass would be a historic act of negligence.
The Falklands are not recovered with speeches at the United Nations, or patriotic holidays, or plaques on street corners. They are recovered with aircraft, ships, alliances, and the cold patience to play the long game. In 1982, Britain sent what was needed. Today it could not send half of it. The question is not whether Argentina is right. The question is whether, this time, it will be ready.
