In April 1982, Britain sent a fleet to retake the Malvinas that included two aircraft carriers and more than a dozen destroyers and frigates, backed by roughly 120 naval, auxiliary and requisitioned merchant vessels. It did so without scaling back 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 was still capable of projecting military power across the Atlantic.
Today, in 2026, the Royal Navy has sixty-three commissioned vessels. Only twenty-five of them qualify as fighting ships: ten submarines, two aircraft carriers, six destroyers and seven frigates. For perspective: in 1996, fourteen years after the war, the fleet still counted seventeen submarines, three carriers, fifteen destroyers and twenty-two frigates. In thirty years, the combat fleet has been cut in half. Britain's global commitments have not.
If London had to repeat the 1982 operation tomorrow, stripping every port and abandoning every commitment abroad, the Royal Navy could muster one carrier, two destroyers and five frigates. Four additional frigates are moored at Fareham Creek awaiting tow to the breaker's yard in Turkey, with no immediate replacement. River-class patrol vessels of under two thousand tonnes, armed with a single gun, are now covering commitments in the Malvinas, the South Pacific and British home waters that once belonged to frigates and destroyers. Patrol boats doing the work of warships because the warships are not available.
The crisis stopped being theoretical in March of this year. When Iran struck RAF Akrotiri, the British base in Cyprus, with drones, the Royal Navy could not deploy a destroyer in time. HMS Dragon took several days to reach the region. Meanwhile, France dispatched the nuclear-powered Charles de Gaulle. Neither of Britain's two carriers took part in operations against Iran; both were dealing with mechanical problems. The British press described the episode as weak and embarrassing. A retired Royal Navy submariner told The Times that it had been a mistake to buy two oversized carriers instead of the smaller ships that actually sustain a country's naval capability.
None of these numbers are in dispute, and they are worth keeping in mind whenever the Malvinas come up.
Diplomacy Without Teeth
There is a paradox that defines the last two decades of Argentine policy towards the Malvinas, and it deserves to be said plainly: the governments that spoke most about sovereignty were the same ones that destroyed the country's ability to back that claim up.
When the military junta invaded the islands in 1982, Argentina had an air force with more than four hundred aircraft, including modern fighters. It had a navy with an aircraft carrier, a cruiser, new submarines, and state-of-the-art destroyers and frigates. Argentina lost the war, but not for want of equipment. It lost because of poor operational planning, improvised logistics and, above all, because it underestimated Britain's willingness to fight. The defeat, combined with the crimes of the dictatorship, destroyed the public standing of the Argentine armed forces. What came next was worse than the defeat itself.
Defence spending fell from 4.4% of GDP in 1983 to under 1% during the Kirchner years, and stayed there for more than a decade. For context: Colombia, a country without territorial disputes of this magnitude, was spending proportionally more than three times as much. But the numbers alone don't tell the whole story. What Kirchnerism did was something deeper than cutting budgets. It turned the armed forces into a domestic enemy.
Néstor Kirchner took office in 2003, and one of his first symbolic gestures toward the military was to remove the portraits of the dictators from the walls of the Colegio Militar. He reopened the Dirty War trials, purged the leadership of all three services, and restricted by decree the role of the armed forces to "foreign aggression", defined in the narrowest possible terms. Cristina Kirchner completed the job: another mass purge in 2012, and budget cuts that left aircraft without spare parts, ships without maintenance, and soldiers without basic kit.
The single statistic that captures the whole thing came from Macri's own Defence Minister: in the 1982 war, Argentina lost seventy-two aircraft. Under Kirchnerism, more than a hundred were lost. Not in combat, but to neglect. The aircraft factory in Córdoba had fifteen hundred employees and for ten years did not build a single plane. When the Mirage IIIs were 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, with the eighth-largest landmass, with a constitutional claim to disputed territory, could not intercept an aircraft that violated its 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 collapse. It was not an isolated accident. It was the logical consequence of decades of budgetary abandonment.
To be fair, the problem did not begin with the Kirchners. Argentina's disarmament has older roots. After the 1982 defeat, Britain imposed an arms embargo that shut Argentina out of almost all Western military equipment. London didn't just stop selling; it actively pressured its allies to block any transfer. That meant that even governments which wanted to modernise the armed forces, such as Carlos Menem's in the 1990s, found their options limited. Menem managed to buy thirty-six used A-4 Skyhawks from the United States and sent two ships to the Gulf War, which earned Argentina the designation of major non-NATO ally in 1997. These were exceptions in a broader landscape of restriction.
What Kirchnerism did was turn an external limitation into a domestic policy. They did not merely fail to buy weapons; they decided they didn't want any. And twenty years of speeches at the United Nations, of plaques on street corners, of patriotic holidays, changed not a single fact on the ground. No one negotiates seriously with someone who has nothing to back their words up.
The F-16s and the Signal No One Wants to Read
On 5 December 2025, the first six F-16 AM/BM Fighting Falcons touched down on Argentine soil at the Río Cuarto air base in Córdoba. Milei greeted them personally 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 additional three hundred and ten million in American weapons, including 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 this story. The interesting part is how they got here.
For forty years, from the end of the war in 1982, Britain maintained a systematic blockade on the sale of Western military equipment to Argentina. London did not simply refuse to sell; it actively pressured its allies to refuse as well. It vetoed the sale of replacement Mirages from France. It blocked a possible transfer of Saab Gripens from Brazil because they contained British avionics. It prevented the sale of Israeli Kfirs and complicated that of Korean FA-50s. The strategy was simple and effective: many Western combat aircraft use Martin-Baker ejection seats or BAE systems, both British. As long as those components were present, London had a veto.
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 for London to veto through that channel. But the embargo was never purely technical; it was also political, and that is where the Peace Condor operation matters. Washington pushed the deal through, negotiated with London, and the United Kingdom eventually accepted. After forty years of automatic deference to the British position on anything involving Argentine armament, the United States decided it was no longer interested in paying that price to protect the sensibilities 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. Talks on air surveillance radar, helicopters, space cooperation, cyber defence, and, notably, maritime operations in the South Atlantic. The Department of Defense described Argentina as a country in transition from "peripheral ally" to "core security partner in the Western Hemisphere". That sentence carries more geopolitical weight than any UN speech.
Nobody is saying that twenty-four F-16s give Argentina the capability to retake the Malvinas by force. That is not the point. The F-16 MLUs Argentina received are similar to those operated by the Chilean Air Force, which establishes, for the first time in decades, a rough technical parity across the Andes. But against the British Typhoons stationed at Mount Pleasant, the F-16s are a generation behind. The Argentine Air Force is expected to reach initial operational capability for at least one squadron in 2027, with the remaining aircraft arriving in phases until 2028. It is a process, not a switch.
What matters is something bigger than tactical parity. A country with credible armed forces negotiates from a different place than a disarmed one. The signals Washington is sending are no longer the ones it sent five years ago. And London, for the first time in forty years, could not stop its principal ally from arming its adversary in the South Atlantic.
This is OUR Hemisphere
On 3 January 2026, American military forces captured the President of Venezuela, Nicolás Maduro, in a nighttime operation in Caracas. The operation, codenamed Absolute Resolve, was the most aggressive act of American 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 said something that should interest any Argentine who thinks about the Malvinas: "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 the declaration that European powers should not extend their influence into the Western Hemisphere. For two centuries it was an abstraction that American presidents invoked when it suited them and ignored when it didn't. Trump turned it into operative policy. His National Security Strategy, published in December 2025, includes a "Trump Corollary" that sets out the intention to "reaffirm and enforce the Monroe Doctrine to restore American preeminence in the Western Hemisphere". The document states 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 summed it up with his usual subtlety: "This is OUR Hemisphere". Defence Secretary Pete Hegseth added: "America can project our will anywhere, anytime. Welcome to 2026".
These statements are worth taking seriously, because the facts back them up. Trump did not just capture Maduro. He revived his campaign to acquire Greenland, threatened tariffs against countries that defended Danish sovereignty, renamed the Gulf of Mexico, and left open the possibility of intervention in Colombia and Cuba. The Atlantic Council, one of the think tanks closest to the American national security establishment, published an analysis recommending that the hemisphere be defined "from the Aleutians 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 operative definition of the hemisphere, the Malvinas are, objectively, inside it. They are territory administered by a European power, six hundred kilometres off the Argentine coast, hosting a military base with some twelve hundred personnel, four Typhoon fighters and a patrol vessel. They are, in the logic of the Donroe Doctrine, exactly the kind of extra-hemispheric presence Washington says it wants to eliminate.
There is a historical irony worth noting. The Monroe Doctrine was formulated in 1823, ten years before Britain expelled the Argentine authorities and population from the Malvinas in 1833. The British occupation of the islands happened, strictly speaking, in violation of the spirit of the doctrine Trump now says he wants 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 centuries later, it has the strength to spare.
None of this is a prediction. Trump has not mentioned the Malvinas. There is no sign that he will. What there is, is something subtler and, over 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 until now had tolerated it without question.
Milei seems to have understood. In his opening speech to Congress on 1 March, he spoke of creating "the century of the Americas", of Argentina possessing 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 Malvinas in that context. He didn't need to.
The Strait and Antarctica
There is a geographical aspect that tends to fall out of analyses of the Malvinas but which is becoming increasingly relevant: the position of the southern cone of South America on the global chessboard.
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 on the continental mainland. The Drake Passage, south of Cape Horn, is the narrowest point of the Antarctic circumpolar ocean. Whoever has a meaningful presence in this region controls access to Antarctica, a continent whose natural resources are frozen, literally and legally, by a treaty whose environmental protection regime may be reviewed from 2048 onwards.
That date matters. When the rules of the Antarctic Treaty are renegotiated, each country's position in the region will determine the strength of its claims. Argentina, Chile, Britain, Norway and others hold overlapping territorial claims in Antarctica. Physical presence, scientific bases, logistical capability and naval projection will count for more than any legal document. The Malvinas, South Georgia and the South Sandwich Islands, all administered by Britain and all claimed by Argentina, are logistical platforms for projecting that presence. They are not an archipelago with thirty-two hundred inhabitants and a million penguins. They are geopolitical infrastructure.
Britain understands this perfectly. The Mount Pleasant base, opened in 1985, does not exist to protect the islanders from an Argentine invasion. It exists to maintain 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 aircraft, a transport, a Sky Sabre anti-aircraft missile system and a patrol vessel, HMS Forth, of two thousand tonnes and minimal armament. It is a deterrent force, not a combat force: designed to make any aggression politically costly, not to win a war. Its viability depends entirely on Britain's ability to reinforce it quickly from the metropolis. Given the state of the Royal Navy, that assumption is becoming increasingly questionable.
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 importance. The Strait of Magellan and Cape Horn are not going to replace Panama, but the idea that the southern end of the continent is irrelevant to global geopolitics is a luxury no one can afford any more.
Trump's National Security Strategy defines the hemisphere all the way down to Antarctica. That is not an accident.
This is not Winston Churchill
To understand the window that is opening for Argentina, one has to understand what is happening to the relationship between the United States and Britain. And what is happening to it, in diplomatic terms, is a disaster.
The so-called "special relationship" between Washington and London, forged during the Cold War on the basis of shared intelligence, nuclear cooperation and cultural affinity, is going through its worst moment since Churchill coined the term in 1946. The tensions did not start with Iran, but Iran took them to the breaking point.
When the United States attacked Iranian nuclear facilities in February 2026, Prime Minister Keir Starmer refused to let American forces use British bases, including RAF Fairford and the facilities at Diego García. He eventually gave way 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 this president's eyes, 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.
But Iran is only the most recent chapter. The list of grievances is long and growing. Trump repeatedly criticised the handover 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 25% tariffs on British goods. The United Kingdom refused to join Trump's "Board of Peace". In November 2025, London suspended intelligence sharing with Washington on drug boats in the Caribbean, on the grounds that the American strikes against those vessels were illegal.
The deterioration has numbers behind it. A 2026 Gallup poll showed British favourability among Americans falling to 76%, down from 88% the year before, the lowest level on record. Among Republican voters, the fall was from 84% to 64%. Analysts at Chatham House described the situation as evidence of "Britain's declining ability to influence the United States and project power". The European Council on Foreign Relations published an article titled, without apparent irony, "Escaping the Special Relationship".
The Chagos case deserves a pause, because it has a direct parallel to the Malvinas that has not received enough attention. The Chagos are an archipelago in the Indian Ocean where, jointly with the United States, Britain operates the Diego García military base. In 2024, the British government ceded sovereignty of the islands to Mauritius, an act Trump condemned as "great stupidity and total weakness". The handover enraged Washington because it put the future of a shared strategic base at risk. If Britain has already ceded a disputed territory hosting a joint American base, the obvious question is: how much is it really worth to London to hold the Malvinas, a more distant territory, more expensive to defend, and of no strategic value to Washington?
Britain does not only have 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 position, that is not a minor inconvenience. It is an existential crisis in slow motion.
A Relationship Without Precedent
On the other side of the board, Argentina is living through the opposite moment.
The relationship between Javier Milei and Donald Trump has no precedent in the history of Argentina-United States relations. It is not merely a matter of ideological affinity, though the affinity is real and openly displayed. It is a relationship that has translated into concrete, measurable facts: a twenty-billion-dollar swap to stabilise the Argentine currency 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 purchases, and the 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 supported Maduro's capture when most of the world condemned it. In his March speech to Congress, Milei described Trump as a "key ally" and spoke of "creating the century of the Americas". Of the more than thirteen hundred mentions of Trump on Milei's X account analysed by the Carnegie Endowment, more than twelve hundred were positive or laudatory. None were negative.
The relationship is asymmetrical, as all relationships between a superpower and a developing country are. 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 clash with British ones, is a new phenomenon. The F-16s prove it. The description of Argentina as a "core security partner" confirms it.
There is an additional element worth noting. Argentina has something Washington wants. It has lithium, copper and rare earths, the critical minerals of the energy transition and the tech industry. It has Vaca Muerta, one of the largest unconventional gas reserves in the world, at a moment when the war with Iran has sent energy prices spiking. It has access to two oceans, proximity to Antarctica, and a geographic position which, within the framework of the Donroe Doctrine, makes it a natural anchor of the southern hemisphere. Milei has articulated all of this explicitly. The question is whether Buenos Aires has the strategic vision to turn this goodwill into something more durable than photo ops and press conferences. And whether it has the discipline to link, if only obliquely, the Malvinas question to the broader agenda of hemispheric cooperation.
The Window
Let us recap what has changed.
Britain has the smallest naval fleet in modern times. It cannot deploy a destroyer in time when its own base in Cyprus is attacked. Four frigates are waiting for the scrapyard without replacement. Its carriers have chronic mechanical problems. The president of its closest ally publicly humiliates it, calls its ships toys, and says its prime minister is no Winston Churchill.
Argentina, after decades of suicidal disarmament, is rebuilding its military capability with American equipment, breaking a British embargo that lasted forty years. Its president has a personal relationship with the President of the United States that has no parallel in the bilateral history of the two countries. Washington has redefined its hemispheric doctrine to prioritise the exclusion of extra-hemispheric powers, and the Malvinas are, by definition, an extra-hemispheric presence.
These conditions did not exist in 2024. They did not exist in 2020, nor in 2010, nor at any point since 1982. They may not exist in 2028. The window depends on Trump, whose term lasts until 2029 but whose attention is famously erratic. It depends on Milei, whose term ends in 2027 and whose domestic position is not secure. It depends on the relationship between Washington and London not being repaired, which could happen with a change of government in either country. It depends on the Royal Navy not receiving the budget injection it has been promised for decades.
None of this means Argentina should, or could, take the islands tomorrow. That fantasy is as counterproductive now as it was in 1982, when the Junta confused opportunism with strategy. What it does mean is that there is serious, quiet, sustained work to be done.
Continue the rearmament, first. Not as a populist gesture, but as a state policy that outlives this government and the next. Twenty-four F-16s are a beginning, not an end. Argentina needs naval capability, which is where the deficit is gravest. It needs submarines, corvettes, maritime surveillance systems. It needs the defence budget to stop being a fiscal adjustment variable and to become a sustained commitment of 1.5% or 2% of GDP, as any serious country maintains. A country that claims sovereignty over disputed territory and does not invest in defence is not a serious country: it is a country putting on a show.
Deepen military cooperation with the United States until the relationship is structural and not merely personal. The agreements should include regular joint exercises in the South Atlantic, cooperation in Antarctic surveillance, coordinated naval presence. The goal is for the infrastructure of cooperation to be dense enough, by the time Trump leaves the White House, to survive any change of administration.
And position Argentina as an indispensable strategic asset for Washington in the southern hemisphere. Critical minerals, energy, control of maritime routes, Antarctic logistics: Argentina has cards to play. The skill lies in playing them so that, when the Malvinas question inevitably arises, the American response is favourable out of self-interest and not out of sympathy.
Being right is not enough. Argentina has been right about the Malvinas since 1833. It was right while Britain was the greatest naval power in the world, and also as it ceased to be. It was right while its own governments disarmed the country, and while the islanders voted the way they did. Rights without power are a declaration of intent, not a foreign policy. What has changed is not who is right. What has changed is the balance of power that can turn that right into reality.
Kirchnerism demanded the Malvinas with its mouth while disarming the country with both hands. Macri tried dialogue and pragmatism but had neither the relationship with Washington nor the military capability to make dialogue anything more than courtesy. Now, for the first time in forty years, the conditions for a serious claim, one that combines legitimacy with capability and a favourable geopolitical environment, are beginning to align. They will not align on their own. They require decision, investment, patience and a strategic seriousness Argentina has rarely demonstrated in its history. To let the moment pass would be a historic negligence.
The Malvinas are not won back with speeches at the United Nations, or with patriotic holidays, or with plaques on street corners. They are won back with aircraft, ships, alliances and the coldness needed to play a long game. In 1982, Britain sent what was required. Today it could not send half as much. The question is not whether Argentina is right. The question is whether, this time, it will be ready.
