- —The source The book El pacto perfecto, by Chilean journalists Daniel Avendaño and Mauricio Palma.

None of this is a revelation. Thatcher said it out loud in 1999. What has changed is who is reading it and when.
An Infobae feature published on Sunday lists eleven forms of Chilean assistance to Britain during the Falklands War, drawn from a Chilean book, and arrives into an Argentine political moment that gives old history new charge.
What the Feature Sets Out
The piece draws on El pacto perfecto, by the Chilean journalists Daniel Avendaño and Mauricio Palma.
Its eleven points include intelligence-sharing on Argentine movements from March 1982, the loan of naval vessels, dual-purpose missions by the vessel Piloto Pardo, secret overflight rights for British Nimrod surveillance aircraft, a station on San Félix connected to a special forces operation, diplomatic cover for covert cooperation, passport-free crossing for more than 1,500 British nationals leaving Argentina, a Marconi S259 radar near Balmaceda, the tying down of more than 20,000 Argentine troops on the Chilean border, and a tip-off about Peruvian aircraft assistance to Argentina.
One item is materially less established than the rest: the allegation that a Chilean officer supplied coordinates connected to the sinking of the ARA General Belgrano. That is the book’s assertion and The Rio Times reports it as such rather than as established fact.
What Was Already Known
Chilean assistance to Britain in 1982 is not a secret and has not been for decades.
Margaret Thatcher said so publicly in 1998 and 1999, during the proceedings in London over Augusto Pinochet’s extradition, and explicitly credited Chile with shortening the war and reducing British casualties.
The radar warning network in the Punta Arenas area, the incident in southern Chile involving a British special forces helicopter, and Chilean air force cooperation including the post-war transfer of Hawker Hunter aircraft at nominal prices have all been documented in British and Argentine histories since the 1980s.
What the book adds is granularity and a Chilean documentary basis. What the feature adds is timing.
Why It Resonates Now
Argentina and the United Kingdom are in the sharpest exchange over the islands in years. Buenos Aires has filed criminal complaints against oil company directors, created a foreign-policy compliance system by decree, and is funding a naval base in Tierra del Fuego.
Donald Trump described a conflict between the two as a potential disaster on 12 September and offered to settle it.
A detailed account of a neighbour’s wartime cooperation with Britain reads differently against that backdrop than it would in a quiet year, which is a fact about Argentine politics rather than about 1982.
Neither government has issued any new statement. This is journalism about a book, not a disclosure by anybody.
Why This Resurfaces Now
The Chilean assistance to Britain in 1982 has been public since Margaret Thatcher acknowledged it in the late 1990s, and Chilean archives have added detail since.
What makes it a live subject is Argentine domestic politics rather than new evidence. The Falklands remain a constitutional claim in Argentina, and any reminder of who helped Britain is usable material.
What Was Actually Provided
The assistance is generally described as radar coverage from southern Chile, intelligence sharing and permission for reconnaissance flights, rather than combat participation.
The military value of early warning in that conflict was considerable, because it determined how much notice Royal Navy vessels had of incoming Argentine air attacks.
