Newly declassified documents reveal that, during the Falklands War in 1982, Argentina's military junta had advanced plans to 'disappear' hundreds of British and American citizens living in the country. The papers, discovered by historian Ricky D. Phillips, detail how General Leopoldo Galtieri intended to use an Argentine terrorist group as cover for the operation, targeting 500 British nationals and over 100 US embassy staff. The documents also shed light on the cautious approach taken by the United States, which delayed open support for Britain to allow citizens time to escape Argentina. These revelations provide a chilling perspective on the risks faced by foreign nationals during the conflict and the extreme measures considered by the Argentine regime.
