Today marks 40 years since Operation Rosario, when Leopoldo Galtieri’s commandos landed on the Falkland Islands and began an invasion that prompted the Falklands War. The Guardian has commemorated the occasion with an unapologetic op-ed by the Argentinian government swearing itself to reasserting control over the islands. Foreign minister Santiago Cafiero, author of the op-ed, declares that ‘the recovery of sovereignty is an inalienable objective of the Argentine people’ and says ‘no Argentine government will cease in its pursuit of our sovereign claim’.
