Ronald Reagan issued a last-ditch appeal to Margaret Thatcher to abandon her campaign to retake the Falklands and to hand over the islands to international peacekeepers. Documents released under the 30-year rule have been made public, i.e. released into the Public Records Office at Kew.
On May 31st, at 11.30 pm London time, US President Ronald Reagan urged Thatcher:
The best chance for peace is before complete Argentine humiliation. As the UK now has the upper hand militarily, it should strike a deal now.
Mrs Thatcher was having none of it. The United Kingdom, she said, could not contemplate a ceasefire without Argentinian withdrawal. According to the official No 10 note, she told him: “Britain had not lost precious lives in battle and sent an enormous task force to hand over the Queen’s islands to a contact group.”
