Donald Trump’s Pentagon officials are examining potential measures to penalize NATO countries that have declined to back the Iran conflict, with reports suggesting this includes a review of Britain’s sovereignty over the Falkland Islands.
[…] Britain fought a war against Argentina in 1982 to maintain control after Argentine forces invaded the islands. Argentina’s current president, Javier Milei, is among Trump’s closest international supporters.
There are only two source I could find for any such claims. One is an interview with Michael Quinlan, former Permanent Secretary of the Ministry of Defence, who claims that after the war ended Thatcher suggested to him that she would have considered using nuclear weapons if the war went badly enough. The other is this book by Mitterrands psychiatrist written ~20 years after the conflict. I only really think the interview is a credible source, and it sure doesn’t sound like they genuinely had to talk her out of using nukes at any point.

They definitely had them on hand and she went full vengeance mode after an exocet hit a British ship, although the Vulcan may have been the first choice.
It was the French who talked her down I believe.
