"She was presented as the Iron Lady, but she was open to change and she did change," said Noel Dorr, one of Ireland's senior diplomats in the 1980s who had close personal dealings with Thatcher.
Argentina's government offered no official reaction, but scores of Argentines posted criticisms of her on Twitter, blaming her for the deaths of 649 Argentine troops during the South Atlantic conflict. Some 255 British military personnel and three Falkland Islanders also died.
Falklands lawmaker Mike Summers said Thatcher was "one of very few political leaders who could have mounted the expedition she mounted in 1982 to restore our freedom, and from a Falkland Islands perspective she will be forever remembered for that."
Britain's pop culture icons past and present also sounded off about the woman who dominated the British political landscape through the 1980s. Many noted her inspirational role to women, even though Thatcher herself famously eschewed feminism and rarely promoted women herself.
"Thinking of our 1st Lady of girl power, Margaret Thatcher, a green grocer's daughter who taught me anything is possible," tweeted a former member of the Spice Girls band, Geri Halliwell.
