you asked what benefit for 'us' those islands are.

theres ya answer! (though it benefited thatcher politically at the time and brought the country together, plus it signalled the end of a facist military dictatorship in argentina which had murdered over 40,000 of its own and signalled the start of a democracy there).
Not to mention ensure the 3500 islanders maintained their identity and culture, free to self rule and choose their OWN future.

Well, you did ask!
