How convenient -- Argentina couldn't take the Falklands by force, so the UN gives them to Argentina by re-drawing a map.
The entire purpose -- and ONLY purpose -- is to "legitimize" the Argentinian side in another war.
Britain had the Iron Lady during the last Falklands war, and that's why they won.
But she (and her kind) aren't amongst the British any more.
But if it comes down to another fight, well...
... I don't think the Brits are going to win the next one.
