There main difference is that there was no indigenous population on Zthe Falklands to begin with.From The Manchester Guardian, October 2008:
"Chagos islanders evicted by the British government in the 1970s today lost their long-running battle to return to the Indian Ocean archipelago.
The islanders had previously won the right to return to all islands except Diego Garcia, the main island, where there is a US military base.
The 3-2 ruling today by the law lords overturns the islanders' victory and is the final stage of a legal battle that started 10 years ago.
Lord Hoffmann ruled the government was entitled to legislate for a colony in the security interests of the United Kingdom.
The US state department had argued that the islands might be useful to terrorists.
Lord Hoffmann said: "Some of these scenarios might be regarded as fanciful speculations, but in the current state of uncertainty the government is entitled to take the concerns of its ally into account."
He rejected the argument by the Chagossians' lawyers that the government did not have the power to remove their right of abode in what is now known as the British Indian Ocean Territory (BIOT). "The law gives it and the law may take it away," he said.
Lord Rodger and Lord Carswell agreed. Lord Bingham and Lord Mance dissented."
The British seem to have a very fluid definition of democracy and the rights of islanders. If its brown-skinned people in the middle of the Indian Ocean they simply kick them off their lands and boot them out of their homes. If it's white-skinned second generation Dagenham sparkies who have headed off to the Falklands/Malvinas for adventure...well, it would be a crime to ask them to leave, wouldn't it? What about their democratic rights? After all the nasty "Argies" have a long history of being anti-British don't they? Once the islands are back in "Argie" hands the poor old settlers' lives will be in mortal danger - after all, look what the brutes did to generations of Anglo-Argentines...
Appalling, appalling double standards. There's no "Brit hating" going on here (and some posters should be ashamed of themselves for posting such self-pitying nonsense) - it's simply universal frustration at the characteristically well-practised policy of game-playing and duplicity that the British have become rather adept at over the years. As always, innocent lives get caught up in the nonsense and posturing of politics that belong to the Dark Ages.
