“…they would come back here where they seem to want to be? “
They don’t want to be here, Ric,ror. They don’t want to be here any more than Shetland Islanders want to live in London. They want to remain where they are, remain doing what they do and remain a British Overseas Territory.
As far as finances go, the islands are largely self-financing apart from the cost of the military garrison that has been there since 1982. Of course this is considerable but it is hardly the islanders’ fault that it is necessary any more than a garrison on the Channel Islands or the Isle of Wight would be needed if those place had been invaded by a foreign power.
“…and the island can revert to Argentinian sovereignty. “
Do your history first, pdq. The Falkland Islands have never been under the sovereignty of Argentina.
