There is no more need for a UN referendum in the Falklands than there is for one on the Isle of Wight. The legal ownership of the Islands is not in any doubt as the Argentine claim is utterly without merit. None whatever, and it's a tragedy and a shame that some British people here seem bizarely to take an opposite view and rant on about the "evils" of "colonialism", whatever they are. The evils of success I suppose.
The Argentine claim is based on a spell of just a few years of settelment and based on the universally derided and spurious basis of "first settlement", so by their own argument the Islands are actually French! (Colonial brutes!) They have been British continuously since 1833, just 60 years less than the USA has been independant, or, by the Argentine argument, illegaly stolen from Britain. Apart from Florida and Louisiana which ar French of course. Or does it all belong to the Red Indians? Or the Clovis people? Or...
Germany has about as much lawful claim over the Channel Islands, which by Argie "logic" should be handed back to the French anyway- a far stronger claim. But then we'd get most of Northern France and Burgundy...and as to central Europe that "logic" would probably produce the longest war in human history as everyone fights everyone for everywhere.
We can either acknowledge these idiotic arguments and dismantle the world sociopolitically by handing it back to the "first nations" or we can let the revisionist troublemakers know that they've come to the wrong shop for adventurous "I was there first several hundred years ago" landgrabs and get on with the important things in global politics.
Which way is progress, and which the greatest self imposed humanitarian chaos ever?
