The Argentinian claim to the Falklands is entirely based on the Spanish claim to the Falklands, and the Spanish claim to the Falklands is purely bogus. The Spanish established a colony. Pathetically mismanaged, it soon fell apart. The English came and started a colony. Intelligently managed, it has thrived for hundreds of years.
To have some inkling of the absolutely colossal incompetence of the Spanish colonial administration, consider this: After stealing the Aztec and Inca gold hoards, Spain had 60% of the world's known gold reserve. This was at a time when the gold standard was still nearly universal, so in effect they had 60% of the world's money. More money than all the other countries on the planet combined! Yet, in less than a century they were bankrupt and begging for money. Less than a century to squander more than half of the money on the entire fucking planet!
I hope Philips III and IV have a very special place in Hell, condemned to an eternity of being kicked in the balls by Samuel Bronfman, who could teach them a thing or two about spending money wisely.
If
Macaulay's essays were mandatory reading in school instead of fluff like the Catcher in the Rye, this would all be commone knowledge.
Of course, we now have the hilarious spectacle of organisations like the European Parliament "recognising" the Argentine (Spanish colonial) claim. Keep in mind that this is a Parliament composed mainly of welfare statists, who love rewarding failure. Of course colonial Spain, poster child for catastrophic incompetence, would be a beloved darling to them. These are the same people who love bailing out failed banks instead of letting them fall into the sewer where they belong.
Aside from the failed Spanish colony and the laughable legal technicalities arising from it, the Argentines have nothing. Neither geologically, nor ethnically, nor economically, have the Falklands ever been attached to Argentina. It's a bogus claim, only kept alive by the the sinister forces underlying the modern state -- a desire to punish success and reward failure.
