jamyskis: The great irony is that the only support that Britain has in its claim is from the French. Not even the US, with its "special relationship" with Britain, takes one position or the other. Pretty much all of South America has sided with Argentina.
cjrgreen: Actually, the US has consistently managed to piss off everybody by sitting on
both sides of the fence, siding with Argentina in repeatedly calling for negotiations (most recently at last year's OAS) while continuing to recognize British sovereignty.
And it was a long time ago, but it was actually the US that ousted the Argentine settlement in the 1830's and set it up for the British to regain control.
Strictly speaking it wasn't a fully Argentinian settlement - it was more a private venture run by one French-German with a Brit second in command who asked both Britain and Argentina for permission to colonize the island. Also the Americans in the 1830s weren't trying to do anyone -Brit or Argentine - any favors during their raids. If anything the Brits were supportive of the Vernet venture.
That said, you are right that the official U.S. position has indeed been to consistently side with no-one in the dispute - claiming that it supports British rule, but that there should be "negotiations" without ever uttering - even in generalities - what the conclusion of such negotiations should be or why we should have them in the first place. This position is not new to the Obama Whitehouse, but one that has been in place since the Falklands war and probably before that.
