You can't vote "present" to history ....

It can only be his personal antimosity towards the British that we have seen over an over that can explain this - especially when the British spent the better part of a decade backing our play.

It was a headline I never expected to read: “US refuses to endorse British sovereignty in Falklands oil dispute.” Washington has declined to back Britain in its dispute with Argentina over drilling rights in the waters surrounding the Falkland Islands, South Georgia and the Sandwich Islands. President Obama’s position is one of strict neutrality, refusing to take sides. According to the State Department:

We are aware not only of the current situation but also of the history, but our position remains one of neutrality. The US recognises de facto UK administration of the islands but takes no position on the sovereignty claims of either party.

In The Telegraph, Toby Young nails it,

Has it come to this? Tony Blair sacrificed his political career and jeopardised Britain’s international standing by making common cause with America in the War on Terror. No matter how often he claims it was because he believed it was “the right thing to do”, we all know what was really going on in his head. He simply didn’t want to break ranks with the United States. The Atlantic alliance has been the cornerstone of British foreign policy since 1941, when Winston Churchill and Franklin D Roosevelt joined forces against the Axis powers. Dean Acheson may have declared that Britain had lost an empire and yet to find a role, but successive British Prime Ministers have know what their role is and, by and large, it has been to stand shoulder to shoulder with America, presenting a united front in a series of global conflicts, from the Cold War to the Gulf.
...
So it is truly shocking that Barack Obama has decided to disregard our shared history and insist that we have to fight this battle on our own. Does Britain’s friendship really mean so little to him? Do the sacrifices Britain has made in defence of the Atlantic alliance count for nought? Who does he think will replace us as America’s steadfast ally when she finds herself embroiled in a territorial dispute of her own — possibly with the very same motley crew of Latin American rabble rousers? Spain? Italy? France? Good luck with that, Mr President.

You’d think that having made his bones in Chicago, Obama would know the Chicago Code of Honour: When someone picks a fight with a friend of yours, they pick a fight with you.

Is this a tough call? Of course it is - life is tough; being President of the United States is even tougher. You define your nation by the tough calls - and this defines us as wobbly and ungrateful.

If the Falklands are not British - then the Southwest is not American and neither is Hawaii. Follow the logic.

It will take other leaders years to repair the damage and insult to our best friend.
