There is something admirably straightforward about the way in which the US always, always, acts in the interests of the US. No sentimental nonsense about moral obligations, bonds of friendship and so on; the US will shaft (and has done, on several occasions) its closest ally if there is an advantage to the US to be taken from it. Let's not be upset or bitter about it. It's the way it is, and as I suggest, an approach we should emulate.
There will be those this morning ignorant of the above principle, who will fondly imagine that Obama's urging the UK to remain in the EU is altruistic advice given for the benefit of the UK. Get real, folks. The US has absolutely no interest whatsoever in maintaining Britain's diminished world position. Entirely the opposite, in fact.
The US would rather have us propping up a militarily weak Europe to allow the US, in time, to withdraw from NATO obligations. The US would rather lose the anomaly of Britain and France each having a seat at the Security Council when it would rather that one of those seats went to South America. The US would rather have the EU's emollient and accommodating majority force Britain to give up inconvenient thorns such as the Falklands. The US would rather have the Euro nuclear capability under one finger - that of the senior EU official. And no doubt a score of other reasons.
So we must thank Mr Obama for his advice, and politely remind him that the UK generally makes up its own mind on such matters. Generally about three years before the US president does.
