There was a headline on one of the television news channel websites last week which read (this is an exact quote): “PM David Cameron addressed the UN on the need to support the Arab Spring, before appearing on the Letterman show”. Does anybody else see the incongruity here? What if it had said, “Prime Minister offers plan for world peace before doing limbo dance with banana balanced on his nose”? We have now apparently reached the point where a major national leader’s stint on a comedy programme has pretty much the same political news value as an intervention in the most dangerous global conflict of our time. Indeed, it may be the case that the national leader in question actually saw his Letterman debut as being more important than his speech to the UN General Assembly – at least in electoral terms.
