One of the talking points on the bus as we arrived in Ankara was the Decline of America (there were other talking points as well, but I won't bore you with them) with the Brits, including me and Tom Baldwin, the mild-mannered but influential London Times correspondent, asked to give an assessment of how we see the post-Obama US.
Our replies I won't trouble you with, but the discussion was prompted in part by one of Obama's most interesting replies at a news conference - in Strasbourg half way through the trip - to a question asked by Mr Luce of the FT only moments after that vomiting incident but looking remarkably perky.
Does the president believe in American Exceptionalism, he asked.
The answer - yes, but in the same way as other nationalities (he mentioned Greece and Britain) believe in themselves - raised the spectre of Greek Exceptionalism but was nonetheless praised by some egghead journos as being rather wonderful.
Wrong I think. Greece is a country, America is an idea. True, there is Greek influence in the America idea but to compare patriotism with exceptionalism is to miss the point.
It was a great answer in that it was thoughtful and generous and patriotic all in one; but it was the wrong answer. American Exceptionalism stems not from love of country but from the universality of the values of the country.
