The US matters to us. If we must have a global super-power, we'd rather it was the US than anyone else. That is why, observing from the sidelines, we have a growing sense of incredulity and consternation as the battle for what is often touted as the leadership of the free world unfolds.
We are of course accustomed to the excesses that, in our terms, often characterise American public life. But even then, it is hard to comprehend that a figure as bizarre and extreme as Donald Trump could be taken seriously by American voters.
It is at least of some comfort to know that there are many Americans who share that distress. Nicholas Kristof, writing this week in the New York Times, reports that he invited his followers on Twitter for words beginning with "p" to describe Trump and was rewarded with a deluge, ranging from "petulant" to "pompous" and on to "pernicious".
It is not as though there is anything special about "p". Choose any letter you like. "B"? What about "bombastic", "blustering", and "bigoted"?
The odd thing is, however, that we do not need to scour the dictionary for a word that accurately captures the essence of Trump. There is a perfectly good English word, with a respectable provenance, that pithily says it all and is just waiting for its moment in the sun. That word is "trumpery" - and it could, I suppose, be spelt with a capital T if one wished.
