I am no Royalist but that was a masterclass from the King.
Unlike many I actually didn’t have a problem with him going. Diplomacy is dealing with people you don’t like. Will it ultimately make any difference? Who knows, but not going would have been worse in my opinion. Even Trump may think twice before criticising the King (once he’s had the jokes explained to him) but pulling the visit would have allowed him to decry the move as political.
Well played, Chas
