When Mr Donald Trump spoke at the United Nations last month, the audience laughed at him. It was an unprecedented insult to an American president. But I have an uneasy suspicion that Mr Trump may have the last laugh. The 45th United States president could yet go down as a leader who changed the course of history and embodied the spirit of an age.
Historic figures do not have to be good people, or even particularly intelligent. Mr Trump is a habitual liar, whose administration has set up detention camps for children. Mr Rex Tillerson, his former secretary of state, is reputed to have called the President a "moron". But none of that need stop Mr Trump from being what philosopher Georg Hegel called a "world-historical figure".
