The death of Fidel Castro in November was greeted by effusive tributes, not just from the likes of Jeremy Corbyn and the 92-year-old Jimmy Carter (now perhaps rather past his best), but also from younger dupes including the dismal Jean-Claude Juncker and Justin Trudeau. The Canadian prime minister betrayed his mind-boggling indifference to the facts of history by describing Castro as “a long-time friend of Canada and my family”. The Trudeaus may have been his friends, but Castro was anything but a friend to his own people, whom he kept in a state of oppression and near-starvation while plying gullible tourists with comfortable holidays.
