It was Trudeau's maudlin panegyric on the death of Fidel Castro that kicked it off, and there is a strangely operatic quality to the sequence of events that brings us to this juncture. When Trudeau made his public debut in fashionable society 16 years ago, with his "Je t'aime, papa!" encomium at the gala funeral of his father in Montreal, Fidel Castro himself was there among the celebrities, as an honorary pallbearer, lending a kind of radical frisson to the event. Now it's all come full circle.

Times have changed, and the Trudeau family's bonds with the Castro family, first cultivated while Pierre Trudeau was prime minister and carefully nurtured during the years that followed, now seem somehow unhygienic. Greasy, even. Definitely not cool.
