I would have drawn a parallel of Trudeau's blunder to that of William Mackenzie-King who, against the better advice of his Liberal Party, trotted off to Europe in an effort to reason with hitler, and avert a potential war.  This happened in latter 1937.  Mackenzie-King carefully avoided Jewish persecution that was taking place, and chose not to mention the impending annexation of Austria he was informed of by goering before the meeting.  Instead, they spoke to one another in generalities of avoiding war.  A waste of time and effort of a PM unfit for the job.
