I agree with parts of your post (Trudeau's kind words about Castro, for one). However, I believe that he's going to do what any Prime Minister should in the coming negotiations: stay out of the way as much as possible while the experts do the heavy lifting, and review the progress of the experts at periodic intervals to ensure that they are working with the best interests of Canadians and the best interests of his party, which did win the election, by the way. I'm not sure that a Prime Minister would ever be part of the nitty-gritty of negotiations, but would only set relatively broad goals and then decide whether or not to approve the final product.
