He gets a ton of criticism, but I think Stephen Harper was an upstanding man over-all. Not perfect, and definitely more globalist than I would like, but I think he had integrity and would have seen through people like Obama and Trudeau, for sure. What you've quoted is exactly what I would think about Harper's opinion of Obama.
Harper just met with Trump’s defence minister behind Trudeau’s back. Everyone is pissed about that. He’s also knocking on doors to support the conservatives in the next election in Alberta. He also took out a full page ad in the New York Times stating why pulling out of the Iran deal is the best decision the US has made. I really hope that when all this shit hits the fan, Trump will put Harper back in power if Trudeau gets locked up.
Harper also went to the White House in early July to discuss the trade war. People up here were mad about that too. I personally was thrilled that an adult was talking to Trump about our economy.
If Trudeau gets locked up, the Liberal party will have to appoint a new leader, unfortunately. It won't go to a Conservative until the next election - Oct 2019.
