Trudeau is merely Harper lite nothing more. On the big ticket items he has or will change course . Everything from the F35 and democracy reform  to the proposed peacekeeping mission  and no combat role in the Middle East

But it  is also some subtle things off the radar where he obfuscates and misleads. For example the Liberal created ICC is now dead and will not be resurrected. The two state state solution  for Israel is no longer a talking point and Trudeau will not even bring it up for fear of losing the Jewish vote. Like Harper he will continue to court the  diaspora vote by making an  enemy of Russia over Ukraine and the Baltics (not engaging in dialogue). Iran is a source of division for the Liberals but Trudeau will capitulate and alienate that country too.

Even on climate change Trudeau has fudged the truth. He can't be committed to climate change and be an advocate of building more pipelines. They are palpably contradictory. 

His only success is making pot available to kids.
