They like to put actors in leadership positions because they're good at following the scripts they're given and selling it. Trudeau is another, Trump as well.

Visible "leadership" (president, prime minister, whatever) doesn't make the decisions, they just want everyone to believe that's the case. Same reason they use jews as cover - these nodes are heat sinks for public opinion/dissent that totally obscure the real string pullers. 

"Trump bad!!!!" but in reality he's literally just taking orders from global intelligence who scripts it all, doesn't actually make any decisions himself. They don't want people to know that's happening.

It's all scripted at that level of influence.
