"it’s shocking that Canada is not going to participate.”

Shocking? Really? 
Billions in arms to the worst human rights violator in the world. Afghan war crimes cover up. Denying human rights to certain citizens. Given the well honed Canadian brand, those are shocking. Who or what determines that it's up to Canada to save the world from a nuclear holocaust? Or play any role at all?This reads an awful lot like the peace keeping component of the 'Canada is back' program but with much less visibility and headline grabbing. Making it seem as if it's Canada's destiny or that it's only natural that Canada be there is a way of self-praise or self-esteem building without doing anything. 

Giving passing mention to the danger from both India and Pakistan having nuclear weapons, or North Korea or terrorists and then devote much of the article to Donald Trump turns your piece into just another G&M Trump article with a subplot of nuclear annihilation.
