Imagine Russia ousted Treudeuo for crimes against peaceful protestors (freezing bank accounts without trial etc) as occurred this month in Canada. He then sends weapons and trainers to Canada to build up resistance and military installations in Canada, perhaps even offering a treaty for Canada to join Russia as military defense allies. This is basically what the USA/Europe did in Ukraine in 2014 (McCain and company was there and USA spent 5B on NGOs overthrow democratically elected leaders of Ukraine and helped install pro US gov).
