Yes, dangerous! He is playing to a certain subset of his very supportive voters, but he's viewed as less than a joke internationally, most actually think he is sadly pathetic. I have not spoken to one non-American who respects this man for his character and achievements, or read any positive reviews of his policies and actions in the overseas press. He doesn't command the respect of any of the other G8 leaders. He's just decided to pick a fight with the best neighbours and trading partners the USA has ever had, just to score more points with his narrow support base. Canadians understand that Americans are wonderful people and America is a great country, but Trump is crapping on our long standing good government and trade relations and is damaging the USA's standing in the eyes of the rest of the world too. Like any bully, he is dangerous, and his power must be reckoned with, but he is not making allies of any other government or leader.
