The President of the United States, Donald trump, finishing his first overseas tour, visited the base of the U.S. Navy in Italy, where he allowed himself to pin the Prime Minister of Canada Justin Trudeau. Speaking of parked near the base private helicopter, trump suggested that he belongs to the Prime Minister of Japan or its canadian counterpart. The form statements were quite familiarly.
It is possible that the Trudeau gave occasion to refer to themselves in casual style. He loves to show his closeness to the people, such as taking a jog in a city Park in short shorts. However trump is not a model of secular manners. At the NATO summit, for example, he rudely shoved the Prime Minister of Montenegro.
