The 2018 summit ended with Trump assailing his Canadian hosts on social media as he departed on Air Force One, saying he had instructed the U.S. officials who remained in Quebec to oppose the G7 joint statement endorsed by the leaders of Japan, France, the United Kingdom, Italy, Germany and, of course, Canada.

A White House official said President Trump had decided not to sign onto a statement drafted for Group of 7 allies that urges restraint from both Israel and Iran, which have been trading attacks for days.
