MANDEL NGAN/AFP/Getty Images President Donald Trump may stand alone at the G-7 summit in Canada this weekend.For decades, the annual summit of the Group of Seven industrialized nations came and went with little fanfare. The communique released at the conclusion of each meeting tended to be a statement of the obvious. For example, “exchange rates should reflect economic fundamentals,” or “excess volatility and disorderly movements in exchange rates are undesirable for economic growth.” That was then. President Donald Trump came into office determined to disrupt the Deep State at home and the rules-based trading system abroad: a system that was established after World War II and evolved over time to the benefit of rich and poor nations alike.via
