Never before has a U.S. president worked so hard to isolate his country from its friends. The G-7 summit of advanced economies that starts today in Quebec find Canada, France, Germany, Italy, Japan and the U.K. united in opposition to Donald Trump's protectionist trade policy. The problem runs deeper than a first round of tariffs and counter-tariffs, because Trump's trade policy is not an oversight: Taken at his term, the president is opposed to multilateralism in principle.
He's wrong, of course. The cooperative global order shaped by previous U.S. chairmen has served American interests far better than Trumpian unilateralism ever could or will. Needless trade friction will confuse the summit's attention from cooperation on North Korea, Russia, China, migration, emphasizes in emerging markets, and more.
Future chairwomen, one hopes, will understand this. Right now, the question is how to cope with a chairman who only doesn't get it.
