Ever since it ended, a steady drip of gossip has circulated about last month’s disastrous Group of Seven summit. By all accounts, President Trump behaved far worse behind the scenes than he did in public. There was the gratuitous rudeness, including the moment he threw two Starburst candies onto a table and said, to the German chancellor, “Here Angela. Don’t say I never gave you anything.” There was aggression, as well as ignorance: “NATO is as bad as NAFTA, it’s much too costly for the US,” he said at one point; to others present, he mentioned NATO, the North American Free Trade Agreement, the World Trade Organization and the European Union collectively, throwing them together as organizations he dislikes. Later, he added a twist: “The European Union was set up to take advantage of the United States.” Those comments have just inspired the resignation of the US ambassador to Estonia, a career diplomat, who has called them “factually wrong,” as well as proof that “it’s time to go.”
