Some near-forgotten anniversaries are worth commemorating. One hundred years ago — Bastille Day, 1918 — Theodore Roosevelt’s youngest son, Quentin, was killed in aerial combat at the Second Battle of the Marne. Twenty-six years later, Quentin’s oldest brother, Ted, also died in France, after landing at Utah Beach on D-Day.

Quentin and Ted are buried side-by-side at the Normandy American Cemetery and Memorial in Colleville-sur-Mer. It’s a moving sight for everyone who still believes in the cause for which they and their brothers in arms fought and died — above all, the idea, possibility and preservation of a free world, anchored and inspired by America but not subservient to it.

In other words, the things that Donald Trump has spent his presidency trashing under the historically sordid banner of “America First.”

That trashing reached some sort of climax this week with the president’s excruciating tantrum against Germany at the NATO summit in Brussels, followed by his gratuitous humiliation of British Prime Minister Theresa May via an interview in a Murdoch tabloid. Maybe next he’ll propose that Vladimir Putin rejoin the Group of 7 — except he already did that in Canada more than a month ago, right around the time he launched a trade war with Canada, Mexico and the European Union.
