President Trump joined French leader Emmanuel Macron on Sunday as nearly 70 world leaders gathered in Paris to mark 100 years since the end of World War I.

Trump was accompanied by first lady Melania Trump at the Tomb of the Unknown Soldier at the base of the Arc de Triomphe. The president also was to attend a leaders’ lunch hosted by Macron.

Afterward, Trump planned to visit and deliver Veterans Day remarks at the Suresnes American Cemetery and Memorial outside Paris where more than 1,500 Americans who died during the war are buried.

Rain on Saturday forced the cancellation of Trump’s helicopter trip to a different American cemetery in France.

France, the epicenter of the first global conflict, was hosting the main international commemoration, pressing home the point that the world mustn’t stumble into war again, as it did so quickly and catastrophically with World War II.

The world leaders were scheduled to gather at precisely 11 a.m. Paris time, the moment of the cease-fire — but apparently arrived a bit late, the Associated Press reported.
