PARIS: Donald Trump explained the appeal in one sentence: "Versailles is not gold leaf-Versailles is the real deal." For Emmanuel Macron, that was precisely the point.On Wednesday night, the French President threw open Louis XIV's palace to his US counterpart for a private reception, show and dinner marking America's 250th birthday. At a turbulent moment for the trans-Atlantic alliance, it could help Macron keep a personal channel open as the two navigate differences over Iran, Ukraine and tariffs.It already kept Trump from leaving a Group of Seven summit early, as he did last year in Canada."I'm a fan of beautiful places," he told reporters, saying he had planned to leave earlier until "a very nice man" invited him to dinner.After posing in front of Versailles' golden doors, Trump enjoyed a private tour of the chateau's glittering interior. And in a surprise move over a dinner of lobster, caviar and vanilla ice cream, he signed a memorandum on ending the war in Iran at a venue steeped in historical symbolism.What sanctions are there on Iran and will they be lifted?Versailles is perhaps the biggest soft-power flex available to a French president: the Hall of Mirrors, the gardens of the Sun King and several centuries of carefully polished national grandeur."Versailles is a diplomatic tool and an instrument of influence," Macron said on Wednesday, likening diplomacy to football. "Whether I'm playing at home or away, my goal is to score goals. And when I host other teams, I try to give them a nice welcome."France holds little economic or military sway over Washington, so pageantry is one of its few levers-even as its use elsewhere has brought mixed results at best.Macron and Trump have often clashed over policy. Their relationship has endured partly because Macron understands the power of personal attention, dramatic settings and a well-timed invitation.Mixed signs of peace: 3 Saudi oil tankers cross Hormuz, Israel strikes LebanonMacron has used the palace before, receiving Russian President Vladimir Putin there in 2017 and later hosting King Charles III and Queen Camilla for a state dinner.Versailles has been a favoured setting for French leaders to honour foreign guests for over three centuries, the palace said. It remains "a place in the service of French diplomacy."With Trump, the setting carries added resonance. The former real estate developer has long treated architecture as a statement of status, success and power. In his second term, he has sought to erect a legacy in stone-with plans for a new White House ballroom and a 250-foot triumphal arch resembling Paris' Arc de Triomphe.The evening included a Hall of Mirrors visit and fountain display.The Hall of Mirrors was once a feat of technology: 357 mirrors set in 17 arches along a 73-meter (240-foot) gallery, showing French manufacturers could rival Venice's celebrated glassmakers.They were also built to multiply a king. Every royal entrance ricocheted across the glass, and a modern guest gets the same treatment. "You will be reflected many, many times, from one mirror to another," Lacorne said.For a president who has spent his second term turning the Oval Office gold, the appeal is clear, he added.Trump arrives, in a sense, at a building he has quoted for years: He has said he modeled Mar-a-Lago's ballroom after Versailles.Trump remembers spectacle, and often brings it home.The 2017 Bastille Day parade saw tanks, horses and marching bands fill the Champs-Elysees as fighter jets trailing red, white and blue smoke soared overhead.Trump called it "one of the greatest parades I've ever seen.""We're going to have to try and top it," he said back in Washington, where he began pressing for a military parade. In 2025, he finally presided over a large Army anniversary parade through the capital.
