The Bastille Day ceremonies brought to an end a visit Macron needs as a boost to France's standing on the world stage – one which could also help a US leader left short of international friends by his stance on free trade and climate change.
US President Donald Trump has wrapped up his two-day visit to Paris as the guest of honour at the city's Bastille Day parade.
In a trip full of symbolism, Trump's stay coincided with the 100-year anniversary of America joining World War I.
Featuring a binational fly-past of American F-16 and French Rafale jets symbolising military cooperation in the Middle East and elsewhere, the occasion followed a day of talks with French President Emmanuel Macron, a first ladies' tour of Paris, and a dinner for the four at a restaurant in the Eiffel Tower.
