The event, which included a joint fly-past of fighter jets from two countries as a symbol of military cooperation in the Middle East and other regions, followed a day of discussions with French President Emmanuel Macron, a tour of Paris for the first ladies, and a dinner for the four at a restaurant in the Eiffel Tower. Trump tweeted about the great evening and the strong relationship with France. Macron's visit was seen as a way to enhance France's global reputation, and potentially help the US leader who has faced criticism for his views on free trade and climate change. Trump, who is also facing an investigation into alleged Russian interference in the 2016 US election, hinted at the possibility of further discussions on the Paris accord, from which he withdrew the United States earlier this year. Macron arrived in a military jeep surrounded by cavalry, reenacting a scene from his inauguration and emphasizing his country's military strength. The parade also brought attention to a recent dispute between Macron and General Pierre de Villers over defense budget cuts. During the event, Trump and Macron sat together, applauding and pointing as military aircraft flew overhead. Trump saluted as military personnel, some wearing World War One uniforms, marched past with the Arc de Triomphe in the background. This year's Bastille Day holds special significance for France, as it marks the first anniversary of one of the most deadly Islamist militant attacks in recent years. Following the parade, President Macron will travel to Nice to participate in a ceremony honoring the 86 individuals who lost their lives in a tragic event where a Tunisian man drove a truck into a crowd on the waterfront one year ago.
