President Donald Trump saluted American service members marching in France’s Bastille Day Parade, marking the European nation’s national holiday and commemorating the 100th anniversary of the United States entry in to the first World War.

President Trump -who was invited as an official guest of honor- viewed the parade alongside First Lady Melania, French President Emmanuel Macron, and his wife Brigitte.

Macron transformed the parade into a celebration of not only the beginning of the French revolution, but also the unique bond between the two nations; incorporating American flags, American soldiers, and the Star-Spangled Banner into the festivities.

As American service members marched down the Champs-Elysees, President Trump rose to his feet and saluted the men and women of the US armed forces.

Later that day, Macron addressed the French people and expressed his gratitude to the United States for its involvement in the first World War, noting that the bond between the two nations can never be broken.

“And that is why I wish to thank them, thank the United States for the choice it made 100 years ago,” said the French leader. “This is why nothing will ever separate us.”
