Paris, November 12 (RHC)-- In Paris, U.S. President Donald Trump joined world leaders Sunday as they gathered to pay tribute to the millions who died in World War I on the 100th anniversary of the armistice that ended the war. 

Speaking at a formal ceremony at the Arc de Triomphe, French President Emmanuel Macron warned that growing nationalism in countries including the United States threatens the world once again. 
 
After the ceremony, over 70 heads of state attended the Paris Peace Forum. President Trump was the only head of state present to skip it, returning to the U.S. shortly after it began.  Trump also faced widespread criticism for his decision to cancel a visit to a U.S. military cemetery on Saturday because it was raining.
