It was called "The war to end all wars," but World War I ushered in revolutions, tyrannical regimes, and an even bloodier global conflict two decades later. The Associated Press marks 100 years since the signing of the armistice.

PARIS (AP) — For President Donald Trump in Paris, America First meant largely America alone. At a weekend commemoration of the 100th anniversary of the end of World War 1, the president who proudly declares himself a "nationalist" stood apart, even on a continent where his brand of populism is on the rise. He began his visit with a tweet slamming the French president's call for a European defense force, arrived at events alone and spent much of his trip out of sight in the American ambassadors' residence in central Paris. On Sunday, he listened as he was lectured on the dangers of nationalist isolation, and then he headed home as the inaugural Paris Peace Summit was getting under way.
