At Arlington National Cemetery on Sunday, President Obama expressed the nation's gratitude to its veterans.
"Whenever America has come under attack, you've risen to her defense," he said. "Whenever our freedoms have come under assault, you've responded with resolve. Time and again, at home and abroad, you and your families have sacrificed to protect that powerful promise that all of us hold so dear –- life, liberty and the pursuit of happiness."
Veterans Day — originally Armistice Day — was renamed in 1954 to include veterans who had fought in all wars. But the day of remembrance has its roots in World War I — Nov. 11, 1918 was the day the guns fell silent at the end of the Great War. On this Veterans Day, we celebrate the poetry of World War I, one of the legacies of that conflict.
