His generation was America's other "Greatest Generation". All of them honestly believed that war would end all wars because it was so terrible.
You can go to France and Luxembourg and still see very carefully tended cemeteries from that war.
Remember Mr. Buckles when November the eleventh rolls around again. Their war ended at 11:00am, on the eleventh day of the eleventh month. It was always "Armistice Day" to those magnificent old men.
I'm also sure that Mr. Buckles' family misses him as much as I miss another veteran of WWI; My father who served in the Field Artillery and was in France when the war ended.
