One hundred years ago European civilization, as it had been known, was ending its life in the Great War, later renamed World War I. Millions of soldiers ordered by mindless generals into the hostile arms of barbed wire and machine gun fire had left the armies stalemated in trenches. A reasonable peace could have been reached, but US President Woodrow Wilson kept the carnage going by sending fresh American soldiers to try to turn the tide against Germany in favor of the English and French.
The fresh Amerian machine gun and barbed wire fodder weakened the German position, and an armistance was agreed. The Germans were promised no territorial losses and no reparations if they laid down their arms, which they did only to be betrayed at Versailles. The injustice and stupidity of the Versailles Treaty produced the German hyperinflation, the collapse of the Weimar Republic, and the rise of Hitler.
