"The Great War - I was referring to a little disagreement that took place between 1914 and 1918 (for most countries involved) which certainly didn't have too much to do with religious differences, and with the consequences of which we are still living through today."

The war was still a part of the prevailing Christian righteousness of American leaders at the time. However the this war was not ostensibly a prevailing religious one. Still, under the pretext of morality and religion, Eugene Debs and Bertrand Russell were jailed under the sedition laws of the time. And the war impacted the "Easter Uprising" in Ireland which wanted Home Rule. We still live with the Christian ethic of war today which is unduly controlling the U.S. military now.
