Wasn't that an important factor that led to WWII? Everyone but Adolf Hitler had had enough from the last war. Turkey was just blessed with being an insignificant enough player that they could get away with opting out. The people of England and France were reluctant enough to let the Germans steal a march and loose the catastrophe we are now following.
I think the godawfulness of WWI was the primary factor that lead the French to capitulate to Hitler rather than fight on from their colonies.
