When did they first call WW2 by the name we know it as today? Like the Great War probably wasn't called the great war at the time when did they decide that the war with the Axis forces was substantial enough to call it a World War? Long after or what? I only ask as I wonder whether my kiddies, kiddies may one day be studying about the Middle East in their studies about World War Three? Food For thought or a simple answer?
