Where was no WWI, WWII, etc. It's all been the same war and it has not ended. The combatants have always been the same. Country names have changed. Names of the leaders (but not their bloodlines) have changed. Names of the enemy have change (but not the ideologies). Theaters of conflict have shifted around the globe but it's always been the same fight.
It's been a 100 year war for this era. 11/11/18 will mark the end of that war apparently.
