All I can say for WWII is it is a good thing that Hitler was stupid enough to attack the Soviet Union and then turn around a few months later and declare war on the US two nations that had nearly unlimited manpower(and woman). Logistics the real war winner or loser if you lack it.

Also as you say no one nation alone "wins" a war of such scale.In fact no war is truly "won" one side usually achieves its goals or both sides tire and sue for peace.
