completely disagree
the reason no one has really “won” a war since in WW2 is that the rules of war would specifically created to prevent someone from winning.
In my opinion the rules of war exist only to make wars unwinable and unprofitable and thus freeze in place the current status quo.
I think I agree with what you are saying. WWII established a lot of “rules” and established a post-WWII world order which did provide stability and 80+ years of peace (no really big wars, anyway).
That’s not all bad.
But my personal opinion is that time moves on, the world changes, and the rules and the world order may not be worth keeping forever. I think there is something to be said for truly winning some wars, and if that idea comes back, the casualties would be in the millions. We currently have the idea that such a war is “unthinkable”. I think the time approaches when we will have to think about it.
Believe me, these rules of war make continual wars very profitable.
