It’s the ‘vengeance’ part which spoils the whole thing.

Evil is to be resisted, of course, only this is better done in a sustainable manner.

WWI was won for nothing. The vengeance part in the Versailles ‘peace process’ had spoiled the whole thing.
Hence the war had to be won again.
During the process, the winners had become wiser. Some of them, at least.
The peace process had been inclusive this time.
The North Atlantic region, the end result of that peace process – no scare marks needed this time, is one the most successful stories of human development.
