In the movie The Best Years of Our Lives there is a scene where a fight breaks out between a returned WW2 GI and a customer in a drug store who tells him he wasted his time fighting in the war.
There have always been a bunch that conclude any war is a mistake.....
Even when there is such clarity as in WW!!
The Customer in that Movie thought the War was a mistake after it had ended and we had Won.
I wonder how many Germans and Japanese thought the War was Justified even after they had Lost?
I’ll bet there were plenty of both. Food for thought.
