One of the best examples of how “WE” have changed since the immediate post war years I have ever seen was a bowling shirt.
It was made from a big Nazi state service flag. A large eagle holding a swastika from shoulder to shoulder, so large it’s wing tips were cut off by the sleeves. I am sure that the serviceman who had it made was proud to wear it out bowling just after the war.
How would he be treated now if he did the same.
Ancient Greek and Roman coins have images of helmets, armor and whepons from the defeated on them.
