Precisely.
Brunner was born 1912. If alive today he would be 102 years old. Highly unlikely.
It is fair to say there are no major Nazi war criminals alive today.
Yes you can still find some low level ageing camp guards around, but war crimes trials were originally established to punish the higher ups, high ranking officers and party leaders, high ranking government officials and policy makers. Not low level camp guards.
If this is the new standard for war criminals, I’m sure we could find many thousands of them from the former Soviet Union and among the Chicoms who annihilated many millions more than Nazi Germany.
What was the Ayn Rand quote? “When you run out of criminals, make more criminals”?
Who are the next criminals?
