The really indisputable war criminals (on the losing side) are either dead, in prison, or were protected from prosecution by various governments so they can’t be touched. So, there is nothing left but these “small fry” to go after, and almost all of them can say they were forced into doing what they did. I wouldn’t doubt that a great many of them really were. However, they are the only ones left, so that is who the Nazi hunters are going to hunt.
Nobody wants to even risk being seen as sympathetic to a potential Nazi, so nobody is going to go out of their way to put a stop to the pointless exercise. I suppose it will continue until everyone from that era passes away, which should be pretty soon.
“Nobody wants to even risk being seen as sympathetic to a potential Nazi”
Except if they’re izlamic.
