Are you referring to the time of his adolescence, when George Soros at the tender age of fourteen was being groomed by the Nazis?
Then, grooming complete he turned fifteen, the war ended, the Nazis lost and Soros ran out the back door when nobody was looking.
Soros is evil, but not all those who are evil are Nazis. From what I know he helped his father who was working with the Nazis. His father was not a Nazi either.
