The racial classification boards that were established by the 1935 Nuremberg Laws considered a person with two Jewish grandparents a "Mischling" or a person of mixed race (known as a first degree Mischling). A person with only one Jewish grandparent was a second-degree Mischling. There were perhaps 150,000 of these people of "mixed race" who fought in the Nazi army.
There weren't "many" of them (taking into account the total numbers involved), and they were not considered Jews. They were considered people of "mixed race," which is what Mischling means. The facts won't prevent an idiot like Cosby from trying to make it appear otherwise, however.
So although there were many (150,000 definitely qualifies as many) partial-Jews fighting in the Nazi Army there were very few "pure" jews fighting with them.
source says ~20 million nazi soldiers so ~150,000 partial-jews would be less than 1% of nazi soldiers Thanks for the info.
If their maternal grandmother was Jewish, then they would be Jewish, irrespective of the ethnicity or religious orientation of the other three grandparents.
What does Rita Cosby have to do with anything? NBC was the first to run it. The book has been reviewed in several maor newspapers.
No big surprise there were people of all groups on all sides in WWII. Jews played as large a role in the creation of fascist theory as did Christians. Mussolini's top advisors were Jewish as was the editor of his fascist newspaper. A lot of people of all faiths did not have a clue where this ideology was headed.
