Also the same answer can be given to "What was the turning point for the Jews?".

In 1935 Hitler created the Nuremberg Laws which was the turning point for Jews.

It isolated Jews from Germans the Laws included "No marriages are allowed between Jews and Aryans".

Kristallnacht - The night of the broken glass

SS smashed up Jewish shops - 91 Jews were killed - 20,000 taken to concentration camps.

No Germans protested about this.

In 1939 30,000 Jewish men and boys had been taken to concentration camps.

THE FINAL SOLUTION:

Concentration camps were enlarged and death camps were set up.

Jews, gypsies and many other groups were shot, gassed or worked to death.

6 million out of 8 million Jews were killed in the Holocaust.

This was kept a secret from Germans.

No Germans asked questions.
