“Nazi policy for women was confused”
I agree with this to a certain extent. In the beginning it was not confused, because a woman’s only role was to be a mother/homemaker. However in the late 1930’s it became more confused, because the Nazis needed women workers, because the men were fighting.

“Nazi policy for women was a failure”
It was sort of a failure. Towards the end, the Nazis could have used women in the factories or as nurses or something, but their biases about women prevented them from doing that. But it was not all a failure because the birth rate increased from fifteen per thousand in 1933, to twenty per thousand in 1939.
