What did Hitler threaten?

I'm almost positive it was to kill all of the Jewish families. I know Hitler only believed in people who had light colored skin, blond hair, and blue eyes and he thought other people didn't belong. The Nazi's I'm pretty sure were like his army so that they would go out and kill others who didn't look they way they thought they would look. It's weird because most Nazi's don't even look the way the Nazi's believe they are supposed to look!

He threatened the jews
