Why were the Jewish youth so vulnerable?
Because they couldn't fight for them selves so when the Nazis came to take them they could fight to get away. they also didn't have the money to travel somewhere safe or to go somewhere and hide.
The Nazis moved the Jews into concentration camps in little box cars and at some point they got over 200 Jews onto one box car
in the end hitler had killed over thousands of Jews and some people to this day have denied that the holocaust had ever happened but i think Jew would say other wise
