Answer: First, the Jews didn’t believe that the attitude toward them could become so negative, and that is what they believe even today when they are on the threshold of another Holocaust.
Second, the spiritual leaders convinced them that everything would be okay, that it was up to them to wait for the Messiah where they were. So, three million faithful Orthodox Jews, Poles who heard the voice of their leaders, met their death in the gas chambers.
It must be pointed out that the Kabbalists warned them before the Holocaust and tried to convince them to leave Europe, but in response they received only curses. The Kabbalists managed to escape in time.
