By the time the Nuremberg laws (especially the Reich Citizenship law) were promulgated in 1935, German Jews knew they were no longer protected by law, and it was obvious to Jews everywhere that German Jews, as non-citizens, had none of the protections of German citizens.
Or perhaps hoped that something would be done to stop it.
The problem is also to do with the hierarchies within many of the Jewish communities in Europe.
Read something along the lines of Hannah Arendt's "Eichmann in Jerusalem" and you'll come away pretty nauseated at how much, even 45 years ago, had been discovered about how, in some cases, our elders sold us out, how in others they "ratted" on anyone who might resist, even how, in some cases, they handed over birth records that helped the Nazis trace other Jews.
There was also, as Rachamim agreed, a streak of fatalism in some of the eastern European Hasidim that literally led to them going to their deaths without complaint, because it was HIS will.
