Charlie – The mesech chochmah by R’ Meir simcha writes in the 1920s that one day germany will be a “shulchan aruch” of slaugther for the Jews, and that those who called Berlin their Jerusalem shall see the true germans…
But it is true, prewar jewry was not warned by Gedoley Yisrael to leave Europe. Had they known with clarity, surely they would have sounded the alarm bells. R’ Yoshe Berr uses this to prove that the Holocaust was a divine event; that the leading Torah masters were divinely blinded to it’s coming. We find a similar concept by the Churban.
