rationalfrummie,
That wasn’t the scenario you set up. You set up a scenario whereby the State of Israel would have been established already in 1933 and all of the 6 million (not just frum Jews) would have been living in Israel.
In that scenario, Hitler, commanding one of the most powerful armies ever and having a desire to kill off the Jewish people, would most likely have launched an attack on the fledgling Jewish states and destroyed it and all the Jews within it.
Agav, in the 30s, when things in Germany started getting bad, it was extremely difficult to get into E”Y. The Jews were severely limited in the number of Jews they could bring in and the frum Jews were limited to an even greater degree. A different attitude by the Rebbes of Europe might have save hundreds or thousands of lives, but it would not have saved the vast bulk of European Jewry.
