“While many Rabbonim felt that Daas Torah was to stay in Europe, it could have been based on the fact that they misunderstood how powerful Hitler and the Nazis were.”
Ze’ev Jabotinsky and Arnold Schoenberg both predicted the shoah in writing in 1938, and they expressed the need for every Jew to get out of Europe ASAP. They clearly had better Daas even though Jabotinsky claimed to be an atheist and Schoenberg was a recent baal tshuvah from 35 years of living as a Christian.
