Sorry to bust another bubble, but it was precisely the opposite. It were the Rebbes and the Rabbonim, who by and large discouraged or have outright forbidden leaving Europe, especially to the USA. Whether their reasons were good, or even absolutely correct, there is no point of lying and changing history, laying the blame on the Zionists. Even if the only aim of the latter was to make everyone irreligious and turn them into total reshaim, it were not the Zionists who chose to keep the Jews in Europe.
EDITED
Interestingly, whatever plans FDR may have had in 1948 remained with him in the netherworld. One does not need to dig into old letters and documents to avoid such glaring mistakes.
Also, do tell why the great Rebbes themselves ran from Hitler with forged papers and shaved faces, or hid in Polish barns. Were they not following their own advice to stay in Europe, or did the Zionists cause their demise?
