“How dare anyone blame gedolim for outrageous Zionist treachery?”
The Zionists had their own gedolim.
And blaming Zionists for the Nazis is like blaming Israel for Hamas and Hezbollah.
“lobbying governments to not allow in Jews”
I challenge you to find a single Zionist, religious or not, who supported the racist immigration quota law in the US — a law that had been enacted back in 1924.
“The pattern that always held true in galus was that if one place became dangerous then another would open up.”
Actually there WERE places that some Jews could have fled to had the money been available and the gedolim given the word to flee: The racist dictator Trujillo decided that more Jews meant more white folks in the Dominican Republic, and he offered to accept tens of thousands of Jewish refugees. (He was probably trying to atone for his own massacre of tens of thousands of Haitians.) And after a year’s residence in the Dominican Republic, it was possible to immigrate to the US.
Haiti also was selling visas to Haiti to any Jew who could come up with $5,000 and again after one year immigration to the US was possible. A few Jews (under a hundred) took them up on that offer, but I do know one rabbi whose grandfather went through Haiti on the way to the US.
