“Who with big enough shoes has said that we now change Jewish practice from throughout the ages as a result of the Holocaust?”
I dont follow. Different circumstances call for different approaches. Yaakov avinu taught us how to face enemies with three different approaches. All are appropriate depending on the circumstance.
“but you think a couple hundred Jews with guns can beat the German war machine? ”
No, and I explicitly sad so. The point wasn’t to beat the German was machine.
“(even putting aside the reality that some likely would have survived),”
Maybe more survived as a result of the uprising, thats only for the Boreei Olam to know. After all some did escape, the uprising DELAYED many people’s deaths as it took the Germans about 2 months to empty the Ghetto. when the decision to empty the Lodz Ghetto in august 44′ was made it was emptied in less than a month and most were gassed upon their arrival to Chelmno. Perhaps if they too had revolted they would have delayed the ghetto’s destruction.
“Who have a couple hundred people the right to engage”
The Ribono shel Olam as reported by his emissaries in the Ghetto, the Rabbonim at the time, and as outlined by our history eis milchomo veis shalom, sometimes bargaining is appropriate sometimes fighting is appropriate.
