Sadly the Satmar reba zya was wrong during the war too. Many zionists saved jews and had the jews ran or cooprated with them perhaps more would have been saved. I know Satmar spreads this myth that Kastner was shlecht and the frum ones weren’t to blame. Leaving aside how the reba was saved, Katstners goals were always to save all Hungarian jews till they couldn’t. It was the frum rrosh Hkhal of Budapest that lied and fooled his people telling them to cooperate with Nazis.. The reba then went on to bully anyone who was pro zionist. Henceforth, the holy Kluasneberger suffered his whole life from der feter Lavon and forced bobov to remain quiet about zionsim. he was a holy jew but was very strong on others who disputed him. Henceforth, people were afraid to respond to his sefer al hgeulah val atemurah or they’d be ois kaplitch macher. (I know someone who refuted it and had all his sefarim burned)
Don’t forget the many holy jews who celeberated Yom hatzmut. All the Rizyna rebas were open zionsits some even mizrachi. (The shtefenst who was the ribntzer and skulener rebas, rebbe had a picture of Herzel and was an outward Zionist) Punvitch still raises their flags and the first year the Mir had one too. Rabbi Herzel the cheif rabbi, went on dangerous missions to save jewish children in monasteries after the war. he used toc ry for jewish neshomas. He also did so much during the war.
Eevn zionsits in the past weren’t straight bad .Your comment re Israel today is certainly spot on.
