The greatest Torah sages of the past century and beyond have blasted Zionism for the idolatry and heresy that it proudly is.
Rabbi Teichtal’s book was written during very desperate times and his introduction in any event states not to rely on it as a support for any -ism.
We’ve gone over this way too many times: the State is idolatry and heresy and a colossal chilul Hashem, not to mention communist-textbook-case propaganda and identity theft of the Jewish nation.
The gedolim were and are quite clear about the cataclysmic disaster for the Jewish people that was Zionism.
The Rambam who the MO love so much brought down the oaths in Iggeres Teiman. The Satmar Rav answers all the nonsense that Zionists try to bring up in a desperate attempt to hold on to their idols. Might as well just give it up.
