Ujm, what you wrote about Rabbi Hutner zt”l is copy and paste from somewhere? What is the source? You did not bring me a source where it says that he says what you claim he did. Furthermore, I’m not an expert on Rabbi Hutner’s biography, but he was a talmud of Rabbi Kook zt”l who mentored him for years and I can’t believe that he was so anti-Zionist if his mentor was Rav Kook.
What you write Rabbi Avigdor Miller zt”l said about Zionist leaders I can’t confirm nor deny. However, I see nothing that you wrote where he blamed the Zionist movement on the Holocaust, rather he blamed the atheist Zionist leaders for failing to do more to save Jews from the Holocauset. Thats quite different than blaming the Holocaust on Zionism as a movement. (Same as what you claim Rabbi Hutner said) One thing I can tell you as a fact I that I listened to many of Rabbi Miller’s tapes and on one tape someone asked what he says about the State of Israel. He said he cannot comment on that. The questioner repeated his question but Rabbi Miller said he cannot again that answer on that.
Here’s an audio on what he answered on the topic of voting in the Israeli elections which is a similar to what I heard that he is not poskening on the issue of the state of Israel, he is leaving it to other gedolim.
