Vayoel Moshe -Satmear Rebba
The Seforim Hakodoshim talk of the Tikun you have going to Galus, without jews in golus all jews would die (see roman story in Pesachim,jew in 4 corners). Golus makes gerim according to Mahrsha increases emuna.Its in all the midrashim UNTIL MASHIACH COMES jews will be in exile (Moshiach is Divine given) for example it says ‘I will redeem one from Brittania or Barbaria’.
Ramban wasn’t talking about all jews going to Isreal, his mitzvo doarrasiaa aspect was for the the person mentioned by Rabbenu Chaim ‘as we are not Zariz to fuffil the Mitzvos of isreal and the danger of roads there is no Mitzva nowadays of living in isreal.–THAT PERSON WHO IS ABLE TO DO THAT.
Quoting Teshuvos, he writes that generations have fallen drastically. Going to Israel with a Zionist manority you have a worse aveiro then those Minim who do the sins you assist them (unless you go to Brisk in Isreal). You have a chiyiv to protest, but not in isreal the Zionists influence the Tzivonim (orthodox) and make them into them (this was written in 63′ see the frum in now there detoriated).
Sharrei tzedek quotes a law in Jerusalem in his time a unmarried man from 20 to 60 could not come in the city. Even Ramban was discussing people who come to isreal to live most keep the whole Torah. Sefer Charedim and Sla Hakodesh emphasize this.
Avnei Nezer mentions you move yourself from mitzvos(see Talmud Menochos, where heavenly angle accuse when no garment is worn, so exempting Tzittsit), is disagreed by the poskim and rishonim. Beis Shlomo holds torah study dochas yishuv isreal. This would also apply to Mitzva (Dochas a Mitzva).
Maharit who quotes Moderchai is disproven that Tosfas Rabbeinu Chaim erred, by Maharat.
Bach, Shach, Mahasha, Mahashal allow cohenim to leave chutz laeretz as Tumah is prevalent even in isreal. Supporting torah and mitzva people in isreal is a neccesity to support minim is the opposite in Isreal. The Yetzer Hara is magnified in Ikva de Meshicha, what used to be a Mitzva is now a seen as a aveiro, to throw off the yoke of Mitzvos for Yishuv Eretz Yisroel. Mahabit, Rham all support Sla and Sefer Charedim. —-ITS CLEAR FROM ALL RISHOINM PEOPLE WHO ARENT TZADDIKIM (kEMAT GIMMURIM) ARENT WANTED IN ISREAL BY G-d– The zionist change minhagim making askenazim speak sephard nusach and duchan every day–KEFIRA
I saw the second teshuva which says Ivrit should not be taught at all –its Osur to change torah, speak it unnecessarily especially for Bitul purposes, e.g. in 2nd temple era they spoke aramaic and greek, WOMEN especially shouldn’t be taught Ivrit as its forbibden to teach them Torah that isnt relevant to them–girls in Zionist chinuch atzmai schools are forbidden to read external books.
