YB:
The Steipler is misquoted as claiming that the “State” is halachically permitted once it’s been established. That is sheker gamur, as pointed out. He allowed only voting in that “State”, which would have no bearing on the continued anti-Torah existence of that “State” which he obviously never permitted.
And, again, the chashmonaim�s reign – about which you asked in your prior post – was during the time of the Second Temple, to which obviously the oaths did not apply. Same with the Chanukah and the Greeks. The oaths did not apply during the Temple periods. They came into force upon Hashem sending us into Galus.
Regarding the Khazars, the king converted after having already been king, and that kingdom anyways didn’t last, not that it matters since he didn’t ask any rabbi for permission to rule as a Jew; he just did so.
Bottom line: Zionism, of any flavor, is absolutely against G-d and His Torah.
