“the question of the continued EXISTENCE of the state is intertwined with the pikuach nefesh of millions”
Not really. That is literally textbook Zionism, and is heretical because it takes power away from G-d and transfers that to the “State”. Again, that “State” is a gross violation of not only the oaths but kol haTorah kulah, as the Brisker Rav noted. Obviously, as the Chazon Ish noted, it is simply a matter of time until Hashem ends that nightmare idol and its “State”.
Therefore, the core question of the continued existence of that “State” is in no way an actual pikuach nefesh question.
Obviously, if its dismantlement/transfer of powers were done improperly, then it could be a tremendous concern of pikuach nefesh, if that’s what you meant.
But regarding the core question of the “State” existing, there is obviously zero pikuach nefesh concern. If anyone claims otherwise then they are simply foolish and/or Zionist heretics. The Brisker Rav stated that it will not be the Zionists from whom Mashiach takes control of the holy land. So, obviously, Hashem will arrange the downfall of that Zionist idol, too, like all other idols, and He certainly will address any pikuach nefesh concerns.
