And it is simply delusional to claim “He also clearly showed us an absolute early sign of the coming Geulah BB”A”. You have no neviim or even any gedolim to claim that and, of course, the gedolim have said just the opposite.
Even the letter which Zionists still tout as if it were some psak din, rather than a slimy forgery, never originally said those words, never mind who did or didn’t even sign the letter in any form.
Regardless, Zionism and its victories in 1948 had nothing to do with the geulah. Simply, a Mitzva haBaa baAveira is not a Mitzva and the founding of the State entailed various severe aveiros. Founding the State was absolutely assur in many ways, and to say Hallel for such a thing is patently absurd.
Of course MO/”Religious Zionism” has been making it all up and just as certainly they do delude themselves into thinking that there might be parameters for their inventions (which even Sam2 admits are not muchrach, even liShitasam). The problem is that the gedolim very much did and continue to disagree with MO/”Religious Zionism” at least as much as they did regarding any other deviant movement.
Even the “left-wing” Rabbis admit that MO/”Religious Zionism” changed (their) Judaism.
Like Eliyahu Fink, for instance, who blogged what any high school student could tell you after learning about European Nationalism, and then reading Orot (which, incidentally, the Chazon Ish, among others, also forbade): that Rabbi Kook merely took Nationalism and grafted it onto, liHavdil, our holy Torah. (Rabbi Dr. Lichtenstein also wrote similarly, though he obviously concluded positively, regardless.)
The bottom line is that Rav Elchonon and others said that Zionism is Avoda Zara and “Religious Zionism” is simply religion mixed with Avoda Zara. The whole MO/”Religious Zionism” is simply a non-starter.
