ZSK:
TiDE is distinctly different from MO TuMA. For one, TiDE has austritt, as Rav Schwab has pointed out. More importantly, it does not elevate anything else as having intrinsic value, unlike the idolatry of TuMA.
Idolatrous Zionism has been a part of MO’s (idolatrous) identity since its founder started it. He was the head of Mizrachi, as you know, and has published idolatrous nonsense about Zionism including his “Kol dodi dofek”, which any card-carrying “Religious Zionist” would hold of. No, MO Zionism is not just saying some prayers (which are themselves problematic/heretical, in some cases, as it happens) and sending their kids to learn in Israel. You certainly know better than that, as do others, incidentally.
Your contention about RZ being just about working with what’s there is so absurd that surely even you don’t really believe that. The “Religious” Zionists are generally the most fanatical Zionists of all, much more so than the “Secular” ones. Either way, Rav Elchonon and all the others (including the Brisker Rav who lived in then-Palestine and then also post-State as well,) noted that “Religious Zionism” is idolatry and heresy.
Zionism has two basic assertions that all Zionists believe.
1. The heresy that Jews are a nation like all others, with a common land, language, and culture, as opposed to being a Torah-based people which is the truth.
2. That the “State” of “Israel” is the Nation-State of that mythical Nation.
