You seem to be conflating Zionism with, liHavdil, Chovivei Tzion, about which, incidentally, Rav SR Hirch and others were very against, and about which its founder ultimately expressed his regret.
It’s simply impossible for any “Orthodox” Jew to be a proponent of what I wrote above – replacing Judaism with, liHavdil, an almost pagan land-based nationalist idol with some “Jewish” themes, etc.
Rabbi Soloveitchik proposed ideas (like Modern Orthodoxy and “Religious” Zionism) which were condemned by gedolim. So you can’t bring him as a support for Zionism. But even if you would bring him as a support, his students espouse positions about Zionism with which even he explicitly disagreed, and his stated reasons for supporting both “Modernity” and Zionism have been shown to be either irrelevant and/or wrong – certainly nowadays.
The Modern Orthodox “foolishness bordering on heresy” to quote Rav Schwab) has long been recognized as the silliness that it is, and the Zionist ideology and State/idol have long been exposed for the brazen heretical and idolatrous identity theft of Judaism that they are. Unfortunately, many are still taught this same “fossilized” (again, quote from Rav Schwab) nonsense with which no gadol even agreed.
