HaKatan,
Are you defining anyone who was pro-Zionist (religious) as automatically not a Gadol?
I assume you have heard of Rav Avraham Yitzchak HaKohen Kook and his son Rav Tzvi Yehudah HaKohen. You probably have also heard of Reb Shlomo Yosef Zevin, Rav Yitzchak Herzog, Rav Yissochor Shlomo Teichtal, The Nazir of Yerushalayim, Rav Yitzchak Arieli, and Rav Yosef Dov Soleveitchik. Zichron Tzaddikim L’Vrocho.
