Eretz Yisrael (especially Kedushas Eretz Yisrael) has nothing to do with zionism. It is zionistic to think that it does!
This is where Joe fails. Just because there is a Medina, Mandate or PA doesn’t mean that the very air, soil and rocks of our land do not belong to us. Hashem gave this land to us no matter who “controls” it. We are commanded to treat it differently than other lands. It is more Kadosh by definition than any other land in the universe.
I’m bothered by the same concerns as the OP.
