Ok. Once this thread got somewhat distracted by the eternal Zionism debate:
Why is Zionism such a hot topic of debate? The State of Israel already exists, and there doesn’t seem like there is much we can do about that. (And I think that most Anti-Zionists don’t advocate for destroying the State.) It’s pretty obvious that the State does good things and bad things. On any given issue related to Israel, every posek/important Rabbi/whatever you want to call them should formulate an opinion in much the same way as they do in any other area. If the question is whether or not to serve in the army, then the issues to be determined are whether it is a milchemet mitzvah, whether it is pikuach nefesh (both physically and spiritually) in either direction, whether it is unacceptable bittul torah etc. Conceivably, one can hold that one is obligated to serve in the army on the basis of ????? ????? ??? ?? ??? ????? (Hilchos Melachim 5:1) yet still be an anti-zionist. Similarly, one can be a fervent zionist and still hold not to say Hallel on Yom Ha’atzmaut because that is his/her conclusion in the sugya of Hallel. The various positions on the contemporary mitzvah of living in Israel also should be irrelevant to Zionism. The only real difference that I see, is the extent of focus on Israel/the State of Israel, which hardly seems like something worthy of such devisiveness.
