OddAnon: Which Roshei yeshivos? Based on past experiences in Israel, it will consists of those with the closest ties to the ruling class (this is politically important because if the Sefardim feel insulted, even pro-zionist Sefardim will continue to support Shas).
How they will deal with anti-zionists isn’t clear since the zionists didn’t realize they exist, and are only now beginning to realize that much of the hareidi community never bought into the zionist narrative about Jews having a right to rule Eretz Yisrael, or of the Arabs being a mortal threat to Jewish people (rather than former friends and potential friends annoyed at being chased off their land). When the anti-zionists refuse to do paperwork, will the Israelis start rounding them up? Will they be included in the 1800 exempt from Chappers?
Already the left-wing parties (both the zionists of Labor and Meretz), as well as the three non-zionists, predominantly Arab parties, have realized that they may have a new ally that could radically change the Israeli picture by making a “left” government possible (after 30+ years in which the right/center controlled the government). I suspect that fear of this happening will encourage the nationalist zionists to find a way to exempt many hareidim, even if it means allowing for any Israeli to be a “conscientious or religious” objector to military service, and that will transform the “1800” is a cap on the number of yeshiva students offered state subsidies. Bayit Yehudi and Likud Beiteinu may hate Torah, but they hate losing power even more, and the possibility of a Labor led coalition including Hareidim and Arabs will force them to back down.
