The same people who by shitta do not vote in Zionist elections (and they are halachicly required to continue practicing and upholding that shitta as per the psak of their rabbonim) also will refuse to enlist in the Zionist army and refuse to teach their children Israeli core education requirements.
Even if the Zionist pass a law requiring it. Does anyone imagine it won’t be ignored and disregarded? I think everyone knows, especially the secular Zionist and lawmakers, that it’ll be ignored.
