The way not to need them for a sane and sound coalition is changing the byzantine, ultra-representative, ultra-democratic parlamentary system in Israel. The way to change that is for a unity government that mixes secular right, with center and left, -despite their mutual loathing- and gather 61 Knesset Members. Then, all forces must be gathered to change the electoral system. Once it has passed the Kafkian stages and becomes law, segregated education within the Ultra-orthodox communities must include civic studies instructed by non-Haredi teachers, combined with religious teachings on Israeli values. The way to do that is an educational revolution whereby ther ultra-orthodox can't live ina wholly parallel universe any longer. And that, yes, requires a constitution that is enforced. They must come to terms with the values of Israel, just like the rest of the Israeli society. Minority rights, yes. Minority blackmail and violence, no.
