The IDF doesn’t want Chareidim and Chareidim don’t want the IDF. It is a mutually beneficial non-relationship.
The only agitators demanding change are the antisemites (some of whom even wear a kippa) who hate Chareidim and want to de-Chareidicize them by forcing them into the army melting pot to secularize them; much like 50% of the daati leumis who join the IDF by time they are discharged are no longer religious.
