So many? Stop kidding us, mdd. Chareidim who take an exemption are a small portion of the national total of draft-eligible Israelis. Is the Israeli Army currently falling apart due to a lack of Chareidi inductees? Is the Israeli Army losing wars due to a lack of Chareidi fighters? Nope and nope. They are doing just fine without us. The only reason for the current noise by the chilonim is due to their rabid Torah-hating anger and hatred of anyone with a yarmulka.
Where is the demand that Arab Israeli citizens serve in the Army? Where?
