Why is it that Yeshiva boys are not serving the army in Israel?

Dear Rabbi
Why is it that Yeshiva boys are not serving the army in Israel? I never read in the Bible or in any other books that it is against our religion. Students in the University have to serve every summer holiday three months, and after they finish the university they have to serve the rest of the time.

Dear Nathan
That is something of a generalisation. There are certain Yeshivot the boys learn part time and do their military duties part time. Interestingly enough, in Biblical times, every male over the age of 20 had compulsory military duty. Of course there were exceptions but that was the standard rule. There are two things to take into account: the first is how the Israeli army today is mixed and that presents a problem for many young Orthodox men. However the army got around this problem by allowing for the separate troops when so required. The other point is that inasmuch as the military serves to protect us physically, the Torah serves to protect us spiritually. Even as we may have foot soldiers we also need soul soldiers. While the rest of us are caught up in the daily grind, the world is being infused with spiritual oxygen through the power of those who study.
Many Yeshiva boys are raised in a certain mould and a whole new-fangled experience as that which the military provides can be very counter-intuitive to their whole stability. In short, they simply wouldn’t be able to handle it. It’ll throw their religious stability off kilter.
Having said that, again, the Israeli military today provides for Rabbis to be with their troops and offers more by way of dealing with this problem as well. Therefore, inasmuch as you and I cannot see that sweet Charedi boy Bnei Brak in military fatigue running through the trenches, there are many others who can, and dare I suggest, should get more involved. The army is there to protect the people and everyone, to one degree or another, shares in that mutual responsibility.
