HaKatan,
1. What about Rav Kook, Rav Shlomo Zalman Auerbach, Rav Mordechai Eliahu, Rav Zevin, Rav Soloveichik, etc,,etc.?
2. Rav Ovadia said that if not for the IDF, there would be no yeshivot (see See Sanhedrin 49a). The IDF s now facing a severe manpower shortage. We cannot afford to exempt more than a very small elite, who can be a branch of the IDF Rabbinate. The rest can be in various types of Chareidi units. Military intelligence is especially suited for those with Gemara heads (there already exists such a unit ) and is also a pathway to good jobs.
3. What do your gedolim say about Internet usage? Just curious.
