avhaben- I disagree with some of your points.
1. If that’s the attitude, then government funding shouldn’t be taken either. That’s like taking goods from a store but because you oppose its existence then you refuse to pay for it. If you are benefiting from the State, then you also have to pay for it whatever they charge, be it taxes and/or service. If you oppose its existence to the point that you won’t follow its rules, then you can’t take the benefits either.
2a. A desire is not enough. You also have to be willing to put in the time an effort. Many guys genuinely want to sit in Kollel, but they waste time when they shouldn’t be… either by missing sedorim or not learning as hard as they can when they are in seder. The people who should be in kollel are not necessarily the strongest learners, but those who want to be there and are willing to put in as much effort in their learning as they can for all the required amount of time.
2b. There is a concept of “yagata umatzata ta’amin, yagata velo matzata al ta’amin.” Basically translated as if a person says they put in effort (in Torah) and were successful then you should believe them, but if they say they put in effort but didn’t succeed then don’t believe them (that they put in effort). There is a havtachah that a person who puts in effort in learning will be successful (though I admit, I do not know how to define success). While it is true that even a poor learner has the right to sit in Kollel, if he doesn’t succeed in his learning, it implies that he is not trying so hard.
3. I don’t know the metzius, but assuming the medinah will expand Nachal Charedi (which I don’t know if they plan on doing that), then it should be fine. And even if it doesn’t, the army lichorah is no more pritzusdik than your average job in Israel or America. Yeshiva should prepare Benei Torah to be able to work in the real world and to overcome these challenges. If the army will turn frum draftees into chilonim, then our parents and yeshivos have failed us. Are you saying that no frum person should be allowed to work because the secular world is inherently a pritzusdik environment?
4. Even in the times of Moshe and Yeshoshua they had armies. The soldiers were the talmidei chachamim. Hashem told Gidon specifically to take the best people for the army. Learning Torah is the true protection, but not to the exclusion of derech hateva. In fact, it’s probably even better protection if the Talmidei Chachamim bring their zechusim to the battle field.
5. I don’t know if that’s true. If the government wants them to serve then that implies they need them. Maybe I’m wrong. I guess I’m still naive and believe that the secular government is not “anti-frum” they’re just not frum and I don’t believe that the government of Israel is trying to get rid of the Chareidim and Kollel.
