Participant (and we all are), I think I responded to someone else. I see a problem with your argument that you talk like a consumer: those in power owe you a justification for you to agree to something. Think like a free religious person about your obligation to Hashem and other Yidden. Someone (a person or a community) who lives together with others needs to participate in the society. If you think Army is not doing something right, vote and raise your own officers and push your policies. Sometimes, in a democracy, you have to even accept a decision that you think is wrong.
“Yeshiva as a Maimonidean desert” that Chazon Ish created is not a correct analogy. Living in a desert presumes you take care of yourself, not erquesting others to send an army to protect your oasis.
