“Let’s take it as a given that learning Torah adds to our protection and is a component of our military defense. Personally, I believe this. It’s part of our Mesorah. The big problem is that it’s a very vague statements and WE DO NOT KNOW HOW IT WORKS.”
So what? We don’t need to know “how” it works; we know it works. That’s enough.
“what’s the ratio of learners to soldiers?”
Currently there are far far too few learners. We need to increase, greatly, the number of learners.
“there is no critical, detailed, analysis of how it works and what we need”
The Gedolei Yisroel shlita have already long made this analysis. There’s no one more qualified than Gedolei Yisroel shlita to make this analysis. The Gedolei Yisroel shlita are easily reachable. They do not live in Ivory Towers. They do not have security details. The Shin Bet does not keep people away from them. You can easily approach them and respectfully ask them. They will answer you. No need for coffee room threads.
