That would work... but the Chareidim don't actually believe in their defenses (they flee places getting bombed and leave the soldiers to defend people's lives), nor are these defenses backed up in any way by halacha (they're misinterpreted that one text they use as a source). Also, they don't allow anyone in their community to go into the army. Ever. And they don't let non-Chareidim join them in their learning for defense, either.

What I wrote was a steelman of their positions, and must be taken as such. They themselves do not have such sophisticated mental models of the world. The answer to why they hate the IDF and the state of Israel is simply one of tribal affiliation. <>
[Edit: Also see point 3 in iarwain1's linked comment. It explains the hareidi attitude to all this.]
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
