Regarding your “yes or no” questions, I already mentioned the Chazal about the Romans and the bathhouses they built and Hashem’s answer to their claim for reward.
Please answer yes or no if you feel that Hashem is, CH”V, kafui tov, for rejecting the Roman’s claim. (Of course, Hashem will have rewarded them in some other way because He doesn’t hold back reward from anyone.)
Once you’ve done that, please explain why Israel and the IDF should be any better.
