DY, please, please disabuse yourself of the notion that Kochi veOtzem Yodi is a common belief among soldiers in the IDF or among even resisters in the shoah. Even the completely frei Bielski brothers valued the bits of Jewish education they could manage in their forest camps, and valued am yisroel more than themselves; and there are no atheists in the foxholes.
I know hundreds of Israelis who have served in combat, religious and non religious, from the War of Independence until now – including my grandmother’s late cousin and his late wife, zichronom livrochoh, frum Jews all their life who served in the Haganah. I’ve never heard any of them describe their own valour in those terms. not once. I’ve heard them talk about nisim. I’ve heard them talk about HKBH’s help. I’ve heard them talk about the heroism and sacrifice of their brothers in arms. I’ve read their books and articles, I’ve seen them on film. Not ever, not once have I heard kochi veotzem yodi. I bet you haven’t either, except perhaps as described by someone who wanted to convince you that “di andere” are self centered morons blinded by their own sense of invincibility.
You make an assertion. Maybe its just conditioning. Maybe its reflexive. I’ll be dan lekaf zchus and assume it isn’t malevolent. But it is simply and utterly in grave error.
