To clarify my view in this discussion:
Hashem fights for our physical survival (this does not mean that
there’s no rule of “Habo l’harg’cha hashkeim l’hargo”), and we fight when He presents us with a violent challenge to our Yiddishkeit. (That’s the ideal, anyway – see Logician’s post.)
“[T]o preserve or restore Jewish sovereignty” is not something
Chareidim believe in fighting for as an ideal, and historically
speaking, lack of a Jewish government in Eretz Yisrael has not
prevented us from living there, so the country in question being
Eretz Yisrael doesn’t matter.
So, were a foreign power to give a Chareidi government,
in Eretz Yisrael or elsewhere, the option of peacefully
surrendering to them (becoming subject to foreign taxation, etc.),
I think we’d take it. Does anyone here disagree?
