Palestinians only have one method of resistance left, and that's violence. Telling them to not use it because Israelis might get hurt is, and I'm sorry to say this, frankly ridiculous. If Israelis don't want to get hurt maybe they should give Palestinians the state they've been asking for for forty years. I understand your concern, but the onus to prevent this outcome is squarely on Israel; as colonized people Palestinians have the right to use all means necessary to obtain their freedom.

That said, you're most likely worrying over nothing. Hamas doesn't have the capability to overthrow Israel; their operations mostly serve to lose Israel face on the international stage. The only scenario in which Israel falls is if America completely leaves it out to the wolves and the middle east tears it apart, which is extremely unlikely.

Most citizens of Israel have not brought it upon themselves.

Okay I understand the reflex to explain how governments don't represent their people, but look at this and you might wanna reconsider. Netanyahu didn't come out of nowhere; he came in when the only man in Israeli history who had the potential to actually end the conflict was assassinated (after Netanyahu and his ilk went in parades calling for his assassination) and since then it's all been genocidal maniacs (save for one guy in 2008 who still didn't have the guts to actually do something worthwhile), mostly Netanyahu himself. Now I don't believe in "push the Zionists into the sea" rhetoric, and the only time it was realistic was in 49' anyway, but the conduct of the Israeli public these past few months in particular and in the past 30 years in general has been nothing short of fucking disgusting. If Israel does fall and they're persecuted by the new regime, anyone who wasn't explicitly pushing for peace (and children and the like of course) is getting nothing but Schafenfreude from me.

All of this is excluding foreign-born citizens of Israel; anyone who willingly went to that place and isn't explicitly calling for peace is a piece of shit.
