A serious existential threat to the country from a targetable state actor.

Risk to Netanyahu's career or wellbeing can do the trick because as we have seen lately Israel is willing to risk Israel's future and the Jewish communities safety across the world. It's not even as a part of grand strategy or anything, they are pushing to make criticizing Netanyahu a taboo.

I used to admire Israel as the only sane country in the middle east with great culture for entrepreneurship even if they had elements of atrocities(these could be fixed through civil progress in sane countries). I'm genuinely sad to see it has turned into a genocidal theocratic lunacy like the rest of the middle east and theocratic lunatics can do anything.

If the calculus skewed by arrogance and religious delusions is on the positive for the ruling class, they will use a nuke.

Any serious attempt to stop the extermination in Gaza.
