Almost the entirety of Israel has been propagandized to regard Palestinians as vermin from the earliest ages in the education system.

And vice-versa, to be sure. One isn't going to get a favorable, or even nuanced, view of what Israelis are like coming up through the Palestinian education system, either. It is a major obstacle to the two peoples living together.

It's entirely possible that the fighting resumes, but Netanyahu has some very strong incentives for that not to happen. His right-wing coalition partners may be agitating for it, but Netanyahu has put all of his eggs in the Trump Basket and now can't afford to cross Trump. Plus, with the hostages out, he's now lost that section of the Israeli electorate whose support for the fighting was motivated by getting them back - renewing the fighting won't be nearly as popular as the beginning of the war (which was near-universally supported). Propaganda or no, after a few years people get weary of war; and in this case, also weary of the rest of the world condemning them. So I don't think Netanyahu has the ability to bring Israel along with him for a march back into full-blown invasion mode again.
