I mean, the IDF have basically found the one "solution" to an entrenched guerilla populace. Mass ethnic cleansing and genocide.
The reason why the Taliban and all the other extremist groups could rely upon "kill one terrorist and you make five more" is because even the Soviet Union didn't want to completely wipe out the populace of Afghanistan. The IDF has demonstrated they have zero qualms about that. You have family members full of resentment... until they get murdered too.
And it isn't like neighboring countries will accept many Palestinian refugees that will become (yet another) force in the future. Palestine has pretty much always been supported only as far as it inconvenienced Israel with no nations actually caring about the people.
I wish peace were on the table. But the idea that the IDF can't "win" is ignoring the reality of what they are doing.
