Certainly, not every Israeli agrees with settlements. But the largest demographic in this poll does. They view the settlements as favorable.

No, they think the settlements in the West Bank improve security - a different question than whether they "agree" with settlements. And a majority of Israelis are against settling Gaza.

As long as the idea is there, and the funding is there, you can't kill it.

Perhaps - but you can weaken the implementation of it. You can't stop Iran from supporting them, I agree. But switching out a battle-hardened and experience veteran for an inexperienced one is something.

But again, this is the "no good outcome" conundrum that Israelis face. The "idea" of Hamas is that all the Jews in the region need to be killed or expelled. If you can't kill that idea, then you just have to resign yourself to fighting it forever - and take steps to try to minimize the damage the idea causes. One approach to that is to try to degrade whatever organization has currently taken up the mantle of trying to kill or expel the Jews, even if that's a Sisyphean task.
