The problem is that right now, Israelis feel like anything other than obliterating Gaza is a fantasy that cannot work. But see my comment here: https://news.ycombinator.com/item?id=39152982 There are only three ways it can end, two involve both sides showing some trust, and the third involves war crimes. Given the carnage to both sides means trusting each other is unlikely, that takes us down to the "fantasy" of trusting a third party, or war crimes. Take your pick.
