In theory the hostage situation ending should put significant additional pressure on Israel to back off on its retaliation.
Even if it’s widely agreed that their retaliation is extremely disproportionate, if their public rationale is partly “we’re combating the people who attacked us and took two hundred hostages we need to rescue” - once the hostages are all accounted for the immediacy argument goes out the window and they are left with either admitting the continued efforts are about expanding settlement or stepping things back.
Honestly if the hostages are rescued and they continue the bombing and forced migration (which I expect the administration would like to), it’d likely spell the end of the extreme right wing in Israel.
If Hamas were smart, they’d immediately release the hostages still alive unconditionally and return the dead, forcing Netanyahu’s hand in either de-escalating or cutting the BS in what this is really about and facing the consequences internationally and domestically.
Though that would also mean a more moderate future Israeli government, which isn’t necessarily what Hamas wants or is aligned to their goals, so even though that’s what would be good for the Palestinian civilians, I’m doubtful it will happen and we’ll instead have considerable future bloodshed.
