Without entering into the rest of this convo, do you really think releasing the hostages would end this?
I'd happily see the hostages freed (hopefully in a controlled enough means that no more get shot as the IDF assumed they were Palestinians) immediately, but I cannot pretend I think Likud and the IDF would accept that as an end to the conflict. Do you really think they wouldn't say that while the hostages were freed, the threat from Hamas remained, and must be dealt with, aka removing as many Palestinians as they state are Hamas and all civilians in their radius?
This isn't a linear path from October 7th that started on that day. This is a recurrent conflict that has colonisation at its root, and so long as Israeli leaders are allowed to ignore international law, annex land, murder civilians, pass legislation enshrining unequal rights, and massacre with the support of their military backers, this conflict will continue.
Netanyahu and Likud's leadership have made it very clear there is no intent for a peace that involves a two-state solution. The hostages have been used as pawns by both Hamas and Likud, and pretending that a wish for their freedom is the reason 30,000 Gazans are dead is ignoring the history of this situation.
