The only party ignoring and abandoning the hostages and foreign nationals stuck in Gaza (whom you conveniently do not mention) is Israel.

Hamas would definitely be willing to give back hostages in exchange for concessions. And they also were willing to let foreign nationals leave, but Israel blocked the border, leading to the death of at least one of my countrywomen.

But Israel is blinded by rage and opporunism, so it prioritizes stealing land in the West Bank above freeing hostages.
