The chances for a ceasefire do not look good. Why? Most of the leadership of Israel and Hamas want one, as does just about the entire international community. But Netanyahu and Sinwar do not. And ultimately, they call the shots.
Regarding Sinwar, according to the Wall Street Journal: "Hamas’s chief in Gaza, Yahya Sinwar, is in no hurry to end the war, believing that it is drawing Israel into a quagmire that is turning the country into an international pariah while reviving the Palestinian national cause, according to messages Sinwar has sent to mediators from Arab states. Hamas’s political leaders in exile, however, are eager to end the war provided a deal guarantees the group’s survival and grants it a continued role in governing Gaza."
As for Netanyahu, he gave a public statement saying, "We are working in countless ways to bring back our hostages. I think about them all the time. About their families. About their suffering. That is why we want to bring them back so far. But while doing so, we have insisted on the goals of the war, including eliminating Hamas. We are insisting we will do this and that."
Neither leader wants this deal. Therefore, it seems likely that these two will continue to fight, even while everyone around them wants this nightmare to end.
