Netanyahu is under pressure to keep his coalition government intact. Two far-right partners have threatened to bolt in protest at any deal they deem to spare Hamas. A centrist partner, ex-general Benny Gantz, wants the deal considered. Hamas has provisionally welcomed the Biden initiative.
I’m pretty doubtful that much progress has been made to destroy Hamas. They use Israeli unexploded ordinance to make bombs which they now have more than they know what to do with, and they couldn’t ask for a better recruiting tool than this war. At a certain point you have to be realistic about the situation and realize they will have to deal with Hamas in negotiations.
