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 hope it sticks also. Regardless of success, it puts Biden in direct oversight of negotiations and circumvents the State Department. His restored sanctions on Israel’s expansion leave Netanyahu with no requests other than hostage return and ceasing inbound attacks. If they fail the ceasefire over desire for retribution or expansion, Biden has a first hand account of justification for amendment of support without challenge from Congress.
