On Wednesday, a ceasefire deal between Israel and Hamas was lauded both by President-elect Donald Trump and President Biden in his farewell address. But as of Thursday morning, the talks among the parties are in “crisis,” according to Prime Minister Benjamin Netanyahu’s office, due to a late demand by Hamas that has delayed final approval of the deal.

Under the proposed agreement, Israel will release terrorist prisoners in exchange for the release of 33 hostages (both living and dead). But, per the Times of Israel, Netanyahu’s office said that there was “a last-minute attempt by Hamas to withdraw from a clause in the agreement that grants Israel veto power over the release of mass murderers who are symbols of terrorism.”

Since Israel cannot agree to any deal that would allow Hamas to secure the release of the worst of the worst terrorists, the cabinet is delaying the final cabinet vote.

It is unclear as of this writing whether this is a just a snag that will get dealt with and allow the deal to get approved later in the day. Or, whether Hamas is hoping that Israel can be pressured into more concessions given that both the incoming and outgoing U.S. administrations have announced a deal and are heavily invested in it going through.
