That fits the American and official Israeli narrative.
People in DC told me that McGurk is so invested in the failed negotiations on a bad deal that it is difficult for him to let go and adopt the #threeweeksdeal.
My understanding is that if Israel were to tell the mediators that the three weeks deal is acceptable, Hamas would return a positive answer too. To me it seems that there is either the three weeks deal or no deal.
This war must end and the hostages must come home. Now!
