This is how they refuse a deal: Israel and the US are pushing aside the agreement to release the abductees with their own hands. The first hostage agreement was infinitely simpler.
Each day a specified number of abductees and security prisoners were released. This is what allowed the realization of the deal and the extension of the ceasefire. On the other hand, last month Ariel Kahane published in "Israel Hayom" that the US at one point wanted to hitch a deal to end the war in exchange for normalization with Saudi Arabia.
