Unwilling or unable? Netanyahu hated Biden and has done everything in his power to sabotage anything Democrats have done to try to help resolve the conflict, even prior to Oct 7.
Trump let Netanyahu run roughshod, and the proposed peace agreement (which almost certainly won't hold) is pretty... let's say vague... about the plan for Gaza post hostage-release.
All that's happened here is another agreement to exchange hostages for prisoners, which has happened multiple times in this war already. Not much else is actually agreed to and obviously even less has actually happened.
