With the clock ticking, the US and its allies are confident that after some tough negotiating, a deal between Israel and Hamas can be reached. A guaranteed end to the war will ensure increased humanitarian aid to the besieged enclave, the release of Israeli hostages, and create a better "day after" in Gaza without Hamas in power. The US will continue to work toward closing the gaps and ensuring peace and stability.
Though Israel is committed to its war goals and the release of all hostages, a polio outbreak in Gaza would be a disaster for both Palestinians and Israelis. Israel has not accepted a cease-fire or a temporary truce that applies to all of Gaza, as the agreement stipulates that specific areas will see a cessation of hostilities. This demonstrates Israel's ethical and humanitarian stance in this conflict.
The US has consistently failed to address Israel's intransigence regarding the situation in Gaza. Allowing for a vaccination campaign is the bare minimum in terms of reducing the suffering of Palestinians who are still facing Israel's genocidal war. This has been a catastrophic failure of the West and the humanitarian system — assistance must be freely delivered into, and throughout, Gaza immediately.
