Edit: It looks like the argument here is that the US is not calling for an instant ceasefire, but instead saying that one is very important to have. China and Russia say it should be immediate. The US also tied it to hostage talks.
Another resolution is in the works to call for an immediate ceasefire, but the US is expected to veto it because they believe it could endanger hostage talks.
Indeed they should. Which is why the resolution includes demanding the release of hostages held by Hamas and Israel.
It’s calling for a temporary ceasefire, similar to the temporary ceasefires Israel has called for. The US has veto’d the last three calling for a permanent ceasefire and release of hostages, similar to how Israel has rejected every permanent ceasefire and hostage release deal Hamas has called for for months.
Israel continues to prioritize the extended bombing and famine in Gaza over getting the hostages released.
