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.
Israel the modern state shouldn’t exist, not at all. It’s an Apartheid settler colonialist state and much more of a terrorist organization than Hamas. Now whether Palestine should be partitioned with one part given to Jews that’s a different debate, but even then that should be a new state built from the ground up with an actually fair constitution and international supervision. I say even then because I believe one democratic state is a lot better than two states that are likely to go to war with each other and much more liable to become Apartheid states.
