This is not a desirable situation to US interests. Israel has to offer terms acceptable to Hamas - Israel cannot just offer terms acceptable to the US. If the two parts needed for peace were the US and Israel, then the US would have sold out Palestine long ago to whatever conditions Israel wanted to impose.
And it is still very much a war. Just with a civilian genocide going on simultaneously. Israel still hasn’t managed to overcome Hamas partisans in parts of Gaza (which, considering their sheer lack of care for collateral damage and overwhelming technological and organizational advantage, is an incredible condemnation of the IDF’s lack of competence).
