“Doubts grow” implies that anybody believed it in the first place. I don’t doubt that the administration preferred a ceasefire, but Netanyahu has pretty much no incentive to even try for one. If anything, his motivation would be to keep stringing along the current administration and make the war as bloody and nasty as possible, since that will peal away support for Harris. If Trump wins, he doesn’t have to worry about getting nagged anymore, he may even get increased support from Trump and carte blanche to go all out.
