I wonder how crucial the US is to Ukraine now. I'm sure that since the original White House Meeting attacks they've fully appreciated that to Trümp at best "ally" means somebody to do your bidding and take the blame for self-inflicted problems. So they are bound to have been trying to lower their dependence but how successfully? (I guess nobody can know as they won't be making it public).Ukraine will only stop attacking Russian oil as part of a ceasefire (Zelensky)
Maybe the way the fighting has developed and where the US currently stands is making what remnants of US support are still there eg intelligence with hypersonic missiles, drones, no supply of interceptors, etc.. Plus I'm sure Ukraine already knows and keeps updated details of potential Russian targets.
