Pounding the table doesn’t make nonsense worthwhile.
Russia alone can end this war. The US cannot continue it, if they just leave. Nobody forced them to be there. Nobody is keeping them there. It is their war of aggression, for territory. Negotiating for anything besides “fuck off already” is pointless.
Stop blaming anyone else.
Stop pretending ‘you didn’t do diplomacy about our invasion, so the invasion marches on’ is anything but blame.
