ISW is not a serious publication. It's a neocon think tank that consistently got everything wrong from the start. If that's what you've been referencing then I see why you're confused. Meanwhile, we already see what's possible and not possible given that Ukrainian offensive has ground to a halt and failed to make any meaningful progress in around a month now. If you can't understand what an utter disaster this is from Ukrainian perspective then I really don't know what else to tell you. This summer will indeed clarify a lot of things for people.
