The convention post WW2 was that the borders in Europe stay where they are, otherwise there is no end unfurling that. AFAIK Romanian-Ukrainian border is not contested.
I agree about the unfurling part, I was just trying to point out that the Ukrainian state crying about "the big bad Russian wolf" when that bad wolf is a major reason behind their actual foundation as a State is a bit hypocritical. Even more so when the Ukrainian state expects us, their neighbours, to join in in their battles against the Russians.

Got in to NATO, raise up the ladder!
