That’s for sure. To make things clear if you would try to identify a ‘historical Ukraine’ and not the artifical composition Communists assembled as Ukrainian SSR you’d find out it doesn’t include Kiev as well.
Im not well enough informed about where the border should be between EUkraine and Little Russia. I imagine the population of Kiev has changed over the years since the creation of an independent state, though I agree historical Kiev would have been Russian.
The point is, the current Ukrainian State is too large and has the wrong borders.
