Why do you say Ukraine is a Communist invention? It was created in 1917 by the February Revolution. Its precedent is the Kyivan Rus
No, it's absolutely not. Ukraine (namely, "borderland," there being at various times multiple ukrainas to denote territories near the borders of the Russian world) has absolutely nothing to do with Kievan Rus. The term itself was a Tsarist-era literary invention that was hijacked in the 20th century to serve the cause of Ukrainian nationalism. In the days of "Kievan Rus" itself, the term people from Galicia to Vladimir-Suzdal used was just "Rus," or "the Russian Land" (Russkaya Zemlya).
This is what results in the very peculiar Ukrainian nationalist sort of schizophrenia in which they propose to prosecute and imprison people calling Russia (aka the modern state), "Russia", or "Rus": http://lenta.ru/news/2015/07/07/radavsrussia/ In a way, they're sort of proving the point that Ukraine is an unconvincing fiction. If it wasn't, they wouldn't care.
