In any case, there was no Ukraine 140 thousands of years ago. There were no Ukraine 1000 years ago, The word "Ukraine" is apparently of polish origin. Poles named the fucking place.
The etymology of the work UKrayina is obscure, because the initial preposition could historically have meant "in", giving it more the meaning of "homeland" rather than "borderland". The Polish-Lithuanian Commonwealth did not even form until the 16th century, but the name predates that union. Hence, it is utterly absurd to claim that Poles had anything to do with naming the region. More likely, it originated as the name of a Cossack sich, and it was historically connected with the sich around Kyiv.
However, the entire etymology argument is irrelevant. Obviously, most of the countries that exist today either did not exist a thousand years ago or had very different boundaries. That cannot be an argument to justify the Russian invasion of Ukraine any more than the claim that Russian-speaking Ukrainians are really pro-Russian. It is utterly absurd to go to war on the basis of demographic patterns that existed centuries ago. What matters is where the boundaries are today and what the people living within those borders want, not what some strutting jingoistic Russian dictator, whining over a lost empire, wants. Barbos should be ashamed of himself for promoting this claptrap.
