"Ukrainian is not a real ethnicity, it is a fiction created by the Austrian Empire to weaken their Russian rivals."
In a lot of the ways that matter, there
wasn't a "Ukrainian" nationality in 1910, but the Soviet apparatchiks in Moskow got up to a lot of shenanigans with language barriers and minor regional differences to divert unrest to local infighting instead of revolts against the USSR. Historically, the Cossacks make tracing the concept of "Ukrainian" into the Tsarist period a hopeless clusterfuck.
And because of aforementioned relocations, steppe nomad migrations (Crimean Khanate, lol), and more than a little action from Scandinavians ("the Rus"), calling
any nation in the area a clear ethnicity is a bold-faced
fucking lie. You're not getting clear haplogroups with any meaningful relation to modern borders there. Way too much traveling dickery going around, rarely entirely consensual.
"American is not a real nationality, it is a fiction created by the British colonial elite to justify not paying taxes."
There's a reason we're called "The United
States of America": The bedrock of the federal government is actually a coalition much like the EU (our current Constitution is actually the replacement to the comparably-toothless Articles of Confederation). With how intense the regional differences are, we're at least three nations in a trenchcoat. Had a civil war over it, in fact.
This is what you sound like right now.
Meanwhile, you're trying to excuse a "nation" defined chiefly by
indoctrination from genocidal warmongers as no different from a secession movement that took over a century plus the bloodiest-to-us war in our history to
start seriously looking at ourselves as one cultural body, or from exploiting mild language barriers and the narcissism of small differences to outsource oppression to local strongmen in a process that forces a lot more codification of regional habits than
remotely natural.
Ukraine is a quirk of imperial retention policies, the United States is the long-term aftermath of Colonial policy breakdown, while Palestine is the
present catspaw for the Arabs attempting to exterminate the Jews. They are still, right this
second, as the actions responsible for this thread show, defined primarily by refusing to let the loss in 1948 go.
