I know a lot about Ukraine history.
There fight for independence, their abuse by Stalin and others.
Year ago I had a long discussion with some Ukrainians. They were all excited about Zelensky and how is Ukraine turning better and better.
Of course, that is the problem. Putin does not mind poor and corrupt Ukraine, but hates when things turning well.
I'll do you one better: My father's side of the family LIVED a lot of Ukrainian history. My grandfather on my father's side was a Ukrainian Kulak, who narrowly avoided Stalin's Holodomor. He managed to get two sons out, but had to leave his wife and a daughter.
That kinda qualifies me as somewhat knowledgable about the Ukraine and its history.
