Holodomor (or less)

The official Soviet version of the Holodomor is that Stalin put a strict Communist in charge of agriculture, and, while he knew Communism very well, he had no knowledge of agriculture, so Soviet agricultural production fell drastically, and many Soviets starved to death all over the USSR.

The Western Ukrainian version of the Holodomor was that the Russians stole all the Ukrainian food, and millions of Ukrainians starved to death.

Only the Western part of the Russian Empire was lost to Germany in 1917 during WWI, then Germany lost, but Britain, France, and the US all hated the USSR, so Britain and France took the lands lost by Russia during the war, plus lots of German land and a huge chunk of what had been the Austrian-Hungarian Empire, and redrew the map of Europe, forming countries with multiple ethnic groups, multiple languages, all weak and divided, easily controlled by France and the UK, and unable to pose any kind of threat to France or the UK.

One old story was:

'I was born in Austria. I went to school in Poland. I got my first job in the Soviet Union. And I retired in the Ukraine.'

'Oh, you must have done a lot of travelling.'

'I never left the village where I was born.'

Of course, there was no Austria before the end of WWI, Austria was formed as a small country after WWI out of a tiny bit of the Austrian-Hungarian Empire, and he was more likely Hungarian than Austrian, since large parts of Western Ukraine still speak Hungarian and have Hungarian signs and the people wear Hungarian-style clothes.

So the people who most rabidly denounce the Holodomor as something perpetrated on the Soviet Socialist Republic of Ukraine by the Soviet Socialist Republic of Russia were in Poland during the Holodomor, but were annexed by Stalin during WWII, when he took back all of West Russia that had been taken in 1917 by Germany, plus bits of what had been the Austrian-Hungarian Empire and Germany, and all were part of the USSR until the USSR broke up in 1991.

The final Soviet Socialist Republic of the Ukraine was put together by Stalin and Khrushchev, and had large chunks of what had been the Soviet Socialist Republic of Russia added to ensure that the final Soviet Socialist Republic of Ukraine had many different ethnic groups that don't like each other, making it easier to govern.

Now that the USSR is gone, those ethnic groups aren't all that happy together, and some want to be part of Russia, while others would love to help the US break Russia up into 20 small, unarmed countries with all those Russian energy resources returned to the rightful owners, US/UK/EU oiligarchs (but mostly US oiligarchs), for which they have been promised generous payment on the successful completion of this task.
