They were parts of Ukraine. Now, they are, de facto, controlled by the Great Russia.
De facto yes. But why should it automatically mean that they are not parts of Ukraine? When the Minsk agreements were signed, these parts were named as 'particular districts of Donetsk and Lugansk oblasts'. I think it implies that they are Ukraine, doesn't it?
In the same census majority of Kiev's population were Great Russians. Does it mean, that Kiev is the Great Russia's city?
As well as in the other big cities. The main administrative divisions in the Russian Empire were gubernii. I think it is more appropriate to compare in this scale.
But can you explain what is the difference between "Great Russians" and "Small Russians"? Why the USA should care, what group of Russians control few coal mines and rusted remains of Soviet industry?
I think the main difference is in political mentality. The Ukrainians are less inclined to have a czar.
I personally think that authoritarian rule was the main cause of Russia dragging behind of West European states economically and technologically.
The authoritarian rule of a relatively small group of people was one of the main causes of the Soviet collapse.
And now these guys have stepped on the same rakes.
About the second part of your question.
I think it is more appropriate to counter your potential enemy near its border, rather than near yours. It is the same reason why the US support Japan, S Korea and Taiwan in the Far East, and the monarchies of the Persian Gulf in the Middle East.
May be, it is because you are a clever, moderate, realistic-thinking collector, and right now you want to return Donbass only.
There is nothing to gather more, really. Talks about Kuban is a quite rare case in Ukraine, and I think that almost no one takes them seriously. Nothing to say about other Russian lands.
Really? Do you want to say, that Facebook group "Ruthenia Catholica" is about Roman Catholic mission in Ukraine?
----------------------
The word
Ruthenia originated as a
Latin designation of the region whose people originally called themselves the
Rus'. During the Middle Ages writers in English and other Western European languages applied the term to lands inhabited by
Eastern Slavs.
[3][4] Russia itself was called
Great Ruthenia or
White Ruthenia until the end of the 17th century.
[5] "
Rusia or
Ruthenia" appears in the 1520 Latin treatise
Mores, leges et ritus omnium gentium, per Ioannem Boëmum, Aubanum, Teutonicum ex multis clarissimis rerum scriptoribus collecti by
Johann Boemus. In the chapter
De Rusia sive Ruthenia, et recentibus Rusianorum moribus ("About Rus', or Ruthenia, and modern customs of the Rus'"), Boemus tells of a country extending from the
Baltic Sea to the
Caspian Sea and from the
Don River to the northern ocean. It is a source of
beeswax, its
forests harbor many animals with valuable
fur, and the capital city
Moscow (
Moscovia), named after the
Moskva River (
Moscum amnem), is 14 miles in circumference.
[6][7] Danish diplomat
Jacob Ulfeldt, who traveled to Russia in 1578 to meet with
Tsar Ivan IV, titled his posthumously (1608) published memoir
Hodoeporicon Ruthenicum[8] ("Voyage to Ruthenia").

Well, this passage supports your words.
I don't know whom this group represents. Catholics in Russia?
