I think the point is that what we today might think of as Cold War style rhetoric and rivalry has antecedents in the Russian empire and points earlier.
I would even go so far as to say the whole thing is from the Great Schism. One side has the Latin alphabet and Western churches. Another side has Greek-derived Cyrillic and Orthodox church. Note in this article, the Russians are said to be removing religious shrines and trying to get the Lithuanian language to use Cyrillic instead of Latin characters. Both of these kind sound strange, but it's not really accidental symbolism.
A couple months ago in the context of all the US-Russia political drama I was thinking of this... Some people say the current tension is trying to re-live the Cold War, but if you read about events from centuries ago the tension is all still there mostly in its present form. What if the whole point of conflict is really about how they learned to write and be Christians from Greeks?
