On a completely different topic, an idea came to me a few days regarding ways that Russia's cultural works might have survived...
Ironically it rests upon the Petrograd faction (who had already done the rest of the world a service by evacuating all the artwork and such into a bunker outside of the city before 4/10 leading to their survival unlike with Moscow) utilizing a tactic similar to its far less commendable ethnic slave bartering.
Specifically, bartering the works (art, literature, music, etcetera) created by "non-Russians" (meaning non-Slavic) to foreign governments, and their cultural institutions, for food and medicine, or just private collectors for cash. Much like with the ethnic bartering, it provides Petrograd additional resources AND removes a source of cultural "contamination" from the presence of "true Russians".
I find this idea fascinating as its a situation wherein pieces of Russia's cultural heritage survives due to the actions of the very faction that is the culmination of everything WRONG with Russia (and Humanity) BECAUSE that faction viewed it as worthless beyond what they could trade them for.
Thoughts? If the above is unclear or confusing please let me know.
