Yes except Russians run the fucking USSR. What is your point? I don't care what you call it. For all practical purposes it was a Russian Empire.
Nope. It was not. If that was the case, then why Crimea was separated from the Russian SSR in 1954, and gifted to the Ukrainian SSR? At that time, the peninsula was overwhelmingly populated by the ethnic Russians.
In order to Crimea was conditions of life for the Crimea joined to Ukraine. Ukraine dug a channel and put fresh water in the Crimea. Additionally, the supply of the Crimea more convenient to do it through Ukraine.
So you are saying that just because Ukraine is providing fresh water to Crimea, the peninsula must surrender its sovereignty and merge with Ukraine? No that is not going to happen. Crimea will remain as a part of Russia, because the overwhelming majority of the population want that.
There are two options for the development of events. 1 is to do everything legally correct And quite the opposite elections, this is to do as the local population wants to do. That's only the local population is the Tatars, and not the Russians. Although, frankly, a simple person has never depended on anything, because I was not only used for them in other purposes.
