Stalin did that in the 1940s by deporting all the Tartars and resettling the peninsula with ethnic Russians. Its kind of a Little Russian Island. Its demography, history, language and culture are vastly different from mainland Ukraine. Kiev held it with great difficulty in good times but the Maidan upheaval in February gave Crimean Russian separatists their long-sought after opening. Khruschev could not undo Stalin’s handiwork.
The solution to this is simple, as long as people focus on the fundamentals.
The former Warsaw Pact needs to embrace their own second amendment/federalist 46. And we need to jam the global market with btu: oil, goal, gas, nuke. I find it ironic Putin called us out as leaches...let us see mother Russia produce something greater than its cost that they didn’t pump out of the ground.
