I've been studying the subject a lot lately. It's not particularly easy to just 'switch sides' physically. Even the handful of nations who will sell citizenship (e.g., Turkey) do want upwards of half a million $$$.
You're studying something irrelevant. You don't need citizenship to pursue freedom in the
dictatorship country of your choice. Russia will happily hand out permanent resident permits to pretty much anyone, all you need is a job.
