I know Owlbread is suggesting a Crimean Tatar Republic out of a good-natured idealism (which I respect), but I really don't see how this could be feasible. The Tatars are too small a minority and it's way too late to try to reverse that now.
I also doubt a civic Crimean national identity (that includes the Russians and Ukrainians there) is realistically possible anytime soon and with the current wave of nationalism in the general area, I don't see something like that happening in Crimea at all.
Civic nationalism is a shaky work in progress even in the countries where it is actively tried, often it is civic in name only. It works somewhat better in the colonies than in Europe, but it's still very noticeable how for example the American national identity used to be a WASP thing, or that French civic nationalism is as French as their laizism is Catholic (almost like Turkey where the government likes to pretend ethnic and religious minorities don't exist). German politicians (and I'm sure it's similar in other European countries) have been advocating a civic national identity for decades, but I don't think that has really trickled down into the public consciousness yet.
But what saddens me more: majority of foreigners tend to ignore Russian crimes with that "USA does ad things, too!" argumentation
Well, there is a lot of latent anti-Americanism in Europe. Also, between the big players (US, China, Russia), Europe is or rather perceives itself as helpless and is thus eager to avoid conflicts.
Similarly the population (at least here in Germany) is upset about violence in [insert African or Middle Eastern country], but doesn't want a military intervention there. If the US stages one, it's jingoistic imperialism and because of the oil. If they don't, it's because they don't care, their diplomacy has failed or because the country has no oil. That's the hypocritical pacifism I mentioned earlier. Maybe I should write a protest song about it, because that's the only proper reaction to anything...
