It has been declared many times already at GT and here: I'm not Russian but I'm living in Russia for 2 decades already. And I know situation from inside.
My point of view on situation with Crimea is very clear: Russia broke some law, but save people of Crimea from neo-nazi and nationalists. Without that Crimea now may be been East-European Rwanda already. The "power engine" of Ukrainian revolution - Maidan - at November 2013 March 2014 been nazi batalions from West of Ukraine and nationalistic parties like "Pravy Sector" ("Right Wing") and "Svoboda" ("Freedom"). Do you remember Rwanda tragedy?
