immediate ethnic cleansing
You mean the removal of the russian population that was occupying crymea? Besides those, I'm sure that there will be a lot of hate for russian speaking people, but tough fucking luck, guess why. Russian could have not invaded crymea and people would not have harboured hate for the ethnicity and language.
"Oh thanks for packing up and leaving, now my territory is destroyed and economy fucked up, thanks!" of course that people will blame tons fo thing in Russia, it's what I would expect of any oppressed population.
