Odd since it was America which instigated the Ukrainian coup, inflamed ethnic tensions, and continue to push towards military conflict.
No ethnic tensions really happened in Ukraine ever. Biggest problem I (as ethnic Russian and Ukrainian citizen) ever had was about spelling my name in Latin letters.
It's totally made up topic that just appears before elections.
You can use spoken and written Russian almost everywhere including contracts, court, communication with government employees, etc.
Yet, at Donbass and Crimea Ukrainians and Crimean tatars are threatened.
So yes, there are ethnic tensions now, thanks to Russian govt.
Heh.
