Svinbra, kompis. 
Of course the repeal of the older law was never meant to “ban their language.” Just your standard nativist bigotry, meant, instead, as a hard slap right in the face of the country’s minorities - primarily, it seems, the Russians. Thank God Turchynov vetoed it. Even so, a very ugly episode, and one which rightly caused a lot of concern about which direction the country might be heading.
Speaking of, I wonder: Which direction is the country heading? Whatever happens to Crimea, I can only assume that Yatsenyuk and his pro-EU, pro-IMF, USA-approved lot will sooner or later get into a power struggle with the extreme right-wingers who serve (amongst others) in his government. If so, who will win? Who enjoys the greatest popular support?
Going by a quick and simple Wikipedia check, Yatsenyuk hasn’t really enjoyed a great deal of personal popularity so far - back in the 2010 presidential election, he received a humbling 6.69%. In the 2012 parliamentary election, though, his list did well, receiving 25.55% of the votes. The Ukrainians might grow to like him even more now, of course, if he plays his cards well.
Tyahnybok - the head of Svoboda - fared even worse back in 2010, with a pitiful 1.43% of the votes. In 2012, his party got 10.44%.
How things stand now, post-Maidan and post-Yanukovych, I do not know.
I guess Yatsenyuk and Tyahnybok are keeping it together, for now, due to a common external enemy (Russia) - but sooner or later, they’re gonna have to tangle, no?
