If American propaganda sites such as BBC and CNN are trustworthy, then the Sputnik News is also a trustworthy source. And the fact that the Americans are supporting the neo-Nazis in Kiev is an open secret. The Americans have supported the openly Nazi Yatsenyuk against the much more milder (but at the same time schizophrenic) Poroshenko. Also, most of the violence during the American sponsored Maidan coup was committed by the Nazis.
First of all BBC is British, second CNN is not the only media in USA, thirdly there is whole Europe that can provide useful informations. And finally claiming that every Ukraine person that wants to join EU and not Russian Eurasian Economic Union is not a Nazi.
The BBC is pretty much state TV for all intents and purposes, it's often portrayed as 'leftwing' by some but its complete horseshit. They toe the line and preach whatever the government wants them to, including propaganda for our cousins over the pond due to the 'special relationship' we have.
