Finalyzer, I'm sorry if you took any of my comments personally, I didn't mean to offend you in any way. They point that I was trying to make is really the same. You are unable to validate the analysis by polit.ru, that is not a reason to deny it as a valid reference. That's really the idea of WP:OR. The fact that you think that their references are irrelevant to their conclusion, or unreliable doesn't make them invalid references, unless you can find a source to validate your judgement.
