Thus all official Russian or pro-Russian sources should be considered full of shit until proven accurate. The standard of proof should be very high when their claims are considered.
The problem is that this can be said for every news media outlet and every state. Everyone has an agenda these days and we can assume that almost everything we hear or see is not the "truth". Recent technology has only made this worse.
My point was that you can reasonably expect this to be MUCH WORSE on the Russian side. The assumption you are making here is exactly what the Russians would want you to make.
Information warfare is the only arena where Russia is actually stronger than the West. They've perfected it and its victims are numerous.
I recommend Geir Giles' book Russia's War on Everybody: And What it Means for You.
