One issue is that Russians are going to be biased in favor of their country. Stalin's got a 70 percent approval rating.

But there is a further problem of how the Russian government keeps citizens in the dark. Journalists are murdered and arrested. A point about how disinformation works is that it isn't about getting the public to believe things that aren't true, but to get them so that they can't identify what is true, and thus ignore all news. The soldiers tend to come from poorer, rural provinces, which means less news about deaths gets out in Moscow or St. Petersburg, and that people dealing with the tragic death of neighbors and relatives are already isolated which makes lying and manipulation easier.
