I don't know, I don't think it's very good to be automatically dismissive of information purely on the basis of it coming from Western sources either, doing so is setting yourself up for a form of manipulation it's own. What you got to do regardless of the source is analyze the situation and decide for yourself what makes logical sense. Between going nuclear and capitulating to the West by doing nothing, conventionally armed ICBM strikes seem like a pretty a sensible retaliatory move on Russia's part if you ask me.
