I don't know about you, but I find these "pro-West" side to be quite specious in their arguments. What idiot really believes that Russia of all people would want to kill their own golden goose ?
The argument these geniuses are implicitly making is that either Russians (or more euphemistically "Putin") is a raging lunatic, or that their readers so utterly dim-witted that they'll believe any shit that they'll spin.
OTOH, US/UK... has a very long history of false-flags and extremely sophisticated psychological warfare, esp. given the international dominance of the English language.
