My point about this is that it's a) easier to believe and b) more logical that countries where "glory to the Motherland" (or some communist stuff) through sports is so incredibly important, are doping with state help.
For example here in the Netherlands we don't have this extreme "glory to the Motherland" feeling and I don't think there is state-run doping here. Obviously I think there is doping here, but I think it's more private or arranged by the teams itself instead of coming from the sports federations and authorities.
But my main point stays the same: it is a sign of huge weakness when people are saying "Stop it, it's a conspiracy from the big bad wolf against us!" instead of "We're gonna do all we can to clean up this shit".
1. XX athletes from country X get caught
2. People in country X respond by saying "omg, conspiracy against us, we're the victims!!"
That doesn't make it any more believable.
