Yes, of course. They seem to think that acknowledging mistakes and misbehaviour will rob them of their power since that power partly depends on them never being wrong. They must realise that anyone and his dog knows by now this is a total fiction but for some reason they just can't get themselves to step up, bow down deep like you sometimes see Japanese CxO's do when taking blame for some misstep and humble themselves before their nation. Given that the same phenomenon has characterised more or less al other "communist" regimes it seems to be something in this ideology/doctrine which makes it near to impossible to admit to failure.
