Comparing present day North Korea with 80s Romania is pretty far - the communist regime in Romania never had anything close to the same fanatical dedication from its people. Few in Romania ever believed the official propaganda, even if they were forced to spew it. In fact this is common with most dictatorial propaganda: no one believes it, it's more of a show of force - everyone repeating what they know to be a lie, least they get reported for wrong think.
By all accounts, this is not the case in N Korea - the propaganda there has been much more drilled into people, and I've even seen interviews with defectors saying that they still couldn't bring themselves to say bad things about Kim, or touching S Korean leaflets, for fear of divine retribution.
