There's pretty good internet access in most despotic countries, few of which have the advantages of social stability and breadth of surveillance apparatus as North Korea
Of course the likes of Lukashenko and Mugabe have seldom tried to claim that they're keeping their country perfect, and there's a risk that North Korea's propaganda is so unsophisticated it could end up looking utterly laughable even to pretty well-indoctrinated North Koreans[1], but its pretty hard to organise an effective resistance movement even when everyone in the country hasn't been educated in the values of the current regime since birth and the leadership hesitates to send entire families to gulags at the slightest provocation. It's worth pointing out that those who might be best to depose the Dear Leader, or at least undermine the hardliners in his inner circle, have had always had the privilege of access to communications with the outside world.

If people with access to the same education and media as us find ISIS' rather crass blend of simplistic theology and beheading videos to be sufficiently appealing to trade their comfortable developed-world lives to don burkhas and marry ISIS fighters, then people occasionally watching broadcasts appearing to challenge those approved by the propaganda police can quite happily continue believing in the probably less-absurd cult of the unique virtues of the Dear Leader and the nation of the cleanest people enough to not die in a protest.
