Yes, it's funny how there is a lot of fear about a country that attacked noone since the Korea War (and that didn't commit massacres during it unlike their opponent), especially when those people are from a country that have a carte blanche to attack other countries and do it on a regular basis.
NK rulers aren't idiots, they have access to the West (media and travel) and they know about the relative military strength and probably aren't to keen to have Democracy™ being forcefully implemented on them.
