Not possible. End of post.
Well, yes...but that doesn't mean we can't think about possibilities. Occasionally when I mention to other North Korean watchers that I do research on social movements, I get asked about the (lack of) prospects for a social movement in NK.
Here was an email I sent in response to a comment about social capital and civil society in North Korea
As for social movements, yes, most people discount an Arab Spring for NK b/c it lacks civil society. But in the study of revolutions (not that i'm advocating a revolution in NK) there is something known as preference falsification where people convey their preference for social conformity in public while holding different thoughts privately. So N.Koreans praise the regime in public while holding genuine thoughts to themselves. A side effect of preference falsification is the dampening of knowledge and information and an inability to gauge true level of discontent. So no one complains despite hardship. Under certain conditions though, private thoughts may emerge in public which may embolden others to convey their true preferences and demand for change. One of those conditions is probably the existence of information networks (or social capital if you want to call it that) so underground churches could play that role. In places like E. Germany where this theory was applied (by an economist, Timur Kuran), a network of both underground activists and some associational life (workers unions) brought safety in numbers once grievances were expressed out into the open forced regimes to make concessions.
One research I'd be curious to explore is whether development projects or something like the Kaesong Industrial Complex foster trust networks and social capital among North Koreans. Likewise, I wonder if there are there trust networks built among migrants who cross borders between NK and China as the come into contact with one another.
Perhaps we need a network
