North Korea is politically stable and will likely remain so for the foreseeable future. The Kim family regime has weathered all conceivable challenges to its rule and is essentially unchanged for the past 70 years.

This stability is often attributed to the exceptional brutality and efficiency of the DPRK system. While this no doubt contributes to its staying power, there are other factors at work. 

And one is a uniquely effective network of surveillance and indoctrination that no North Korean can evade. Big Brother exists, and he’s in North Korea, monitoring every action done and word uttered by the people.
