The parallel between Chia and Ceaucescu are not apt.
Romanians had access or knowledge from other Eastern Bloc news outlets. They knew what had happened in East Berlin, Czechoslovokia, Hungary before it hit their nation and the end came for the dictator.
North Korea by comparison is a Soviet gulag. They even consider information originating from China as criminal. There is no parallel between the final days of any communist eastern bloc nation and North Korea. I suspect that if the DPRK fell the ROK would be met with catastrophic costs and generations of former DPRK citizens that would never be able to adapt to life once their great lie was exposed as a great lie.
It is true that level of repression is an order of magnitude higher in N. Korea. Still, basic dynamic of ruling regime is more or less the same. The regime isolates itself from outside influence. Propaganda and domestic repression are ratcheted up, and the regime embarks on huge state project to reassert itself politically, trying to display it is still in control.
However, it is the last ditch attempt to mortgage whatever shelf-life it has in order to secure stable future, which is basically a fantasy.
N. Koreans know by now that they are living in a lie, but they do not realize how bad the lie actually is. That will become apparent when they experience outside life themselves, not just watching from video.
The threat of catastrophic cost is a leverage N. Korea used against its neighbors to have its way. However, leaving it alone become catastrophic, too, if N. Korea has nuke and ICBM, along with unending stream of outside aids(tribute.) It won't live quietly on handout. It will go out and maul somebody.
Another year we let Chia Head have its way, the worse is the consequence we have to deal with eventually. S. Koreans in general got tired. For all that they put up with, they got nothing.
