My analysis:
1) This would be an isolated event, as in not even remotely related or prompted by whats happening in the Middle East. The country is so isolated, most people there probably don't even know where Egypt is, much less whats happening.
2) The KPA is so indoctrinated into serving Dear Leader, they will put these people down in a heartbeat.
3) China isn't going to say a word negative about NK's response. They wouldn't want to encourage any kind of discontent among their own people.
4) Nothing will probably arise from this.
T- I don't know about that.there are enough people with some money to afford cell phones, TV and cameras and computers. Cars vans and trucks and with all society enough people to become discontented to give the government a pause when thinking about loyalty.
This is a paranoid country that never allowes a single guard to patroll alone, if one makes for the border the other has to shoot them or die themselves.
I was told that at one time if a prisoner in a military jail in the USA escaped , the Marine in charge of him would have to serve out the prisoners sentence. This I do not know if it is just an old wives tale but a time or two that prisoners at the Castle escaped, the Marine in charge of them , had no choice but to find them or shoot them Could be a --no Shitter Sea story but this seems to be what is going on in Korea, on a larger scale.
The escapee from Korea has his whole family rounded up from infants to great grand parents and shipped off to the farms. Conditions are so bad there I cannot believe that the prisoners will have the strength to rebel.
Those that do stand up will come from the middle class, the educated and those that have the money to form well armed Militias. Those that have contacts outside the country and even with a home made ham radio can wait for the right time.
The time will come and I would guess that China is having hissie fitts as that idea may spread to parts of China.
