Hey there, time traveller!

Purges in Communist states have rarely stopped with the execution of one senior party member, especially when he has been tortured into "confessing" at his show trial that he was planning to stage a coup using "high-ranking military officers" and other close allies.
"I didn't fix the definite time for the coup," Jang Song Thaek, the former No. 2 in the hierarchy of the world's last totalitarian state, said at his trial. "But it was my intention to concentrate (my allies in) my department and in all the economic organs in the cabinet and become premier when the economy goes totally bankrupt and the state is on the verge of collapse."
It's most unlikely Jang was really planning a coup, but all of his suspected allies and associates in his own department and other parts of the government, plus any senior military officers suspected of less than total loyalty to Supreme Leader Kim Jong Un, are in grave danger. Only two of Jang's aides have been killed so far, but hundreds or thousands of other people thought to be linked to him may suffer the same fate.
This is unquestionably the biggest internal crisis in North Korea since the early years of Kim Il Sung, the founder of the regime and grandfather of the current dictator. Challengers to the Kim family's monopoly of power have often been killed, but this is the first public show trial in North Korea since 1958.
It's also the first time the regime has publicly admitted there are rival factions in the senior ranks of the Workers' (Communist) Party. It's hard to believe this will not be followed by a wider bloodbath among the leading cadres along the lines of Stalin's purges in the former Soviet Union and Mao Zedong's in China. It's harder to understand what is driving the current upheaval, but some plausible guesses are possible.
When Kim Jong Il, the father of the current ruler, was dying, he chose Jang as the man who would ensure a smooth transfer of power to his son. (He was married to the elder Kim's sister, and was therefore presumably loyal to the family.) Jang acted as chief adviser to Kim Jong Un, who was only 28 and quite inexperienced when he inherited the leadership in 2011, and Jang's manner sometimes seemed quite overbearing.
So we can speculate that Kim Jong Un, as he gained confidence in his own abilities, grew increasingly hostile to the dominating influence of Jang, who was more than twice his age. He would need allies before he moved against Jang, and many military officers were glad to oblige.
On this reading of events, Kim wants to get rid not only of Jang but of the entire generation of older military and civilian leaders who secretly regard him as an upstart. His objective would be to replace them wholesale with younger men who owe their positions directly to him. Or maybe something else is at the root of all this turmoil: We simply don't know.
What we do know is there is great turmoil in North Korea, a nuclear-armed country with the fifth-biggest army in the world. Most people assume at some point in the future the regime will collapse, and some well-informed people worry the collapse could come quite suddenly and quite soon. Interestingly, almost nobody wants that to happen.
Neither North Korea's Chinese neighbours nor South Korea's American allies want it to happen, because the collapse of the Pyongyang regime could bring them into direct conflict. As a recent study by the Rand Corporation pointed out, it would cause a race between Chinese troops and South Korean and American troops to take control of North Korea's territory.
The Chinese would be determined to keep American troops away from their own border with North Korea. The South Koreans and their American allies would feel compelled to go to the aid of a North Korean population that would probably be facing starvation by then. And both sides would be racing to gain control of North Korea's nuclear weapons before something terrible happened.
In such circumstances, a collision between Chinese and South Korean/American forces is all too easy to imagine. Kim Jong Un is a very nasty piece of work, but a lot of people are praying for his survival.
