Why Kill His Uncle?

Were you puzzled by North Korean leader Kim Jong Un executing his uncle and mentor Jang Song Thaek? Writing for The Daily Beast, Gordon G. Chang lays out some possible reasons for the execution. For example:

Jang introduced Kim to his eventual wife, Ri Sol Ju. According to a growing number of accounts, Jang also had an affair with her.

Furthermore, there are reports that Jang and Ri were somehow involved in a sex tape. In any event, she has not been seen in public since October. Kim Kyong Hui, Kim’s aunt, supposedly approved the execution of her husband. 

This sounds like a summary of the year-long plot of a TV soap opera, or the script for a North Korean version of 24.
