NHK’s “NHK Special” looked closely into the Kim Jong Un regime, which has conducted repeated nuclear tests and ballistic missile launches. The program said it obtained 12,000 pages of North Korea’s internal classified documents that reveal how Kim Jong Un struggled to control the military through fear by executing senior members of the regime. The program also said the North Korean leader has become increasingly concerned about information flowing into the nation from overseas via the Internet or on DVDs or USB flash drives, including information about the assassination of Libyan leader Gaddafi, adding that Kim has repeatedly carried out public trials of those who have viewed or obtained such information. The files also revealed that nuclear development is viewed by the regime as the most realistic option to develop the economy and boost the nation’s defenses. The program said the fact that such classified files were taken out of the country suggests that changes are occurring in North Korea.
