Northeast Anti-Japanese United Army
Kim Il-sung, later to become leader of North Korea, was a high-rank officer in this army, and attained a distinction that he invaded China-Korea border and attacked Japanese police station in Bochonbo 1939. It was widely reported by Korean presses such as Donga Ilbo and he became famous in Korea as the most prominent leader of the anti-Japanese movement. After the war, some of the Korean nationals in this army became the first generation of the leaders of North Korea. Besides Kim Il-sung, An Gil, Kim Chaek, Choe Yong-gon and Kang Kon were also Korean high-rank officers of NAJUA, later assumed high positions in North Korea.
Jang Song-thaek
Analysts of North Korean politics agreed that Jang's execution was the most significant since purges carried out in the 1950s by Kim Il-Sung, Kim Jong-un's grandfather and North Korea's founder; since 1960, purged top officials have not usually been killed, and the denunciations of purged figures have not typically been so extreme and public. Professor Charles K. Armstrong, an expert on North Korea at Columbia University, stated that "although high-ranking leaders, including members of the Kim family, have been deposed before, we haven't seen anything this public or dramatic since Kim Jong-un's grandfather Kim Il-sung purged his last major rivals in the late 1950s. This seems to indicate the divisions within the Kim regime were more serious than previously thought." Former U.S. National Security Council director for Asian affairs Victor Cha said that the purge and execution of Jang "tells you that everything's not normal ... When you take out Jang, you're not taking out just one person – you're taking out scores if not hundreds of other people in the system. It's got to have some ripple effect."
