According to the Chosun Ilbo: North Korea has fired People’s Armed Forces Minister Jang Jong-nam after barely over a year in office, the fourth replacement in the job since leader Kim Jong-un took power in December 2011.
He has been replaced with rising apparatchik Hyon Yong-chol. Meanwhile Ri Yong-gil, the chief of the Army’s General Staff, has not been seen in public for two months, giving rise to rumors that he too has been replaced. There is speculation that Kim is trying to get the unruly and excessively powerful military under control by way of these frequent replacements.
These moves are only done in order to avoid the constitution of fractions in North Korea
