North Korea rarely airs its dirty laundry in public, but Kim Jong-un’s latest purge of a senior military official was staged for maximum visibility – a warning, analysts say, to generals growing too comfortable with their expanding economic power that they answer to him alone.“Kim is effectively telling military and party leaders: ‘Don’t even think about it. You are under round-the-clock surveillance,’” said Yang Moo-jin, a professor at the University of North Korean Studies.On Friday, Kim convened a rare joint meeting of the party, state and military – the first of its kind devoted specifically to corruption among senior officials, according to observers – to denounce former major general Pak Hui-chol in unusually public terms.Pak was, until recently, deputy director for organisational affairs in the Korean People’s Army General Political Bureau, a powerful institution tasked with enforcing ideological conformity, loyalty and ensuring the military stays subordinate to the Workers’ Party through an extensive network of political commissars and instructors.Kim Jong-un presides over a meeting of the ruling Workers’ Party of Korea’s Central Military Commission in Pyongyang on Thursday.
