Idk for this case but in many authoritarian countries anti-corruption is often a nominal goal while the real target is something else that may not sound as noble… even while targeting legitimately very corrupt people.

The whole ruling clique may easily be skimming from wherever they can (so long as it’s not too egregious or clearly harmful to the goals of their leadership) as one of the perks for being up there which is an easy way for leadership to buy loyalty of subordinates. That also makes those subordinates “dirty” since their leadership that watched it happen has great evidence to cite if for whatever reason they are not satisfied or impressed by the underlings who partook. Then those lower people can be cracked down on (even legitimately!) for corruption even if their real crime in the eyes of the government was on dissenting about a certain policy or the like. Tasty carrot as bait to partake and later fear of the stick of exposure and punishment.

North Korea’s ruling Workers’ Party has reshuffled the country’s military leadership.

Ah okay, so now he gets to draw…8 new military leadership cards. Alright, who’s turn is up next?

In July, Kim Jong Un instructed that military discipline be tightened, following a corruption scandal involving senior military officials. South Korean media say the reshuffle is intended as part of this anti-corruption campaign.

Sure, and the fish are working on their anti-water campaign.

Beyond that, it’s pretty hard to make heads or tails of this, since information is so restricted. Even people who study NK for a living seem like they’re doing guesswork.
