You probably heard the news. North Korea – the land of secrets, Kim Jong-un, and various human rights abuses – has got itself a nice big bomb. Specifically, a massive, scary hydrogen bomb – a cute lil addition that will reportedly help them to “join the advanced ranks of nuclear weapons states.” Nice one guys.

Of course, while this is most likely not true, that hasn’t stopped some countries from taking action – and none have done so more effectively than South Korea. Just a light skip over the border, their neighbours have retaliated by doing what they do best: blasting some major K-Pop bangers over a massive borderline speaker system.

With a playlist that apparently features Psy, Big Bang, Girl’s Generation and GFriend, South Korea will broadcast songs, as well as propaganda, across the border and into the famously uptight state from noon today. “We have selected a diverse range of the most recent popular hits to make it interesting,” a defence ministry official told press. 

The act will be in direct defiance of North Korean rules, which only permit government-controlled radio stations and TV channels.  It’ll also be particularly annoying for leader Kim Jong-un – as today is his birthday. 

“Kim Jong Un isn’t your typical dictator,” a senior researcher at Korea Institute for Defense Analyses, Park Chang Kwon, told Bloomberg. “He’s a god in North Korea, and propaganda broadcasts raise questions among North Koreans about that. Broadcasts from South Korea can reach deep and far into North Korea’s society, imbuing the minds of its people with the images of a free nation and hurting the oppressive personality cult.”

It’s not the first time South Korea have done this, either. In August last year, the country created the same setup – blasting out propaganda and hits across the North Korean border, in what was later declared an act of “war” by the state. This time, some critics are worried it might be too reckless a move. “North Korea may react in an ultra-strong way to this decision by South Korea,” said Cheong Seong Chang, a senior researcher at the Sejong Institute. “(They could view) it as an act of ruining a national party.”
