This must rank as one of the more imaginative methods of retaliation against an arch enemy who claims to have just set off a hydrogen bomb. As the world frets and fumes over North Korea’s (alleged) thermonuclear weapons test and tries to figure out ways to sanction the rogue country, South Korea has gotten the first blow in – by blasting K-Pop across the border, on supreme-grand-immortal-leader Kim Jong-un’s birthday. Any kind of K-Pop, the wildly popular South Korean genre of pop music, is banned in North Korea, where citizens can only listen to government-run radio and TV stations. Some of the potent weapons in this unusual arsenal were performers like Psy, Girls’ Generation, Bang Bang and GFriend, among others. Check them out for yourself, in case you’re wondering what they sound like.
