In 2016 , in the face of protests , South Korea decided to deploy the US THAAD anti-missile system . After North Korea 's fifth nuclear test in September 2016 , it was reported that South Korea had developed a plan to raze Pyongyang if there were signs of an impending nuclear attack from the North . A North Korean numbers station started broadcasting again , after a break of 16 years , apparently sending coded messages to agents in the South . As South Korea was convulsed by scandal , North Korea enthusiastically supported the removal of President Park Geun-hye , intensifying leaflet drops . In turn , Park 's supporters accused the opposition Liberty Korea Party of basing its logo on Pyongyang 's Juche Tower
