Kim noted that the execution was to solidify Kim Jong-un's sole leadership but public dissatisfaction within North Korea will grow over the "politics of horror" in the long term. The regime then is likely to use the traditional strategy of cultivating a sense of insecurity by for example testing another nuclear bomb or test-launching missiles.
On Monday, North Korean military disseminated thousands of provocative leaflets towards Baekryong-do, a South Korean island situated close to the North-South border. The messages read "we are ready to strike at any time," "Baekryong-do will become a huge grave" and "Run away if you want to live."
South Korean Ministry of Defense is not taking this seriously though saying these leaflets are nothing new. The last one was in October 2012.
