Since Kim Jung-eun came to the forefront of North Korea regime, the relation ship of South and North Korea is slipping into the worst. The sinking of Cheonan warship by explosion on 26th of March, dramatic emergence of Kim Jung-eun at the end of September, the reveal of uranium enrichment facility on 12th of November, and the first time of attack to civilians after 6.25 war; firing artillery shells at the Yeonpyeong island on 24th of November, it seems like an elaborate scenario. Unlike Kim Jong II who had prepared to be a dictator almost 20 years, Kim Jong-eun had just 4 year s. Thus, Kim Jong-eun has a lot of difficulties to overcome to plant himself as a dictator of North Korea regime. Likewise Kim Jong II' s case, Kim Jong-eun needs the enemy from the outside to control inner dissatisfaction and to unite. They set South Korea as an enemy once again because South korea has not taken aggressive reaction despite of North Korea's provocations since the Armistice Agreement. The purpose of the North is to take over an advantageous position of negotiation by threatening South Korea and USA then making a quasi wartime condition. It seems North Korea has already set up this direction through the sinking of Cheonan warship, and as a sequence they are willing to do additional provocation. Of course there are nuclear as the last card of the North behind their provocations. Attack on Yeonpyeong island right after reveal of uranium enrichment facility is their artifice to maximize the impact of provocation. This implies they can carry out third nuclear test. Nevertheless Kim Jong-eun' s succession does not seem to be easy. First of all, economic crisis is the problem. Kim Jong II is carrying out provocations as a artifice to solve economic and succession issue, but economic situation is gradually getting worse by reason of economic sanctions and isolation through international cooperation. Furthermore, the attack on Yeonpyeong island seems to make it worse. Another problem is the nuclear. Nuclear issue was passed down from Kim II song to Kim Jong II and Kim Jong II has taken considerable benefit of it. But it does not seems to be very helpful to Kim Jong-eun. Because despite two times of nuclear test, they could not make certain result and they can not afford to advance to practical step. Thus, for Kim Jong-eun, nuclear might be quite probable of becoming a political hot potato.
