Kim Jong Nam's denunciation towards his half-brother, Kim Jong Un was made public through the media. The eldest son quoted, "In that young man's expression I can see neither the mission nor the prudence of a man who has become the successor to a troubled country like North Korea, nor the expression of a man worrying about a future vision for the state." He also added, "In North Korea, the amount people who are earning money have to pay in bribes to high ranking officials in order to survive is rising. A corrupt system like this absolutely will collapse. It reminds me of the Soviet Union right before it collapsed." Kim also offered a withering critique that the people's trust in the North Korean leadership collapsed due to the failed currency redenomination. And further criticized the North Korean leaders, and Kim, Jong Il that the shelling of Yeonpyeong island was Kim Jong Un's act to justify the possession of nuclear weapons, and to emphasize his existence within the North Korean regime.
