They are driven more by self-preservation than any love for the nation or Kim Il Sung. They would served anyone who feed them. His cronies had purged those who could have and wanted to built a strong, rich nation. All he had left was shameless and useless sycophants like Hwang Jang Yup, who would and did leave the sinking ship at the first opportunity. A few months before his death, Kim Il Sung confided to Jimmie Carter that he had made many mistakes, but no regrets can undo the wrongs his Party hacks had done to the Korean people or bring back those killed by them.
Life goes on.
It is encouraging to see Kim Jong Il undoing some of the wrongs perpetrated by the Party gold-diggers who surrounded and suffocated his late father with incompetence. Kim Jung Il has restored some of the purged nationalists, restored some semblance of democracy and nationalism, and has the economy moving. He has replaced useless Party hacks with young technocrats. He even had the courage to execute high-ranking party cadres for corruption. I wish him good luck, and should he want or need my help, he will have it.
