The U.S. is watching North Korea very carefully today. North Korean dictator Kim Jong il, just promoted his 27 year old son, Kim Jong-un, to four star general. Why? Kim Jong-il, 68, is widely believed to have suffered a stroke in the summer of 2008. Since then he’s tried to make his third son the successor in what could be the communist world’s first back-to-back father-to-son power transfer. Kim took over the regime when his father and North Korean founder Kim Il-sung died in 1994.
