FILE - In this Thursday, Feb. 16, 2012 file photo, New North Korean leader Kim Jong Un, center, and senior political and military leaders, including his aunt, Kim Kyong Hui, third right, stand at attention at Kumsusan Memorial Palace in Pyongyang while reviewing a parade of thousands of soldiers and commemorating the 70th birthday of the late Kim Jong Il, picture in the background. North Korea's propaganda machine has long kept alive the myth of a serene, all-powerful ruling dynasty that enjoyed universal love and support at home. In a single stroke last week, that came crashing down. In attempting to justify the execution of his uncle, who was also considered the North's No. 2 official, young leader Kim Jong Un has given the world a rare look behind the scenes of a notoriously hard-to-read government.
