Like father, like son. Since the recent death of Kim Jong Il, North Korean state-run media has been releasing a series of images of the "Great Successor," Kim Jong Un, visiting schools, factories, and military facilities. These visits, which were frequently publicized by his father and his grandfather Kim Il Sung, are called "field guidance" trips -- opportunities for the supreme leader to give on-the-spot advice. For decades, the North Korean myth-making machine endowed Kim Jong Il with amazing wisdom, prowess, and intelligence, and it continues that tradition now with his son, touting him as a marksman, poet, economic genius, and wise military strategist. Little is actually known about Kim Jong Un. Even his age remains in doubt -- he may be 28, 29, or 30. Based on the state-released photos collected here, he is following closely in his father's footsteps, albeit with a touch more visible affection.
