At the tender age of 27, give or take a year or two, Kim Jong Un is poised to become the world’s youngest commander in chief. Kim Jong Un presents the U.S. and its allies with an even more unknown character than his recently deceased father – and the strategic challenge of dealing with an inexperienced twenty-something who sits on a nuclear arms program, a stash of chemical weapons and the world’s fourth-largest army.
