Yesterday, North Korea's official state news agency reported the death of the country's leader, Kim Jong-il. He apparently died of heart failure, leaving behind his twenty-something son, Kim Jong-un, as his chosen successor. While experts expect some turbulence as Kim Jong-un takes power, they also note that the transition to the younger Kim has been underway for nearly three years. The leadership change carries the possibility of destabilization but also the possibility for a renewed diplomatic engagement as North Korea's leadership looks for ways to reinvigorate the country's failing economy. Veterans of both Republican and Democratic administrations are speaking out today to insist that negotiating with North Korea may be unpleasant, but it is also essential. The U.S. response demands a steady hand, calm instead of hyperbole and close coordination with regional partners - most importantly China and ally South Korea.
