North Korea’s elite are gathered in Pyongyang ahead of their biggest political conference in decades. Foreign experts say leader Kim Jong Un will likely use the meeting, which starts Friday, to push his expansion of a nuclear arsenal over the strong objections of the U.S., the U.N. and North Korea's neighbors, including ally China.
