Experts: Prospects for Future US, North Korea Talks Grow Dim Christy Lee WASHINGTON - North Korea's insincerity toward denuclearization and its demand for greater U.S. concessions are making the possibility of serious working-level talks with Washington dim, experts say. "I don't think there is much prospect for real progress in dismantling (North Korea's) nukes," said Robert Manning, a senior fellow at the Atlantic Council. "It's possible Kim Jong Un will order (his negotiating team) back to the table, have several more sessions, so there's an appearance of sincerity." The long-stalled working-level talks between Washington and Pyongyang resumed Saturday in Stockholm and ended unsuccessfully without making any progress toward denuclearization. .
