The June 2018 summit between President Trump and North Korean leader Kim Jong Un raised hopes for improved relations with this isolated Communist regime. North Korea has nuclear weapons, and long-range missiles capable of reaching the U.S., and the talks were aimed at ultimately removing the threat of a nuclear showdown. It’s far from clear, however, that North Korea will agree to dismantle its weapons. Diplomats also hope to negotiate a formal end to the Korean War (1950-53), which halted in a cease-fire but without a peace treaty.
