Experts expect talks to focus on limiting North Korea’s arsenal rather than immediate denuclearization.Nuclear goals narrow: Washington may increasingly favor freezing nuclear production and pursuing gradual reductions, reflecting doubts that complete denuclearization remains achievable.Pyongyang holds leverage: Stronger military ties with Russia and closer relations with China have reduced North Korea’s dependence on US concessions, giving Kim greater freedom to reject unfavorable terms.Seoul faces risk: De facto US acceptance of North Korea’s existing nuclear arsenal could leave South Korea exposed to a permanent nuclear threat and intensify debate over its long-term security options.Concessions likely demanded: Pyongyang could seek sanctions relief and reductions or suspension of South Korea-US military exercises in exchange for limits on further nuclear development.Summit needs groundwork: Experts say working-level negotiations should precede any Trump-Kim meeting to avoid repeating earlier leader-driven diplomacy that produced engagement but no lasting nuclear agreement.
