Oct. 30 (UPI) -- When Donald Trump declared aboard Air Force One that he was "100% open" to meeting Kim Jong Un during his Asia tour -- and even acknowledged that North Korea is "sort of a nuclear power" with "a lot of nuclear weapons" -- it became clear he was sincere about rekindling dialogue.

Yet Kim Jong Un has shown no willingness to respond. During the APEC Summit in Gyeongju, a Trump-Kim encounter now appears highly unlikely.

Still, if and when Kim eventually chooses to answer Trump's renewed signals, there are three proposals that would be most suitable for opening a fresh chapter -- one that avoids empty theatrics and lays groundwork for meaningful diplomacy.

Even if political theatre surrounds any future engagement, the stakes remain serious.

For the United States, the core objectives are unchanged: preventing North Korea's permanent nuclear status and advancing accountability for human rights abuses.
