So the success of any potential working-level talks could depend upon whether or not Kim decides that he will actually take some denuclearization actions. Is he sincere about being willing to denuclearize? Kim has said many words about being prepared to denuclearize, but none of that is worth very much unless he decides to act consistently with his words.At the very least, Kim could agree to demonstrate that he is prepared to begin denuclearization. Trump could ask Kim to start by surrendering just one nuclear weapon. If Kim does this, it would demonstrate that Kim is ready to take denuclearization seriously, and that his hardliners would not overthrow him for doing so.
