South Korean President Lee Jae Myung has proposed a phased route towards North Korea's denuclearisation, beginning with an effort to stop the further expansion of Pyongyang's nuclear and missile capabilities.

In an interview with the Associated Press, Lee described a sequence that would first halt new advances, then roll back the existing arsenal and ultimately pursue dismantlement. The proposal recognises the distance between an immediate freeze and the final goal that previous negotiations have struggled to reach.

A step-by-step approach can make diplomacy easier to test: each stage can be linked to inspections, reciprocal measures and a clear record of what has actually changed. It can also create room for talks when the parties do not agree on the end state or on the order of concessions.

That flexibility carries a risk. A temporary halt could become a permanent acceptance of a nuclear North Korea if verification is weak or political momentum disappears. Any process would therefore depend on what is counted as a freeze, who verifies it and what follows when the terms are breached.

Lee's formulation is best understood as a diplomatic opening rather than evidence of an agreement. The next question is whether Pyongyang sees a phased process as a route to security and relief, or as a slower path to the same demand for surrendering its strategic capability.
