Weapons control and denuclearization in post-Kim North Korea must proceed in sequence—from immediate custodial control in the first hours, to phased and internationally anchored reduction within the first year, and ultimately to irreversible institutionalization within three years, securing a durable new security order.

With a coordinated plan in place, early stabilization can be achieved within the first 6–12 months after regime collapse, and then progressively institutionalized into a lasting security order—forming the foundation for political transition and economic reconstruction.
