North Korea has slammed the door on any future denuclearization talks, calling the entire concept a relic of a bygone era. Kim Yo Jong, the influential sister of North Korean leader Kim Jong Un, declared on June 6 that US proposals for denuclearization amount to an “anachronistic dream,” labeling the regime’s decision to permanently retain its nuclear arsenal an “irreversible final conclusion.”
From negotiation to codification
In 2023, North Korea amended its constitution to formalize its nuclear weapons program as a permanent component of national defense. Then came February 2026. During the Ninth Party Congress, Kim Jong Un proclaimed that North Korea’s nuclear capabilities are “completely and absolutely irreversible.” In March 2026, another constitutional amendment went further still, mandating automatic nuclear retaliation in response to certain categories of attack.
Kim Jong Un has backed the rhetoric with action. Recent visits to nuclear facilities and announcements about expanding missile production capacity by 2.5 times suggest this isn’t just talk.
