Core Event: DPRK Leaders Reject International Denuclearization Demands and Justify Nuclear Expansion
On September 17, 2026, Vice Defence Minister Kim Kang Il told the Beijing Xiangshan Forum that a “growing U.S.–led military buildup” and an “expanding nuclear alliance” among the United States, South Korea and Japan justify Pyongyang’s decision to continue strengthening its nuclear deterrent. In the same week, Kim Yo-jong, sister of Kim Jong Un and director of the Workers’ Party’s General Affairs Department, issued a KCNA statement rejecting the International Atomic Energy Agency’s (IAEA) call for North Korea’s denuclearisation, calling the agency’s remarks “familiar silly talk” and asserting the DPRK’s nuclear status is “absolute and irreversible.” A DPRK Ministry of National Defence spokesperson warned that recent U.S.–South Korean weapons-of-mass-destruction (CWMD) talks could trigger the country’s nuclear-force policy law.
Background & Context
The 70th IAEA General Conference in Vienna raised concerns about North Korea’s expanding uranium-enrichment capacity and urged Pyongyang to abandon its nuclear programme in a “complete, verifiable and irreversible” manner. Earlier, on September 10, 2026, U.S. and South Korean defence officials met in Seoul to discuss joint CWMD response mechanisms, a meeting the DPRK described as an “open declaration of confrontation.” A recent Freedom Shield joint exercise demonstrated continued U.S.–South Korean military coordination in the region.

Data & Statistics
The IAEA Director General reported an expansion of North Korea’s uranium-enrichment capacity and continued operation of key nuclear facilities, though no specific quantitative figures were provided.
Official Statements & Responses
The DPRK asserted its nuclear status is “physically and legally permanent” and that any perceived escalation by the United States, South Korea or Japan warrants a “solid nuclear shield” and could justify invoking its 2022 nuclear-force policy law. The spokesperson framed the U.S.–South Korean CWMD meeting as a “brazen declaration of confrontation.”
U.S. officials described the CWMD talks as routine coordination to improve response capabilities. Stephen Biegun added that a future meeting between President Donald Trump and Kim Jong Un would not be surprising, especially after the upcoming APEC summit in China.
Why It Matters / Impact
The DPRK’s framing of its nuclear arsenal as an irreversible defensive necessity heightens diplomatic friction and complicates multilateral non-proliferation efforts. By linking U.S.–South Korean security cooperation to potential legal triggers for nuclear use, North Korea signals a willingness to expand its deterrent posture, raising the risk of miscalculation in an already volatile region.
Conflicting Reports & Gaps
No independent verification exists for the DPRK’s claim that the United States is conducting biological-weapon activities in Ukraine or at U.S. Forces Korea bases. The exact legal provisions the DPRK might invoke remain unspecified, leaving a gap in understanding how such a declaration would translate into concrete action.
