Kim Yo Jong Rejects IAEA Denuclearization Calls, Declares North Korea's Nuclear Status 'Immutable'

Kim Yo Jong, the sister of North Korean leader Kim Jong Un, rejected the International Atomic Energy Agency's (IAEA) calls for denuclearization, calling them 'nonsense' and declaring the country's nuclear-armed status 'immutable' and 'irreversible.' Her remarks, delivered during the IAEA's 70th General Conference in Vienna, followed an annual safeguards report documenting the expansion of North Korea's nuclear facilities, including a new uranium enrichment facility at Yongbyon. Additionally, Kim Yo Jong and the North Korean Defense Ministry warned of potential nuclear and offensive military responses to recent US-led joint military exercises, such as the Pacific Vanguard 2026 drills, and US-South Korea defense talks on countering weapons of mass destruction.

// Background

North Korea expelled IAEA inspectors in 2009, forcing the agency to rely on satellite imagery and open-source intelligence to monitor its nuclear program. In 2022, North Korea passed a law declaring itself a nuclear-armed state, a status later enshrined in its constitution by Kim Jong Un. Tensions have remained high as North Korea continues to expand its nuclear facilities, including the Yongbyon complex, while the US and its regional allies conduct joint military drills to counter Pyongyang's weapons of mass destruction.
