UNIDIR's policy brief by Wilfred Wan explores the role de facto nuclear weapon states that remain outside of the Treaty on the Non-Proliferation of Nuclear Weapons could play in conversations on nuclear risk reduction. ONN's report on Nuclear Risk Reduction Approach for the Korean Peninsula was cited in relation to the author's observations about the possibility of an unauthorized use of nuclear weapons in the DPRK, which ONN named as a potential risk factor for crisis escalation on the Korean Peninsula.
