Will North Korea conduct a nuclear test on or before 31 March 2023?

North Korea’s recent flurry of missile launches, including an intercontinental ballistic missile (ICBM) launch on 18 November 2022, has raised expectations that it could soon test a nuclear device for the first time since 2017 (CBS). North Korea has finished all technical preparations for a new test in the underground tunnels at the Punggye-ri Nuclear Test site, which has been shuttered since 2018 (Reuters). Officials in the United States and South Korea have warned for months that Pyongyang is preparing for a nuclear test after a five-year suspension — a move that would signal North Korea speeding ahead with the development of advanced weapons capabilities (Al Jazeera).
Resolution Criteria: This question will be resolved using reputable news media reports (e.g., Reuters, NYTimes, AP, BBC). A nuclear test would involve the detonation of a nuclear device. Radiological devices (also known as "dirty bombs") will not be considered nuclear weapons (Mass.gov).
