This question will resolve as N/A if no nuclear weapon is detonated in Ukraine after October 3, 2022 and before January 1, 2023, as per the question Will a nuclear weapon be detonated in Ukraine in 2022? If such a detonation occurs, resolves YES if within one month, a NATO member state detonates any nuclear weapon offensively. Resolves NO otherwise.
Resolution details (mostly copied from Metaculus):
Offensively means neither detonations for testing purposes nor peaceful nuclear explosions will count towards question resolution, even if such detonations cause substantial damage.
Nuclear detonations here include deliberate, inadvertent, or accidental/unauthorised detonations.
Determination of whether a nuclear detonation was by NATO member state will be based on reliable media reporting.
I will use Metaculus decisions on https://www.metaculus.com/questions/2797/no-non-test-nuclear-detonations-by-2024-01-01/ and related questions to determine whether a nuclear weapon detonation counts as offensive.
