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.
