8% chance. This question will resolve as YES if any nuclear weapon is detonated anywhere in the world after October 3, 2022 and before January 1, 2024. Otherwise NO. A test detonation would result in the question resolving as YES. A detonation would resolve YES regardless of whether it is deliberate, inadvertent, or accidental/unauthorised Detonation means nuclear explosion. If a nuclear weapon were launched/dropped/etc but the nuclear weapon did not detonate (due to malfunction, interception, etc), that would not count as detonation. If a conventional explosion occurs but no nuclear explosion (for example, a dirty bomb that distributes radioactive material with a conventional explosion), that does not count.
