See the question and its resolution criteria on Metaculus: https://www.metaculus.com/questions/14899/1000-deaths-from-israeliran-conflict/

This question will resolve as Yes if, for the years 2023 and 2024 combined, the Uppsala Conflict Data Program (UCDP) reports 1,000 or more state-based conflict deaths for the Iran-Israel conflict (specifically, the category "state-based violence"). The 1,000 deaths need not occur in a single year. We will defer to UCDP's methodology in calculating conflict deaths.

If UCDP does not report data for 2023 and 2024, the question resolves as Ambiguous
