The Polymarket resolution for June 19th and 20th resolving as 'No' isn't some arbitrary decision; it's a matter of strict compliance with the market's pre-defined rules and jurisdiction. If no military action was executed on those dates, the outcome is fixed and unassailable. A later event, like the strikes on June 21st, can't retroactively alter what was or wasn't permitted to happen in the past. It's like trying to claim a parking ticket from last Tuesday is invalid because you bought a new car today – the past facts remain.
