Why would a military strike on June 21st retroactively decide a market's outcome for June 19th or 20th? That makes no sense; those earlier markets had a finite window for action.
If no military action happened on the 19th or 20th, the markets for those days resolved to 'No' because nothing then occurred, not because of a later event.
It's like trying to get a refund for a missed flight after you've already boarded another one; the opportunity to claim expired.
Time, like money, is a dwindling resource, and past deadlines don't change because something new just happened.
