The military strikes on June 21st didn't directly cause the 'No Outcome' resolution for the June 19th and 20th markets; those dates had their own finite windows for action.
If no military activity happened on those specific days, the markets would resolve 'No' anyway, regardless of later events.
It's like saying a job offer on Monday was caused by an interview on Friday; the interview was necessary, but the offer is a separate event.
Each day's market outcome is a closed account, not influenced by future strikes.
