Why would anyone connect military strikes on June 21st to a "No" outcome for markets on June 19th and 20th? Historically, these prediction markets operate on strict timeframes for a reason.
If there was no military action on the 19th or 20th, the markets for those days properly resolved as "No"; a later event doesn't change what already did not happen.
It's like trying to claim a traffic fine from last week was cancelled because you got a parking ticket today; the events are separate and resolved independently.
