It's understandable to connect events, but a military strike on June 21st wouldn't retroactively change what happened, or rather didn't happen, on June 19th and 20th.
Each day's prediction market would resolve based on its own specific timeframe, like how a grant application deadline means results are final for that period.
Perhaps the resolution for those earlier dates was already set because no action occurred then, rather than being triggered by a later event.
