The military strikes on June 21st can't retroactively change what did or didn't happen on the 19th and 20th; that's just a waste of analytical focus. Markets settle based on real-time events, not future ones, or we'd be constantly draining our already finite attention. If nothing happened on June 19th or 20th, the markets closing with a 'No' simply means no action took place then, like when a stock prediction for Tuesday resolves 'No' because the news didn't drop till Wednesday.
