meet Weyoun and Dukat to provided them with Federation secrets making Dominion invasion in Aphla Quadrand possible, quick and successful to the Dominion. This idea is prevented by Bashir and Odo.
Why this so extremely obvious (at least to me) opportunity wasn't exploited by Federation?
Episode ends with Odo saying to surprised Weyoun and Dukat that "they" will not come. Why didn't Federation use this situation to feed both enemy leaders with false information? In other words, why a sabotage or diversion was not used in this situation?
Is there any reasonable explanation, why Federation failed to make use of such a good opportunity?
