You guys... Burnham has failed too. Much of the resurgence was because of Dukat's failure as a Cardassian; he got too entangled with Bajoran religion and the wormhole aliens, which ties into Sisko. If Sisko's demigod arc wasn't, then Dukat likely would've remained in power and the resurgence would never have happened. Damar was a patriot, not a leader. He wanted what was best for his people, Dukat wanted what was best for himself (and that was position behind a powerful empire/union). Had Dukat remained in power, I doubt there would've been a Breen involvement. Star fleet certainly wouldn't have retaken DS9, and Zyal wouldn't have lost her life. But it hasn't been just her. It's been Spock, Pike, Tilly, Saru, Philippa etc Michael has her support network too. The examples you've speculated could just as easily be the reasons they knew. We've only just been introduced to the notion. The explanations can come later. This wont the the last time we visit Nivar. An enjoyable scene indeed, one that I hope has a significant payoff.
