Sisko refuses, and many Klingon ships fall victim to the upgraded tactical systems of the station.
Her embarrassment when the two run into Worf for the first time ("Nice hat.") is funny yet gratuitous.
Gowron greets Worf as his friend, but that is a mere lip service.
In TNG: "Sins of the Father" Worf accepted to be dishonored in order to avoid a civil war.
Regarding Worf's dilemma, I think we can all appreciate that he does not join Gowron's glorified quest.
But while we may look at it from a human/Federation viewpoint, as we would not want to be drawn into an unjust war, Worf's decision also has a very personal, a Klingon perspective.
