To wring further use out of the word, even Dukat manages to be slightly "pleasant" in this one. The firework "celebration" is actually a favourite moment of mine. "Well done, Bajorans/Benjamin. Here's a little firework display to applaud you".
It manages to be almost genuine as a political (and personal) olive branch, a friendly gesture between neighbours, while also allowing Cardassia politically and Dukat personally to maintain a slightly smug "upper hand" despite the potential embarrassment. Well played, Dukat, and well played, writers.
