I have just watched "The Way of the Warrior" (first episode of 4th season of Deep Space Nine) and I found one of Sisko's reactions weird.
He says to Dukat:
Then I'll be there to reason with them. I doubt the Klingons will fire on a Federation ship.
Just a few minutes (hours) after telling his own crew, in DS9's Ops, that:
(...) The Klingons have withdrawn from the Khitomer Accords. The peace treaty between the Federation and the Klingon Empire... has ended.
The reaction to Dukat seems to be the opposite of his reaction to the crew of DS9. What prevents the Klingons from firing based on these events?
Can anyone explain this to me? Is there anything, that I'm missing? Because, for me, this is a clear mistake in a script.
