yes, it's sarcasm, like "Maybe you wanna captain this mission yourself, Dax" meaning "don't tell me how to do my job" or "We Starship captains/people know what we're doing" Obviously it was sarcasm, otherwise we would think he was actually inviting her to join a starship, and it would have nothing to do with the topic at hand, and thus irrelevant to whether he offloaded the kids. If he did offload all the kids and civilians, it would be the very first time. It is clearly not procedure to do so. Koegh and the Oddysey for the purposes of this story, represent Picard and the Enterprise. This is for a number of reasons, like to show how scary the Dominion is by blowing up the famous hero ship with ease, or showing that "this ain't your TNG" Dax's line raises its own question. She says YOU WERE planning to... WEREN'T YOU? She says it this way, because Picard(and every other captain we know of in this situation) never ever does. Picard takes the children into every battle, or any sticky situation, The Neutral Zone, Romulans, Klingons, etc, every time. Even tracking down the Borg and creating a weapon to destroy an invading cube- kids come with. The other Galaxy class in "Contagion," kids/families come with and all die. Even Sisko's former starship went into battle with the civilians and kids aboard, and his wife and many others died. So you the big bad Galaxy class show up, with the experienced veteran and supremely confident(and possibly intended to come off as arrogant) Captain Koegh, who acts a lot like Picard, flies into the gamma quadrant with the attitude that "We'll give em a show of force. We're gonna try to get this straightened out." He has no idea what's coming; that his weapons and shields are useless. Edit: interesting side not- "Jem Hadar" aired just a couple of weeks after "All Good Things...," the hugely watched TNG finale seen by millions and millions of people. This was like the peak of Berman era Star Trek and the Enterprise D was the big star ship, Picard the star captain.
