Following the events of "Empok Nor", would it not have made sense for the Federation to take control of Empok Nor and make it into a Federation starbase a la Deep Space Nine? Seems like a missed opportunity to me though I suppose that it's possible that they might not have had the time and/or resources to fix it up as it was discovered(?) near the start of the Dominion War but still.....Were there any official reasons given anywhere why they didn't? And there was not one but two more trips to the station during the season. I would speculate that there might have been a treaty stipulation between the Federation and Cardassians but any treaties with the Cardies were pretty much moot at that point anyway.........
