If you were to read the books that were made after the end up deep space nine and TNG. They talk about the recovery and rebuilding efforts of the Federation after the Dominion war and after the Borg supercrisis in the destiny trilogy. In the books outsiders have started to notice the change in Starfleet. In fact one Breen commander says that back in the day Starfleet was little more than scientist who explored and then occasionally defended their homes. Then they can bring commander says that now Starfleet is now acting more like a military but is still an exploration agency. That’s the Federation believe that a explore first defend second starfleet cannot defend them anymore so they have to change it So what’s your opinion did the Dominion war change the way Starfleet operates or are they still the same explores they were before the war. I know it’s probably gonna be hard to answer this question since I doubt everybody has read the books. But you can see a little bit of it in Star Trek nemesis whenever Starfleet has battle groups.
