Pike being kept out of the Klingon War retroactively makes Star Trek: Insurrection make sense. Back in 1998, I was wondering "Why aren't they making this about the Dominion War?" At the time, I thought it would tonally fit as a follow up to First Contact. Yes, I know the real reason why: those who hadn't seen DS9 wouldn't have known who the Dominion are (even though they could've reintroduced them for the movie audience), but that's not where I'm going with this. So continuing along... If Cornwell didn't want someone as good-natured as Pike in the Klingon War, probably wondering if he'd be able to do what it takes to get his hands dirty, then I can see someone like Ross not wanting Picard, who'd be even worse, involved in the Dominion War. It gives an added wrinkle to Star Trek: First Contact too. Maybe there was more to it than just not wanting Picard involved because he was previously assimilated. Maybe, after "I, Borg", they realized that Picard will always do the moral thing no matter what, even at the cost of survival. During war, Starfleet seems to favor captains like Lorca and Sisko instead of Pike and Picard. Then, when they're at peace, Pike and Picard become their favorites again. Captain Georgiou, from what little we saw, seems more like Janeway. She straddles the line between idealism and pragmatism. She could probably command well in both environments.
