Overall, I use a more military tone for TOS/TMP periods. I think Starfleet, in general, got more warm and fuzzy throughout the 24th C, but this turned about fast with the dominion War.
It's still most a captain thing, but that's one of teh big conflicts in the post DS9 game for us: the hawks that have come up through the DW vs. the doves -- the ones that are older Starfleet and think that defense is a big-mouthed diplomat.
"War is an ugly thing but not the ugliest of things; the decayed and degraded state of moral and patriotic feelings which thinks that nothing is worth war is much worse. A man who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
John Stuart Mill
