Whether you like it or not, the Federation simply is not as militaristic as modern Western societies.
They don't have to be as militaristic as modern Western societies, they just need the level of militarism that the TOS Federation's Starfleet had.

You know things are bad when the guys who created a bioweapon to genocide an entire species in charge of an interstellar empire are the most competent, logical, and clearminded people working for the good guys
