I know it was mentioned at the end of BOBW 2 that the fleet would be back up to full strength by one year. I think that's kind of absurd considering the losses at Wolf 359 but that aside, I think it was a missed opportunity to not have a recurring subplot that showed how the Federation was weaker for a while and had to tread carefully in the Alpha Quadrant, forging new alliances, appeasing enemies, overlooking provocations, etc. I know Next Gen rarely did continuing storylines except for character-based ones, but this would have been an interesting one, to show a weakened and traumatized UFP dealing with stuff for a little while.
