"The needs of the many, outweigh the needs of the few." We don't know the situation of the universe entirely, but Utopia Plantia was destroyed and an entire fleet with it, specifically designed for purposes of saving the Romulans. Why is it hard to believe that Starfleet don't have the resources to put into reconstruction of their main shipyards ON TOP OF building a fleet that was already difficult to build? Nor the political will or capital. We've seen throughout series that the Federation and Starfleet is full of "bad guys" who think they're doing good, you don't think in the Federation council there are 10 Norah Satie's screaming about the Romulans being their historic enemy? I think if it wasn't for the Enterprise crew in Star Trek 6, they may not have helped the Klingons either. Think of the premise of Picard as a version of events where those bad guys got their way for once, there was no Picard or hero ship to come along and save the day.
