Quite so. This is from "United":
T'Pol: "Minister T'Pau is dispatching 23 vessels."
Archer: "That's all?"
T'Pol: "The High Command has been disbanded. Many of our ships no longer have full crew compliments."
Archer: "T'Pau could have picked a better time to clean house."
So, not necessarily funding cutbacks, but rather good old-fashioned purges.
The ships would still be there, waiting for new and politically palatable crews. So, in the medium and long term, the unavailability of ships probably wouldn't dictate T'Pau's politics. Rather, T'Pau's politics would be the reason for Vulcans not using the ships imperialistically any more.
