if the rescue mission had succeeded UFP influence would have increased at the expense of the Tal Shiar, by destroying the space docks the Tal Shiar, slowed the admission of new member worlds into the UFP, harmed the UFP’s moral credibility, and made the Romulan Senate even more dependent on the Tal Shiar.
