If you watched the same game as I did I shouldn ' t have to <| sep |> The Romulans for example don ' t trust humans initially because of their alliance with their Vulcan cousins . I admit TNG left me with the opinion that the only really valid use for Romulans was target practice . I ' m willing to concede that that may be slightly prejudiced . Truthfully though , I always advocated a treaty with the Cardassians , as well . The only thing they really wanted was minerals . Cardassia Prime is apparently a giant swamp , without the base metals that you normally find if you dig down far enough , on more habitable planets . We should have found them a nicer M class planet than the one they grew up on , in exchange for them becoming housetrained . I also don ' t mean slavery by that , either . I mean them having a firm understanding that going on armed pub crawls to the planets of 9 th century equivalent civilisations is not acceptable . Unfortunately , some species go through the Space Viking phase . Humans mostly did it on Earth . It was probably briefly considered in space , but then the Romulans showed us why that wouldn ' t be a good idea . The Cardassians were not unsalvageable . They just needed their resource problems solved , and to have certain ground rules laid out for them , that ' s all .
