I'm watching TNG for the first time all the way through on Blu-Ray and last night I got to the episode I, Borg (a great episode, btw) and I started thinking. If we ignore the Enterprise episode Regeneration and the movie First Contact, which are humanity's earliest encounters with the Borg, and rely solely on the incident of the Enterprise-B picking up some El Aurian survivors, shouldn't Starfleet have been asking some questions? For one, it doesn't even seem like the basic questions of "Who destroyed your homeworld?" were asked to the El Aurian refugees, or else Picard and the Enterprise-D crew wouldn't have been so puzzled at their first encounter with the Borg in Q Who? In fact, when Guinan comes up to the bridge suggesting they turn back now gives the impression this is the first time any Starfleet representative was made aware that the El Aurians knew who the Borg were. And, if we take the Voyager episode The Raven into consideration, the Hansens were trying to convince Starfleet that the Borg existed, much to Starfleet's hesitation. And this is only twenty years or so before Voyager. So what did Starfleet do for the fifty years from the Enterprise-B incident to launching the Raven? Did they just not care that there was a race out there that was scooping up colonies or destroying whole worlds? Did the top Starfleet brass just sweep the whole thing under the rug? Or did they just not ask any questions? Maybe a sort of "Well if we ignore the problem, maybe it'll go away" scenario? What say you?
