In Star Trek: Countdown comic series, Spock failed to create Red Matter on time (before the Romulan Empire got destroyed by a Hobus supernova).

Despite Nero's excuses, Spock was a good guy. He accepted Romulus as his home (according to comics). Even Picard and Data (captain of the USS Enterprise of that time) were supporting him to save the Romulan Empire. Why didn't he save the Romulan Empire by going back in time?

When it comes to time travel, Federation had experience with it. Kirk traveled in time by the slingshot effect a number of times (ST: Voyage Home and ST:TOS). Picard also returned back to future by reverse tachyon pulse (ST: First Contact). So, they were certainly be able to time travel.

The Temporal Prime Directive clearly states that Starfleet Personal of any kind has not to mess with the timeline.

Given that Spock was his whole life a follower and enforcer of rules and knows very well that altering the timeline can wreak havoc over everything, he most likely didn't even consider that possibility. Because when he goes back in time and saves Romulus, where does he draw the line?

    To save an entire race, I would happily violate the Temporal Prime Directive... Unfortunately, Sachin Shekhar wasn't there for that. :(

    Shouldn't the temporal agents who enforce the Temporal Prime Directive have intervened and prevented the Nerada from changing the timeline? Aug 31, 2012 at 19:15

  • He might've even been stopped by the "temporal police" if he tried to go back in time.
