John Feffer in The Nation:
They were the “best and the brightest,” but on a spaceship, not planet Earth, and they exemplified the liberal optimism of their era. The original Star Trek, whose three-year TV run began in 1966, featured a talented, multiethnic crew. The indomitable Captain Kirk had the can-do sex appeal of a Kennedy; his chief adviser, the half-human, half-Vulcan Mr. Spock, offered the cool rationality of that “IBM machine with legs,” then–Secretary of Defense Robert McNamara. And the USS Enterprise, on a mission “to boldly go where no man has gone before,” pursued a seemingly benign anthropological interest in seeking out, engaging with, and trying to understand the native populations of a fascinating variety of distant worlds.
The “prime directive,” designed to govern the conduct of Kirk and his crew on their episodic journey, required non-interference in the workings of alien civilizations. This approach mirrored the evolving anti-war sympathies of series creator Gene Roddenberry and many of the show’s scriptwriters. The Vietnam War, which raged through the years of its initial run, was then demonstrating to more and more Americans the folly of trying to reengineer a society distant both geographically and culturally. The best and the brightest, on Earth as on the Enterprise, began to have second thoughts in the mid-1960s about such hubris.
Even as they deliberately linked violent terrestrial interventions with celestial ones, however, the makers of Star Trek never questioned the most basic premise of a series that would delight fans for decades, spawning endless TV and movie sequels. Might it not have been better for the universe as a whole if the Enterprise had never left Earth in the first place and if Earth hadn’t meddled in matters beyond its own solar system?
