It's not about genocide, it's about deterrence.
That's certainly how it was intended to be used in this episode, with Kirk obviously bluffing, but the point is, it still exists as an actual order, and implementing that order is effectively genocide.
There's really no sugarcoating that.
The bottom line, though, is that it's a hypothetical "doomsday option" that we never actually see implemented.
But that's also the thing, people don't usually make rules about hypothetical situations, we make em
after we need them, and only if the situation that requires them is likely to recur. Like the Talos general order, Pike first had to go to Talos for the higher ups to decide they want none of that, thank you very much, making it a rule to stay away.
So this kinda implies that at some point a starship encountered some planet, and regardless of what actually transpired there, when it came back to brass who were reviewing the decisions, they looked at the situation and decided that the best thing that captain could have done was just to annihilate everything. And not only that, but they thought such a situation might occur again so they made it a rule.
That just does not sound like Starfleet, not even a harsher 23rd century Starfleet,
That's more Terran Empire territory...
I agree that would be a good example of where it might actually be implemented in a practical manner
I don't. I haven't seen the episode in awhile, but weren't those creatures just controlling the population? To implement the order would mean killing every last human on the planet.
Imagine if a more trigger happy captain was there, he might not have bothered with trying to save everybody and just lit the place up. You know, a captain like, lets say...
Garth's crew mutinied to stop him from using it
That's all the evidence one needs for just how bad of an idea this is, had his crew been slightly more loyal and followed orders, the Federation would have an actual genocide on their hands, done completely by the book.
And Garth isn't the only insane captain we've seen on
Star Trek...
