Re: Organia and the Prime Directive
One think to remember is that if a local culture has already learned about extraterrestrial life before the Federation arrives, then that portion of the prime directive doesn't apply any longer. Considering that the presence of a civilian Vulcan trader on Organia was not seen as out of the ordinary, Starfleet wasn't concerned about revealing themselves. I assume a similar sequence of events on before "A Private Little War".
That's right! I feel like Rok when he realised he could override his programing. No matter how "primitive" the culture, if they had knowledge of aliens and other worlds then it doesn't fall under the Prime Directive!
