Star Trek episode "A Private Little War"

"A Private Little War"

Season 2, Episode 19.

Kirk says the planet they are on is the first planet Kirk ever did a planet survey on thirteen years ago. Starfleet says "NO INTERFERENCE" on this planet based on that survey.

Spock is shot by an old flint-lock rife. Bones says, "It's lucky his heart is where his liver should be or he'd be dead already."

The Klingons who have no such Prime Directive, help one group on the planet to create arms in order to disrupt the balance of power. There are a couple of inferences to Klingons breaking the treaty without mentioning the term "Organian."

We learn of the medical necessity of Vulcan-slapping to help them regain consciousness.

Bones and Kirk debate over Kirk's decision to give the other hill people guns in order "to equalize" the balance of power.

Kirk gets seduced by the witch doctor woman by some kind of plant fragrance. She's conniving; she only wants his phaser. She hits Kirk over the head with a rock and takes the phaser to the other side, then appears to get gang-raped. She is knifed to death by the rapists when they are trapped by Kirk and the hill people.

What I really want to know is what happened on this planet. Kirk requests 100 flint-locks be replicated, an order questioned by Scotty, then they just ask to be beamed up. What happened with the Klingons? With the whole planet? Was the Prime Directive violated? What did Starfleet do? On a larger scale for Star Trek: Could and would the Klingons and Romulans interfere with other "hands off" planets in order to gain more power and control?
