War! The Klingons and the Federation are poised on the brink, and then war is declared. Kirk and Spock visit the planet Organia. Organia, inhabited by simple pastoral folk, lies on a tactical corridor likely to be important in the coming conflict. Whichever side controls the planet has a significant advantage. But the Organians are a perplexing people, apparently unconcerned by the threat of the Klingon occupation or even the deaths of others in their community. Finally, Kirk and the Klingon commander Kor learn why, and the reason will change Federation/Klingon relations for decades to come. Written by CommanderBalok

Captain James T. Kirk: What would you say the odds are on our getting out of here?
Mr. Spock: Difficult to be precise, Captain. I should say, approximately 7,824.7 to 1.

You are now subjects of the Klingon Empire (and you don't care)
10 May 2007 | by mstomasoSee all my reviews

The Enterprise crew are the first Star Fleet representatives to arrive on the planet Organia as hostilities break-out between the Federation and the Klingon Empire. Organia offers tactical advantages and is inhabited by a passive, non-progressive, agricultural, humanoid people.

John Colicos turns in a landmark performance as a Klingon colonial administrator who arrives a few minutes after Kirk and Spock, with a full military contingent (uninhibited by the Federation's Prime Directive). Colicos' Kor becomes the archetypal personality for Klingon military leaders until the Klingons are somewhat redefined in DS9. Kor establishes mercilessness as his model and begins executing Organians who do not offer complete and open cooperation. And the Organians don't care. They sit back, aloof - neither resisting nor cooperating, and frustrate both Kor and Kirk.

The episode offers a brilliant, somewhat nihilistic and humbling resolution - which you will have to see for yourself, and is one of the most satisfying of TOS. It's only negative point is the over-abundant and unnecessary 'witty banter' between Kirk and Spock as they plot against the Klingons - more subtly exploited in later Coon scripts.

Highly recommended.
