Diplomatic Implausibility (Star Trek The Next Generation, No 61)

200 YEARS AGO: The expanding Klingonâ„¢ Empire found a frozen world rich in deposits of the mineral topaline. They named the planet taD -- Klingon for "frozen" -- and they called the people jeghpu'wI' -- conquered.

FOUR YEARS AGO: The Klingon Empire invaded Cardassia, breaching the Khitomer Accords and causing a break with the Federation. On taD, depleted Klingon forces were overthrown in a small coup d'état, and the victorious rebels took advantage of the disruption to appeal for recognition from the Federation.

NOW: The Klingons have returned to taD and re-established their control. But the stubborn rebels insist on Federation recognition. A solution to the diplomatic impasse must be found, a task that falls to the Federation's new ambassador to the Klingon Empire -- Worf.

Worf thinks of himself as a fighter, not a negotiator, but the Federation disagrees. Now, for the sake of the Federation and the Empire, a Klingon warrior must weave a fragile peace out of a situation ripe for war!
