To avoid the capture of the ship by the Klingons, Kirk had to destroy the Enterprise. Spock was saved and his mind reintegrated into his body.
2286 When an alien probe on the search for the extinct humpback whales threatened Earth, Kirk and his crew travelled to the past in a Klingon Bird of Prey.

A joined conspiracy of Klingon and Starfleet officers, however, tried to obstruct the peace plans by all means.
