Only Nixon could go to China (Star Trek)

On the planet Earth, the senior crew of the USS Enterprise-A assembles for a meeting at Starfleet Command. The Commander in chief of Starfleet opens the meeting saying that the Klingon Empire has fifty years of life left in it. The C in C then turns the meeting over to Spock, who's been acting as a Federation Special Envoy, announces that two months previously an explosion on the Klingon moon Praxis has polluted the planet's ozone and that the Klingon Homeworld has only fifty years of life left without diverting resources from its military expenditures. Spock, at the behest of the Vulcan ambassador Sarek, has opened a dialog with Gorkon, the Klingon Chancellor, who wants to end all hostilities and dismantle all bases in and around the Neutral Zone. Admiral Cartwright objects, saying the Klingons must not be offered safe haven in Federation space. He declares that the Klingons would become the "alien trash of the galaxy", which brings a look of disbelief from McCoy. Cartwright suggests using military force so they can dictate terms from a far superior position. Captain Kirk, while not agreeing with the hard line tactics outlined by Cartwright, agrees that giving the Klingons free reign in Federation space is a "terrifying idea". Spock says they must act now to support the Gorkon initiative before more conservative elements can seize control of the Empire and try to fight to the death. Spock has volunteered the Enterprise and its crew to welcome Gorkon and his aides aboard and escort their ship to a peace meeting on Earth. Kirk protests that he is hardly the man for the job but is overruled and commanded to extend full diplomatic courtesy. At that point, Kirk is left alone with Spock, who reminds him of an old Vulcan proverb that "only Nixon could go to China." Kirk is angry that Spock would volunteer the Enterprise without consulting him. Spock states that his father, though Kirk knows that Spock's father is the Vulcan ambassador, to open the negotiations. Kirk is furious at Spock for having to treat the Klingon "animals" like honored guests after what they did to his son David; Spock knows how he feels about the Klingons, but says "they are dying". Kirk snaps, "Let them die!" Upon Spock's somewhat startled reaction, Kirk asks Spock if he has realized that the Enterprise crew is due to stand down in three months time, saying that they have all done "our bit for king and country" and Kirk says that Spock should have trusted him.
