Found this wonderful quote in a book I'm reading. It is from Krushchev, in the days after the Cuban Missile Crisis, "I'm not a czarist officer who has to kill himself if I fart at a masked ball. It's better to back down than to go to war."
Quoted in John Mueller, Atomic Obsession: Nuclear Alarmism from Hirosima to Al-Qaeda. New York: Oxford University Press, 2010, p. 40.
