The Confederacy of Sentient Beings was an alliance of extraterrestrial species. It had three qualifications for admitting a new species: 1) to develop controlled nuclear energy; 2) to begin to explore outer space, and 3) to begin to master their minds and control objects directly. The Confederacy revealed themselves weeks later, in a set of messages broadcast to Earth from somewhere around Uranus. Dr Strangeglove was worried what would happen when the Confederacy learned that humans hadn't developed psychokinesis.
