Michael from Muckrock writes, "The FBI followed Ray Bradbury's career very closely, in part because an informant warned them that his writing was not enjoyable fantasy, but rather tantamount to psychological warfare."
"The general aim of these science fiction writers is to frighten the people into a state of paralysis or psychological incompetence bordering on hysteria," the informant warned. "Which would make it very possible to conduct a Third World War in which the American people would believe could not be won since their morale had seriously been destroyed."
