Invaders from earth

the long version

Ted Kennedy, advertising executive for the Ganymede Project, is made aware of a plan for genocide, for the murder of all the peaceful natives of Ganymede in furtherance of commerce...and it is his decision as to whether he collaborates with, facilitates this genocide or - by opposing it, by bringing the truth to the public - he risks not mere failure but utter destruction.Robert Silverberg's comment on his novel: ..."it involves a Madison Avenue hoax involving a nonexistent colony on Ganymede being worked up for political purposes, some sort of cynical disinformation campaign of the kind that was science fiction in l958 but is everyday news these days."Everyday news and, of course, the premise of the successful and frighteningly premonitory film, Wag the Dog.
