It was hoped that the damage done would be both material and psychological. Material damage was to be the destruction of specific targets with ensuing confusion and retardation of production. The psychological results, it was hoped, would be the recalling of combat equipment from other theaters for home defense thus effecting relief in those theaters, the development of a fear complex in Japan, improved relationships with our Allies, and a favorable reaction on the American people.
