Which of these inferences about the Roberts Report is best supported by the following passage (paragraphs 6-8)? The Western Defense Commander, Lieutenant General John L. DeWitt, who was responsible for the security of the Pacific coast, was influential in spreading the idea that the Japanese might be disloyal. Following the loss of Manila he said, “I have little confidence that the Japanese enemy aliens [Issei] are loyal. I have no confidence in the loyalty of the Nisei whatsoever.”

DeWitt’s distrust appeared to be confirmed in the Roberts Report, a government investigation of the bombing of Pearl Harbor. Issued at about the time Singapore fell to Japan in February, the report blamed the disaster on lack of military preparedness and on Japanese sabotage in Hawaii. It even suggested that Japanese farmers had planted their crops in the shape of arrows pointing to Pearl Harbor as the target.

Although the charge of Japanese sabotage on Hawaii was totally false, newspaper writers and radio broadcasters began warning of the danger of Japanese sabotage on the west coast. In Los Angeles, radio commentator John Hughes warned that “Ninety percent or more of American-born Japanese are primarily loyal to Japan.”
