Part and parcel to intelligence operations, the SD carefully tracked foreign opinion and criticism of Nazi policies, censoring when necessary and likewise publishing hostile political cartoons in the SS weekly magazine, Das Schwarze Korps.[50] An additional task assigned to the SD and the Gestapo was keeping tabs on the morale of the German population at large,[51] which meant they were charged to "carefully supervise the political health of the German ethnic body" and once any symptoms of "disease and germs" appeared, it was their job to "remove them by every appropriate means."[52] Regular reports—ranging from opinion polls, press dispatches, and information bulletins were established.
