Operation Barbarossa was a turning point for success of war+public opinion. Poor German tactics+planning led to Germans losing faith in govt. The defeat at Battle of Stalingrad in 1942 signified this would not be a quick war as the Germans hoped for. By this point, all areas of society felt impact of war. Rationing, shortages of resources, high levels of casualties+aerial bombings angered German public. Despite a Nazi propaganda campaign in 1943, an increased number of Germans began to oppose the regime.
