Final answer:
The photo with Russian children and a portrait of Stalin exemplifies the totalitarian trait of enforcing support for a leader. This is done through propaganda that idealizes Stalin as a paternal figure and promotes unquestioning loyalty and obedience among children.
Step-by-step explanation:
The photo of Russian children in front of a portrait of Josef Stalin surrounded by smiling children illustrates the characteristic of totalitarianism where the government enforces public displays of loyalty and obedience to its leader. In various propaganda posters, Stalin is depicted in a manner that creates an almost mythical and iconic figure to encourage unquestioning obedience and spiritual faith among children, filling the void left by the suppression of religion. These depictions show Stalin in a paternal role, symbolizing the idea that he is the father of all children in the USSR, who are shown as grateful, obedient, and indebted to Stalin for their supposedly happy childhoods.
