Answer: They promised the people military success.
Explanation:
Dictators build their rhetoric on an aggressive policy towards the alleged enemies of their state. Hitler, Stalin, and Mussolini used this concept during their reigns. Dictators create militant societies and promise the people that their goals can only be achieved if they are united in war times. In their speeches, they often use the rhetoric of war, and point out to their people that they are in danger from others.
