Politicians are infamous for failing to keep promises, and the great Oz is no different. When Dorothy's party returns after killing the Witch of the West, the Wizard keeps them waiting, then puts them off. By accident, the all-powerful Wizard is exposed and his true identity revealed. Far from a mighty magician, "Oz, the Terrible" is merely a "humbug," a wizened old man whose "power" is achieved through elaborate acts of deception. The Wizard is simply a manipulative politician who appears to the people in one form but works behind the scenes to achieve his true ends.
