 When three of the Doolittle Raiders were executed, it evoked a passion for revenge in America, and the image of the "Japanese ape" became common in film and cartoons.The film "The Purple Heart" dramatized their story, with an airman giving a concluding speech that he now knew that he had understood the Japanese less than he had thought, and that they did not understand Americans if they thought this would frighten them.The diary of a dead Japanese soldier, which contained an entry coolly recounting the execution of a downed airman, was given considerable play as a demonstration of the true nature of the enemy.
