An important goal of anti-german propaganda was to

a. make germany surrender in order to end the war.
b. ask other countries to negotiate peace.
c. persuade germany to stop bombing ships.
d. convince countries to join the allied effort.

During the WWII the propaganda was indispensable to create in their citizens a support for the war and convince countries to join the Allied effort. In order to achieve this, they used a vast array of media, such as posters, advertising, radio, books, movies, and several other media. They depicted the war was an issue of good and evil.

To create the idea of anti-German they depicted Hitler, via caricature methods, ridiculing him. He and the German people were described as fools. Nazi German was portrayed as the worst enemy within the Axis. Germans were frequently stereotyped as evil in films and posters, although many barbarities were specifically ascribed to Nazis and Hitler specifically, rather than to the undifferentiated German people.
