Posters, newspapers and songs were all used as propaganda. They promoted about the USA and as well as hatred towards the enemy. Germans were falsely depicted as cruel and Japanese people were dehumanised, sometimes depicted as rats.

The attack on Pearl Harbor presented an ideal propaganda tool. Posters showed the Japanese as cruel and treacherous because of the unannounced nature of their attack on the US fleet. Simple posters stating the message “Avenge Pearl Harbor” were created to win support for the war effort.

Through propaganda, the government hoped to encourage hatred of the USA’s enemies so that the American people would be prepared to contribute more to the war effort.

Anything that might obstruct the war effort was not published. Newspapers were and no reports of American defeats or deaths were allowed. Victories were celebrated.

Popular entertainment as propaganda

The USA used the film industry to help to mobilise public opinion in favour of the war effort. Films depicted the American army as brave and their enemies as cruel. Between 60 and 100 million people per week visited the cinema. They saw superheroes on the World War Two battlefields. Even the London fictional detective Sherlock Holmes was shown in Hollywood films investigating plots by Nazi spies. These Nazi plots also featured in weekly radio serials such as Dick Tracy.
