"Don't Be a Sucker" is as timely now as it was back in 1947:
Don't Be a Sucker! is a short educational film produced by the U.S. War Department in 1943 and re-released in 1947. The film depicts the rise of Nazism in Germany and warns Americans against repeating the mistakes of intolerance made in Nazi Germany. It emphasizes that Americans will lose their country if they let themselves be turned into "suckers" by the forces of fanaticism and hatred. The film was made to make the case for the desegregation of the United States armed forces by simply revealing the connection between prejudice and fascism.
This film is not propaganda. To the contrary, it teaches how to recognize and reject propaganda, as was used by the Nazis to promote to bigotry and intimidation. It shows how prejudice can be used to divide the population to gain power. Far more significantly, it then shows how such tactics can be defanged by friendly persuasion; that protection of liberty is a unifying and practical way to live peacefully.
