This film was released in early 1942, just after the U.S. entered the Second World War. In 1941, before the Japanese surprise attack on Pearl Harbor, many people in the U.S. were "isolationists" and believed that the U.S. should not get involved in the wars overseas. In 1939 - 1941 there was a great national debate in this country over that issue. What does this movie have to do with that debate?
