I was about nine years old the last time I saw this film. I am in my late 50's now. It was shown in elementary schools to foster patriotism during the 1950's. I cannot comment on the film itself or its qualities as too many years have passed.
I can say, however, that it is not factual. Wikipedia.org says this about the story that the film was based on: "The Man Without a Country was a short story published anonymously by Edward Everett Hale, in the Atlantic Monthly in 1863. Although the events of the novel were set in the early 1800s, the story was an allegory and implicitly referred to the upheaval of the American Civil War..." We were also shown films such as "Reefer Madness" about the same time. I would put this film in somewhat the same category. Its purpose is to present an agenda rather than to entertain. Certainly not a fault in itself, but see this as an editorial on celluloid.
