There is some debate whether the movie was propaganda, a debate I'm neutral in. But if it's established that this screenplay was based on Katie Dallam, then in my mind there's no way it wasn't propaganda, because they took an inspirational and dramatic story and purposefully twisted it into a whole different animal.
It was based on short stories by F.X. Otoole written some years ago. He has since died. Sorry no 'Hollyweird consipacy' here.

2000 is "some years ago," true. But it's fewer years ago than the incident described by Charles Colson, so he could be correct that the actual events suggested the fiction plot.
