Au contraire, Candidate_23, I do think Pianocraft is right. It is true that Bowie was fascinated by fascism, but if you have read 1984, it gives the album an entire different feeling. I for one in fact regret reading 1984 in a way, since now I cannot listen to Diamond Dogs without getting an extremely bad feeling.
And are you sure you mean Rubber Band as a war-related song. I haven't listened to the song for a while, but I don't remember it to be a war-related song.
