Not being in Phil Ochs discography doesn't necessarily mean he mightn't have written it, just that he never recorded it. Not that there's any reason to assume it was written by anybody whose name would ring a bell. Plenty of good songs written by people no one has ever heard of. Folk songs in general, for example.

Some clever use of language in there - for example the ambiguity of "They're learning to fight the American way".

That line "Who can deny how far we have come" sounds like the kind of line a politician would put in a speech.

And what sort of tune does it use?
