I wasn't claiming he was a fortune teller predicting the future, but rather that he might have been in with the young revolutionaries. There are lots of artists and entertainers today who are still calling for revolution. Maybe he thought he cleverly coded the message and that law enforcement would be too dumb to figure it out.
There is a major difference between now and then. Now, the American people will fight back. These revolutionaries had a pass during the 70’s. They’ll try, especially if Obama loses.
Dylan wrote basically one album worth of explicit “finger pointin’ songs”. After that he branched out into other things and being far more of a rock singer/songwriter rather than a folk singer.
His protest songs came very early in his career which is as much a product of his idolization of Woody Guthrie as any deeply held beliefs.
He has never gone to protests and joined in all the liberal causes. He was always more into music than political beliefs. His contemporaries from the time, who were into the protests and movements, said Dylan was (and presumably is) apolitical.
Is the song most likely about disaffected youth? Yes. Is it hiding some revolutionary call in its lyrics? Highly doubtful.
