This song is obviously a nuclear apocalypse, and although I'm sure "green valleys" refers to some sort of last outpost of humanity, Green Valley is not only a town very near Tucson, but there was also once a missile silo there which is now the Titan Missile Museum. I don't know whether or not there's a connection.
