Rick Rubin said that what made Johnny Cash special was not that he was great but rather that he is great. He was a country star in the sixties and seventies with all the flaws that come with it. But in later years he kept on growing and became something bigger, flawed, aged, worn but seasoned. When I hear this song it reminds me of his shortcomings. Some folks will love him ironically and not be bothered by silly jingoistic songs like these, others will have to add it to the overall picture of of a complicated man.
