The U.S. vs. John Lennon is a documentary released in 2006 which depicts the movement of John Lennon from his musical career as a Beatle to one of social activist protesting the Viet Nam war and advocating for peace.
John had a great vision, an authentic life, and made a great contribution to the world both musically and prophetically. John was harassed by the F.B.I., and President Nixon and his administration who were so threatened by his anti-war activities that they wanted him deported from the United States. The parallels between the 70s and this first decade of the 21st century are striking. This documentary is well worth watching and I highly recommend it.
