"Directed by Frank Capra, produced by the United States Information & Education Division of the Army Services Forces in 1946, this authentic film proposes, "War with Germany ends in victory, victory leads to peace ... Sometimes ... Sometimes not."
An instructional video for the US forces in Germany 1946. It was the time of no fraternisation policy. Americans of German origin make up the largest ethnic group in the USA, so many of the US soldiers occupying Germany had German roots actually.
