Germany attacked the Soviet Union in June, 1941. Woody Guthrie was very motivated to help the Soviet Union by convincing the US to join the war. Before this, the Communists worked to keep American out of the war.
My late wife’s Great Uncle grew up with Woody and went to the same high school.
At a family reunion someone asked him what he thought of Guthrie. He thought for just a few seconds and said. “He was just plain sorry”.
