According to the Atlantic, the US really never had race problems: it was an invention of Soviet propaganda

"Neither is playing on racial tensions inside the United States a new Russian tactic. In fact, it predates even the Cold War. In 1932, for instance, Dmitri Moor, the Soviet Union’s most famous propaganda poster artist, created a poster that cried, “Freedom to the prisoners of Scottsboro!” It was a reference to the Scottsboro Boys, nine black teenagers who were falsely accused of raping two white women in Alabama, and then repeatedly—wrongly—convicted by all-white Southern juries. The case became a symbol of the injustices of the Jim Crow South, and the young Soviet state milked it for all the propagandistic value it could." Was the KKK inspired by Lenin?
