Answer No. The KKK was organized in the Southern US after the Civil War. You almost can say it was inspired by the Rebels soldiers. Modern KKK organizations use the Rebel flag and the Nazi flag as their rallying flag. However, there is a separate organization that honors the memory of Hitler and the Nazis by promoting hatred of blacks. Please NOTE THE STUDY OF WW2 IS NOT A STUDY OF THESE HATE ORGANIZATIONS.
