Josef Stalin was a 20th century Human and dictator of the ancient Soviet Union nation-state on Earth. He led the Soviet people through the Second World War on the side of the Allies against Nazi Germany, and was a rather controversial figure.
Shortly after Stalin's death in 1953, New York City publisher Douglas Pabst quipped that writer Herbert Rossoff had been angry ever since Stalin's death. Interpreting this remark as his being called a communist (or "red"), Rossoff reacted angrily to the insult. The exchange was part of Benjamin Sisko's vision as writer Benny Russell.
