Sir, I am perturbed at Alan Storkey’s “The Failed United States Political Witness” (comment: 18 March) wherein he implies it wrong to demonise Stalin and Communism. Nearly 100 million were massacred during the short ascendency of Communism in the Soviet Union and elsewhere (Courtois et al: The Black Book of Communism, English translation: 1999 Harvard). I am particularly concerned that he lauds the sacrifice of the Soviet troops under Stalin during the Second World War while passing by Stalin’s part in the 1939 Molotov-Ribbentrop pact with its secret protocol dividing up Europe between Soviet and German spheres. This led to the Soviet wars of aggression against Estonia, Latvia and Poland (including the Katyn massacre). If the Soviet Union had not switched sides and become one of the victors, it would have been impossible to cover up and pass over Stalin’s egregious war crimes.
