The claims of genocide in Ukraine are unfounded Nazi propaganda originally popularized in the U.S. by anti-Semite and Nazi collaborator William Randolph Hearst (the founder of “yellow journalism”). The episode of Revolutionary Left Radio about Stalin completely debunks this myth, including the books by Applebaum and Conquest. It also ellucidates the purpose and context of the purges. Give it a listen.
By the way, I’m not suggesting the Soviet Union was perfect; I’m just saying the vast majority of the Western discourse on the USSR is based on propaganda, misinformation, omissions, bad-faith analyses, and fabrications.
