It is probably fair to say, then, that Mao was responsible for about 1.5 million deaths during the Cultural Revolution, another million for the other campaigns, and between 35 million and 45 million for the Great Leap Famine. Taking a middle number for the famine, 40 million, that’s about 42.5 million deaths.(sourcesource)
Quote from Ian Johnson in New York Review of Books post ‘Who Killed More: Hitler, Stalin, or Mao?’. I think that ‘Chairman Andrews’ has got a bit of a way to go to reach those numbers?
