Mass homicide on the scale of the Great Leap Forward was something that Mao prepared for. He told the 1958 party congress it should not fear but actively welcome people dying as a result of party policy. It was a common theme of his at the time. In Moscow in 1957 he said: “We are prepared to sacrifice 300 million Chinese for the victory of the world revolution.” On the prospect of another world war, he told the party in 1958: “Half the population wiped out—this happened quite a few times in Chinese history. It’s best if half the population is left, next best one-third.” Hence, Mao’s eventual career tally of 70 million deaths was actually much less than he anticipated.
