"Most of what Mao tried to do backfired on him. The central organizing theme of the book, starting with chapter 7 and going through the very end, is that each time Mao tried a bold initiative, it had outcomes that must have surprised him—certainly [that] he did not welcome—and he repeatedly changed his tactics and ran into new problems. In the end—although this isn’t explicitly argued—I think you could probably draw the conclusion from the story that Mao lost his way in the end and ended up doing things that did enormous harm to China. He became so fixated on maintaining his vision that he lost sight of the damage that it was causing the country. What’s remarkable about him as a leader of a communist country is that he’s the only one who ever fomented rebellion against the state that he’d set up. If he had only wanted to get rid of officials who disagreed with him, he didn’t need to do that. I think that’s the thing that is really most remarkable about Mao as a leader. The other thing that I think people should walk away [with] after reading the book is that the period from 1949 through 1976 was really the core of the Chinese revolution. We tend to think of revolutions as being over when a new government takes power. But in China, that was just the beginning. China had not changed very much in 1949. The party had only controlled limited areas of the countryside. It ran no cities. It had this extremely rapid military conquest of China. The revolution in China was not one where ordinary people rose up under the leadership of guerrilla forces and took power in the cities. The Communist Party was able in the late 1940s to create a large modern army in Manchuria, and it basically rolled south and then west across China. It was a military conquest. So basically, the transformation of China that took place—the revolution—really began in 1949 and ’50, after this army took power."
