The entire time I was reading this, I was thinking "Man, good thing I pulled this book on Chinese history so I could learn all about the Truman Administration." I felt like I was back in high school history, reading World History: The Americanized Version.
Not only that, the title personality--Mao--wasn't even the main "character" at all, even when the book DID feature China. We spent more time revolving around Chiang Kai-Shek and his wife than we ever did learning about Mao himself. Madame Chiang's legs were apparently extremely sexy and super important to the political climate of the 40s.
I am partially to blame for my lack of interest--I totally based my pick of this book on its cover, and only scanned the blurb. But the subtitle really should have been "Truman, Acheson, and the United States Interest in Chinese Communism." I suppose that wouldn't sell quite as many copies.
