Highly recommend: Killing Hope by William Blum, it dissects the history of the many authoritarian regimes the U.S. supported since WWII, coups the U.S. engineered, the revolutions it strangled in their infancy, governments it systematically destabilized, and the popular movements it crushed (often under the veneer of “stability” or “containment”).

If you're going to argue that the US support Chiang Kai-shek why not add in Stalin as well?
