No, it's actually a decent book for being lib-brained. It explains the dynamics of power from a material basis and even makes the point that, structurally, a corporation resembles a dictatorship.

It obviously doesn't land on the right solutions (revolution) but it does lay out in black and white that "the support of the people" doesn't matter if you don't ensure the support of your direct followers by ensuring their interests are taken care of using your access to and control of material resources.

It correctly identifies the Machiavellian dynamics of political power and then refuses to do anything with that information. But it can be a good book for demonstrating to libs that, no, this shit does not run on vibes, but on blood, and "foreign aid" largely just ends up being payments to the bourgeoisie of third world nations to keep the grift going, though they misinterpret it as good intentions gone awry. It can be a stepping stone to radicalization. But only that.

I read the book. I don't remember if it talked about Stalin and Mao, but I do remember it gave a very unfavorable portrayal of Castro's rise to power and government.
