Ah yes, that Mao one is the only other thing of Zizek's I've read. I believe this book (from looking at the subjects covered in the index and the blurb alone) is in some respects a greatly expanded version of that; mainly in the sense that it is highly critical of modern anti-capitalists who complain about the economic injustices of globalisation without linking it to a wider emancipatory struggle a la Lenin, or even a la Mao. In fact, they adopt a posturing and shallow anti-imperialism (or even more simplistically anti-Americanism, e.g. Chavez) but are actually simply hoping for a slightly more progressive rearrangement of capitalism itself.
Yeah, the Lenin thing is quite uncomfortable for more orthodox Marxists, because it prevents them from being able to explain away the USSR with fairly simple lines; "oh, Lenin did it the wrong time" etc.
Some of the stuff written by and about the revolutionaries sometimes seems pretty irrelevant now, I guess. Like a lot of the stuff about disciplined vanguard parties etc. in Lenin. Does it really have much relevance outside its original context? But it's still really fascinating and important IMO to study those movements and the truth of them. History and Revolution by Haynes and Wolfreys was a good collection of essays which talked about the conservative interpretations of revolutionary episodes in the past. Particularly the French one; it's commonly presented as being the bloodthirsty workers that caused all the violence and ruined a good civilised bourgeois liberal political transition. Whereas, this book argues that the radical left of the French revolution was the progressive side, abolishing slavery and empire, which was ultimately betrayed and those things reinstated when the liberals got back in charge with Napolean etc.
Another cool book on the French Revolution is "Vive la Revolution" by Mark Steel- who is a British socialist comedian. It's meant to be funny, but is also worth reading as a social history. You can hear him giving his lecture on it here. Pretty good but some references to brit politicians non-brits might not get.
