This book attempts to chronicle and analyze one of the first covert operations of the nascent CIA in the early years of the Cold War: the removal of Envar Hoxha and the communists from power in Albania. The theory was simple; break this tiny nation off from the satellite of Soviet influence early and decisively, and spur popular revolutions elsewhere.
It covers over ten years of this plan's machinations, delving into a lot of different things. These include the beginnings of the CIA, and the personalities behind it; the climate and thinking of that early agency, and its goals along with the US's stated public policy; the affairs of other nations trying similar ideas and with competing interests in Albania, including the UK, Greece, and Yugoslavia; the art of spycraft, including the difficulties of communicating with base; and the numerous competing concerns of the people in the Agency-backed "government in exile."
Spoiler alert: the plan failed, miserably, though not in a spectacular fashion--more in slow-motion. The book definitely did not fail, but didn't quite succeed either. It's confusing, because it tries to cover such breadth. The timelines get difficult to follow, because like a lot of books trying to look at a long-running event from different angles, it goes back over itself to present the story from a different side. It's easy to forget that you've already been introduced to someone, because the book itself seems to forget--occasionally, events are repeated as if they hadn't already been discussed; it looks like an editing problem.
The book also draws some conclusions. The last chapter in particular makes the case that this failed operation served as a pathfinder for other CIA operations, some of which were "successful" (in the short-term) such as Guatemala and Iran. But reading the endless details of failed air-drops of operatives and their mostly useless missions, and the constant in-fighting and pettiness of the exiled leaders, who appear more interested in positioning themselves against each other than in saving their homeland, seem to show that it all appeared like nothing more than an expensive, deadly folly that ultimately proved meaningless. Ironically, shortly after this failed operation, Hoxha's own paranoia lead him to disconnect Albania from the Soviet Union, and eventually completely isolate it from everyone, all on his own (though the book leaves open the possibility that the CIA might have had a hand in fueling his paranoia with false information). That the Soviet Union didn't collapse as a result shows just how futile the whole thing really was.
If you can wade thru the details, you can learn a lot of interesting names and events, so it's a good introduction to the cold war, and the dark world of spying and "plausible deniability" in regime change.
