Full Review: I really wanted to like On Tyranny, since the subject matter is so important, but the author makes the concept of tyranny almost laughable via his gross misjudgment of contemporary events, which undermines the entire work.
It's a shame, because there are some real gems in this book. Consider the following: "We certainly face, as did the ancient Greeks, the problem of oligarchy - ever more threatening as globalization increases differences in wealth."
