This one was a slog to finish. If you ever wondered how to make one of the most interesting and complex characters ever to be President boring, this is your textbook. Dallek misunderstands Nixon and paints him as entirely one-dimensional. The book itself is repetitive and filled with facts that don't add up to any kind of narrative.
Dallek's style also irritated me. He alternated between calling Kissinger "Kissinger" and "Henry" and jumped in often with editorial assertions that weren't backed up by evidence.
