The book was promoted as a tell-all about how Trump is not competent to be President (obvious to me on a daily basis without this book).
I read it thinking it might contain enough substance to convince Trump supporters to vote against him. However, it's all about another self-congratulatory, self- serving politician promoting his own agenda.
It's extremely boring, most of the book is about how much more Bolton knows and cares about U.S. foreign policy than any other government official, past or present.
