Navarro Has Written a J'Accuse for Our Time, a Bare-Knuckled Indictment of an Evil System
Format: Hardcover
Peter Navarro has written an exceptional book that should be required reading for those who seek to understand the abuses of the Biden presidency. The book is a poignant love story, an account of great sacrifice, and an illustration of the true totalitarian nature of the Left. It is a J'Accuse for our time. Like Zola's work, it is a bare-knuckled indictment of an evil system. Unlike Zola, this system conspired not against one man, but against the President and many others--in fact, well more than half the country. Navarro's account is a contemporary reminder of the abuses Arendt and Solzhenitsyn identified regarding not only the banality, capriciousness, and brutal incompetence of tyranny, but that one does not realize when it starts how horrific it will become. If the Left is not stopped, what they did to Navarro will segue to even greater abuses against more and more people. I Went to Prison So You Won't Have To is a warning to all Americans of what is at stake and hence is a book that Americans must read.

Find Out Who Was the Legal Secretary
Format: Hardcover
I ordered this book after watching Nuremberg with Michael Shannon and Russell Crowe because I wanted to find out who was the woman accompanying Justice Jackson to Germany. Yes, that was not his wife, it was his legal secretary, Elsie Douglas. This book is the only source I could find that goes into any detail about their relationship. What it provides is nowhere near salacious, because it is evident that Jackson took his secrets to the grave. What details it does provide about the evident love triangle that existed in Jackson's life for many years is quite sufficient to explain the events of Nuremberg.

Well written. Factual sloppiness.
Format: Hardcover
Good insight into Jackson’s approach to the law. Thoroughly researched. Well written. However, Professor White made two egregious factual errors, both of which are an indication of sloppiness on his part, as well as that of his editors and peer reviewers. First, he refers to the World War 2 Chief of Naval Operations as the Secretary of the Navy. Second he states that Los Alamos National Laboratory is in California.
