One of the best non-fiction books I have ever read. Extremely well supported and with a dose of irreverent humor. She clearly shows that McCarthyism is a myth, Hiss and the Rosenbergs were guilty, and liberal incompetence gave us the the Cold War, the Korean War, the Cuban Missile Crisis, the Vietnam War, and the fall of the Shah. Further, FDR and Truman looked the other way after being told that Soviet spies were working for them. Again, this book was extremely well supported and a fascinating read.
