The book was reviewed by Matthew J. of Office of the Director of National Intelligence in Studies in Intelligence, who stated, "On balance, this is a useful and thought-provoking book on the trajectory of post-Soviet Russia and the continued influence of the KGB inside the Kremlin." Writing for The New York Times, Jennifer Szalai in her review questions that, "to read this book is to wonder whether a cynicism has embedded itself so deeply into the Anglo-American political classes that even the incriminating information it documents won’t make an actionable difference."
