W Cleon Skousen,former FBI agent penned this informative book on the origins, appeal and rise of communism in the Soviet Union and the United States. This book was first published in 1958 with this revised edition put out in 1961. Skousen details the people and methods used to build and spread this collectivist ideology. Using the writings and interviews of the main proselytizers of this belief he chronologically details the rapid expansion of this pariah on the world. An interesting view from a man in a position most did not have and at the height of the cold war. Looking back we can see the amazing accuracy and truth of this book by how through our government and public [ indoctrination], education system,America has moved far to the left. And how we are collapsing morally,spiritually and economically like all socialist/communist nations through history.
