A member of the Communist Party Secretariat in Czechoslovakia, Jan Kozak, wrote this small book as a historical account of how the communists used "pressure from below" and "pressure from above" to take over Czechoslovakia, "and not a shot is fired". Was done by parliamentary (legislative) means. The tactics were those espoused by Antonio Gransci, head of Italian Communist Party circa 1914. This method is being aggressively pursued in the Unit States today, having started circa 1913 or earlier.
