“There is no publication, in any language, that would even approach the thoroughness, reliability, and novelty of this monumental work .... For the first time in modern Hungarian history, and almost uniquely in the history of modern Europe, we are able to learn from original sources how exactly the decisions were taken that led first to the decline of the Stalinist system in Hungary, then to demonstrations for freedom and against the Soviet occupation .... [The 1956 Hungarian Revolution] will change forever our views of what happened in Hungary between 1953 and 1963.”
