Jews -Stalin ,Kruschev and Mao mass murderers

The Gulag Archipelago is Solzhenitsyn's masterwork, a vast canvas of camps, prisons, transit centres and secret police, of informers and spies and interrogators and also of heroism, a Stalinist anti-world at the heart of the Soviet Union where the key to survival lay not in hope but in despair. The work is based on the testimony of some two hundred survivors, and on the recollection of Solzhenitsyn's own eleven years in labour camps and exile. It is both a thoroughly researched document and a feat of literary and imaginative power.The three-volume book is a narrative relying on eyewitness testimony and primary research material, as well as the author's own experiences as a prisoner in a gulag labor camp. Written between 1958 and 1968, it was published in the West in 1973, thereafter circulating in samizdat (underground publication) form in the Soviet Union until its official publication in 1989.
