Communism between the hammer and the anvil. **Riondel Bruno** (2020). The dreadful truth, communism a century of tragedies and accomplices. 2ditions L’Artlleur. 790 p. Communism was never an ideal of progress and its monstrous crimes were not the fruit of an unfortunate drift. This is the demonstration made here by **Bruno Riondel**, a century after the birth of the Leninist International. Destroying the traditional cultural superstructure of societies by eliminating millions of people has always been a prerequisite for the implementation of Marxist-Leninist revolutions. Everywhere, these allowed violent minorities to exercise complete control over terrorized populations. **Bruno Riondel** demonstrates that communism had premeditated each of its acts, including mass crimes. It also shows that the communist fight always took place on a double level, exoteric, with destruction of the masses, and esoteric, for the initiated, the communist parties of the whole world having had, like the PCF, a double structure: a committed party that everyone knew, and its hidden side, controlled behind the scenes by the men of the Soviet International. To destabilize internal societies, communism used social struggles, using moral relativism and tactical lies, with the help of many intellectuals fascinated by its strength or simply opportunists. The author believes that communism is not dead. Its networks hidden under the masks of progressivism have preserved in particular, the capacity to stifle the scandal of the death of the tens of millions of innocent people sacrificed on the altar of the so-called proletarian revolution.
