20 years ago, Soviet propaganda, which praised the "clean hands" and "hot hearts" of the Chekists, was replaced by anti-Soviet myths about the "bloody gabn." It was with the demonization of the KGB that the collapse of the Soviet state began. And until now, curses against the state security agencies remain the main trump card in the ideological war against our country. The new book of the famous historian refutes the most common, most rabid and slanderous fabrications about the domestic special services, showing the true contribution of the Chekists to the creation of the USSR, strengthening its defense capability, the development of the economy, science, culture, in defense of the rights of ordinary Soviet people and the Soviet way of life.
