The State Security Committee of the USSR rightfully belonged to the strongest intelligence services in the world. Based on archival documents, this book not only introduces readers to the history of the creation and activities of the KGB, but also to the secrets of the “Third World War” - the Cold War between the Commonwealth of Socialist States and NATO bloc. She will talk about how the KGB fought terrorism. What he informed N.S. Khrushcheva, L.I. Brezhnev, Yu.V. Andropova, M.S. Gorbachev. How the United States fought the “evil empire.” What contributed to the collapse of the Soviet Union. How relevant today are the words of the legendary Spartan ruler Lycurgus: “The state exists, protected by the personal participation of everyone!”? The author expresses the hope that this book will allow readers to discover more deeply some pages of the recent history of our Motherland.
