After World War II, the world split into two opposing camps. The world community found itself on the verge of a new war. The fate of all humanity in these years was decided by several states. Countries developed plans for nuclear attacks, drew up bombing maps, and conducted active reconnaissance and subversive activities. The world economy worked to build up nuclear potential. This period of history is usually called the Cold War. Who is to blame for the outbreak of the Cold War? Can we today give an objective assessment of the activities of politicians in the leading countries of the world? The author of the book describes in detail the events of that time, from which it clearly follows that official propaganda had nothing to do with reality.
