CIA vs KGB. The Art of Espionage

Allen Dulles, the head of the CIA in the 1950s and 60s during the Cold War between the Soviet Union and the USA, knew better than anyone about the intricacies of the struggle between the KGB and the CIA and the methods used by the KGB on the political arena of the world, where two social systems collided in a duel - communism and capitalism. Under such circumstances, the intelligence organizations of both countries did everything possible to cause as much trouble as they could for each other. Naturally, therefore, the opinion of a direct participant in the "war of intelligence services" about the famous espionage operations will be interesting to everyone.
