CIA vs KGB. The Art of Espionage

Allen Dulles, the director of the CIA in the 1950s and 60s during the Cold War between the Soviet Union and the USA, knew better than anyone the nuances of the struggle between the KGB and the CIA and the methods used by the KGB on the political stage of the world, where two social systems - communism and capitalism - clashed in a duel. In such circumstances, the intelligence agencies of both countries did everything to cause as much trouble as possible for each other.
It is natural, therefore, that the opinion of a direct participant in the “war of intelligence agencies” about famous espionage operations will be of interest to everyone.
