On intelligence activities have been written numerous papers and books, in which most often are presented methods of data gathering but the essence and significance of these activities for each state are usually paid lesser attention. The intertexture and conflict of interests of states and alliances in the world demand that each state organizes its own two-way intelligence and counter-intelligence activities. In the process of discerning the advantages and weaknesses of forcing states (both hostile and friendly ones) intelligence activities rate exceptionally great significance. Those parts of the UN Charter that pertain to war, defense and security of states point indirectly to the necessity of organization and practicing of intelligence activities, and allow its state-members to undertake them. However, the states whose external policies are hegemonistic misuse systematically and in perfidious or even crude manners this possibility. Under the pretext and guise of organization and strengthening of own defense, such states very aggressively practice intelligence and subversive activities against states neighboring them and other states situated in their respective regions. The author presents comprehensively the flows of the intelligence activities effected within the frames of realization of domination in international relations on the part of certain states (their bearers - state, intelligence service; their phases - planning and organization; gathering, processing and utilization of intelligence data and information; principles of effectuation and possible consequences).
