Shaping national interests is of a strategic and political significance for a state. ln this process, economic, ideological, military, cultural and other variable and invariable factors intertwine. Their realization brings states into contacts with other states. When one or several interests of one state run counter to the interests and objectives of another state, conflicts arise. This makes the protection of interests so vital. States organize the protection of interests by means of a system of national security. National interests are values and objectives directed towards the development of a national community while national security is an activity organized for their protection. A rational and realistic definition of national interests as well as of the mechanisms of their protection are important elements of a state's and international community's stability.
