The article brings up a complicated problem of the measurement of national power. Many researchers have made numerous attempts to describe the issue in the theoretical view. Theoretical models which were drawn up can give reports of state powers which are not always too competitive. In practice, the task of setting the real measurement and comparing national powers is very complicated. In this area the most appropriate are models of F.C.German and J.S.Cline. Factors affecting the establishing of position of the state are various. For example the role of having the nuclear arsenal is still significant, but not as important as it was in the 1960s and 1970s. Of course the basic elements like geographical situation, relations with bordering states, military, economic, demographic component still exist. At present earlier determinants in form of: energetic resources, radioactive elements, petroleum, natural gas, demographic factors, even cultural attractiveness are gaining importance in positioning power. Position of power is not given forever and can change even as a result of random events.
