Soft power is a useful concept of political theory and sociology developed by J.S. Nye Jr. in 1990. However, this concept can be overly abstract and hence somewhat artificial. In particular, this concept has been criticized by other sources and points of view. This paper develops a more complex and systemic approach to the concept of soft power targeted to the field of international relations and aimed at being useful for decision-making. Such an approach could be used in other fields and provides alternative analytic possibilities.
