Prakseologiczna teoria stosunków międzynarodowych

International relations are a form of human action so they should become the object of praxiology as a science oriented to efficiency. The traditional approach however must be changed. As it suggested in this article, human action is divided into three sections – cooperation, struggling and rivalry, which correspond to three types of theories. It should be added that cooperation is a positive-sum game, struggling – a negative-sum game and rivalry – a zero-sum game. The theory of international relations should be focused on the link between principles of cooperation and principles of struggling. This means that theory of foreign policy should be a theory of control in the zero-sum game system.International relations are a form of human action so they should become the object of praxiology as a science oriented to efficiency.
