Interaction and Chaotic Behavior in International System

Various theories have been proposed to analyze behaviors in the international arena. Some theories, such as mainstream theories, are influenced by the linear approach of classical science, considering the international system as mechanical, closed, and far from interaction. Others, such as complex systems theory, considered the concept of nonlinear relationships and interaction used in the analysis of biological systems to explain the behavior of the international system and tried to explain human behavior as a biological system. Interaction is the main concept in explaining the behavior of natural and living systems that causes chaotic behaviors. Because the concept of interaction in human systems, as the highest example of biological systems due to the power of thinking, is a different concept. The purpose of this article is to introduce the interaction in the international system with features; Flow-creation and interpretation of information, purposefulness, sensitivity to the initial condition and impact and effectiveness. Studies show that due to the differences between human interaction and the interaction of other living organisms, Chaotic behaviors in the international system have characteristics; Simplicity in complexity, certainty in uncertainty, and order in disorder.
