IntroductionNeo-Realism was the most appropriate political theory to explain the events of the Cold War. This article will explore the rise of neo-realism and its assimilation to the praxis of the Cold War. The main researcher that will interest me is Kenneth Waltz (considered the father of neo-realism). Before beginning my analysis, I would like to note that this article excludes the breakdown of offensive and defensive neo-realism as specific strands; I mainly focus on the theory as a whole. The period I will examine here is explicitly the Cold War. Neo-Realism The leading scholars of Neo-Realism are John Mearsheimer, Hans Morgenthau, and the aforementioned Kenneth Waltz. The latter developed a theory that ignores the human as a causal factor and maintains that it is the anarchic system of the international scene and the absence of a central authority to protect states from each other that brings them to the main concern : security. This motivates them to seek more power and distrust each other. He argues that a bipolar world with two major powers and smaller alliances is easier to manage. (Waltz, 1988) The emergence of this theory dates back to the start of the Cold War. (Walt, 1998) The rise of the communist USSR and USA, in a battle of ideology and power, brought researchers back to the drawing boards. A situation like the Cold War had never been witnessed before and therefore gave a new meaning to power politics. Nuclear concerns and the then recent recognition of their devastating consequences, constitute the main basis of the idea of ​​what would later become the idea of ​​balance of powers and nuclear parity. These are the main elements that led to the development of Neo-Realism.AnarchyPrimary Neo-realism assumes...... middle of article...... analysis carried out by him in order to explain the situation of the he era gives neo-realism the most credibility when it comes to comparing theory to actual events.
