This paper examines the theoretical foundations of war and conflict in international relations, drawing on realist, behavioral, and rationalist frameworks. It explores Kenneth Waltz's critique of classical realism and his argument that anarchical systemic pressures, rather than human nature, drive states toward war. The paper also analyzes how behavioral factors — including misperceptions, incompatible goals, and third-party involvement — escalate crises, using the Cuban Missile Crisis as a key example. Finally, it considers the growing role of internal power struggles and mass mobilization as instruments of political change, arguing that understanding domestic dynamics is essential to interpreting modern international conflict.
The various theories of international relations have developed as reactions to significant advancements in war strategies, power struggles, and resource scarcity. As the world has diversified its means of conflict and resolution over the centuries, so too have theories of international relations evolved. To arrive at a generally accepted theory of war would require bringing all existing theories to the same table and combining them in a way that produces a unified framework. There are various types of theories relating to war, and all offer valuable tools for analyzing conflict — whether Marxist, behavioral, evolutionary, rationalist, or realist in orientation.
One of the key theorists in this field is Kenneth Waltz, whose influential book Man, the State, and War critiques classical realism in international relations. Waltz argued that the main cause of war is not human nature or the quest for domination, but rather the anarchical systemic pressures to which states are subject within the international system (Waltz, 2001).
As Jacoby suggests, behavioral types of analysis are equally important in determining the evolution of a war, a crisis, or a conflict. Crisis situations in international relations are often escalated and extended in time and space not only by individual decisions and perceptions, but also when the immediate conflict attracts the interest of parties that were not initially involved. Behavioral theories presented by Jacoby also address perceptions and, most importantly, misperceptions. Crises are not necessarily based on valid information or actual events, as these may be fabricated or imagined.
Jacoby introduces the concept of incompatible goals from the outset of his book, stating that "realistic conflicts are based on past occurrences that have led to the perception of incompatible goals" (Jacoby, 2008, p. 19). These goals, situated within the framework of a realistic conflict grounded in real threats, are typically opposed to one another. Unrealistic conflicts — arising from misperceptions in the decision-making chain — can also serve to advance one party's goals, either by manipulating the other party into a false understanding of a situation or by exploiting an accidental misperception.
