Structural Realism in International Relations Explained
This paper provides an introductory overview of structural realism, also known as neorealism, drawing primarily on Kenneth Waltz's foundational contributions to the theory. The paper examines how structural realists understand power as the central force governing international relations, explores the distinction between defensive and offensive realist positions, and explains how concepts such as national interest, self-preservation, and anarchy drive state behavior. The discussion also addresses how states use international alliances, military force, and economic strength to acquire or maintain power, and why world peace is considered an unrealistic aspiration within this theoretical framework.

What makes this paper effective
- The paper grounds its claims directly in Waltz's text, citing specific page references throughout to support each theoretical point.
- It progresses logically from defining the theory to explaining its components — structure, power, interest, and morality — in a coherent sequence.
- The contrast between defensive and offensive realist positions adds nuance and demonstrates awareness of internal debates within the theory.
Key academic technique demonstrated
The paper demonstrates sustained engagement with a primary theoretical source. Rather than merely summarizing Waltz in passing, it returns to the text repeatedly to anchor each new claim, which is an important skill in political science and international relations writing. This approach shows the reader how the source's logic supports each element of the theoretical framework being described.
Structure breakdown
The paper opens with a definition of structural realism and its core premises, then moves into the debate between defensive and offensive realists. Subsequent sections address how governmental authority and international disputes arise from power competition, how national interest functions within the realist framework, and finally how power interacts with morality and state psychology. A Works Cited section closes the paper.
Introduction to Structural Realism
Neorealism, also known as structural realism, is a theory associated with realist perspectives in international relations. According to this perspective, all nations and all departments within national governments are competing with one another for power. In this contest for dominance, the various factions compete to gain power, particularly if doing so comes at the expense of other groups. Structural realists believe that society as a whole has a structure which may not be immediately discernible but is nonetheless an undeniable truth. The guiding principle behind this school of political thought is that it is power alone which regulates and dictates international relationships. The quest for power, and the desire to maintain the level of power a nation state already holds, directly shapes the decisions made by that government's leaders (Waltz 1987, p. 75).
The various groups competing for power have no choice but to engage in these political disagreements, because if they do not, they will not survive (p. 85). Rather, they will be absorbed into the government or brought under the leadership of the dominant group. As Waltz (1987) writes, "The survival motive is taken as the ground of action in a world where the security of states is not assured, rather than as a realistic description of the impulse that lies behind every act of state" (p. 85). A consequence is that there is always violence among competitors, and as long as groups must compete for power, the world will remain a dangerous place — for those involved and for innocent bystanders alike.
The Role of Structure and Power
Structure is the most important component of this school of thought (Waltz 1987, p. 73). Not all structural realists agree about the precise nature of these power exchanges. Defensive realists, for example, believe that the structural factors governing the struggle for power limit how much power individual states can acquire, and therefore also constrain how effectively a faction can defend itself against its enemies (p. 76). Offensive realists believe just the opposite: they hypothesize that the structures in place actively encourage the spread of domination and the accumulation of national power.
Governments, Authority, and International Disputes
All governments are, by the nature of their creation, organizations that possess power. According to Waltz (1987), "Political structure produces a similarity in process and performance so long as a structure endures" (p. 80). Governments hold power over their citizens, and based on their economic position and ability to persuade allies, various nations hold more power than others. International relationships add to the strength of a country and its leaders (p. 100). Without power over the citizenry, a government cannot maintain authority, and both the government and, most likely, the entire nation will fall into chaos and anarchy.
International disputes begin when one political group determines that it does not hold sufficient power and that the only way to satisfy that need is through the acquisition of additional territory (p. 120). This necessarily involves becoming the ruling power over lands that previously belonged to another nation. Since the only way to gain more power is for an opposing group to have less, other nations are compelled to build up their own armed forces — even if they have no aggressive ambitions — because they must be willing to defend their power with violence if necessary (p. 121).
