The missiles falling on the Middle East carry more than explosives. They carry the accumulated weight of every international relations theory developed since the discipline's inception—and the empirical evidence suggests that most of these theories have just failed their most consequential test.
What is unfolding across the region is not merely another chapter in a centuries-old sectarian struggle or a routine escalation in the endless cycle of Middle Eastern violence. It is a living laboratory for international relations theory, a brutal empirical examination of the frameworks scholars have constructed to explain why states behave as they do. The results demand our attention not as abstract academic exercise but as the necessary precondition for understanding a conflict that threatens to reshape the global order.
Liberalism lies in critical condition. Realism has reasserted itself with a vengeance. Constructivism explains the irrational intensity. And Marxist world-systems theory offers the Global South its vocabulary of grievance. But none of these frameworks, deployed in isolation, captures the full pathology of what we are witnessing.
This essay moves beyond headlines and into the structural logic driving state behavior, engaging directly with the theorists who attempted to predict and explain the dynamics now playing out in real-time.
I. The Realist Foundation: Anarchy and Its Consequences
The first thing to understand about the Iran conflict is that it was structurally inevitable. Not in its timing, not in its specific triggers, but in its fundamental character as a security competition between states operating in an anarchic international system.
Realism, the oldest and most pessimistic school of international relations, begins with a simple premise that has proven remarkably durable. The international system is anarchic—there exists no global Leviathan, no supreme authority capable of enforcing agreements or guaranteeing security. States therefore exist in a condition of permanent self-help, where today's ally may be tomorrow's threat and where security is necessarily a zero-sum game.
The Security Dilemma in Operation
The concept of the security dilemma, first systematically theorized by John Herz in his 1950 article "Idealist Internationalism and the Security Dilemma," captures the tragic logic at the heart of the Iran conflict. Herz argued that the security dilemma emerges precisely from the anarchy of the international system, wherein "states strive to attain security by acquiring more and more power. This, in turn, renders the other states more insecure and compels them to prepare for the worst, resulting in the vicious circle of security competition and power accumulation" .
Watch this dynamic operate in real-time. Iran expands its influence through proxies in Yemen, Syria, Iraq, and Lebanon. It advances its missile program. It accumulates enriched uranium toward nuclear capability. From Tehran's perspective, this represents defense—an asymmetric shield against a region saturated with American bases and Israeli technological superiority.
But as Robert Jervis elaborated in his foundational 1978 article "Cooperation under the Security Dilemma," the dilemma exists precisely because "many of the means by which a state tries to increase its security decrease the security of others" . Israel and the United States do not interpret Iranian actions as defensive. They perceive a Shia crescent encircling them, a second-strike capability in the hands of a state whose leadership has called for Israel's destruction, an existential timer counting down toward nuclear armament.
The result is a spiral that neither side can unilaterally escape. Preemptive strikes follow. Scientists are assassinated. Facilities are bombed. Commanders are targeted. And Iran, seeing this, doubles down on the very programs and proxies that triggered the attacks.
Jervis, writing about the psychological dimensions of nuclear deterrence, offered a prescient warning that reads today as prophecy: "If war can come by a self-fulfilling prophecy, then the danger of war can build on itself; the reality is created by the participants' beliefs. The background mood can thus be crucial" . The background mood between Iran and the West has been deteriorating for decades, each cycle of action and reaction reinforcing the worst assumptions each side holds about the other.
Neither side is lying when they claim to act in self-defense. Both are telling the truth as they perceive it. And that is precisely what makes the security dilemma inescapable.
Waltz and the Nuclear Paradox
Perhaps no intervention in the theoretical debate surrounding Iran has proven more controversial—or more prescient—than that of Kenneth Waltz, the founder of neorealism. In his 2012 Foreign Affairs article provocatively titled "Why Iran Should Get the Bomb: Nuclear Balancing Would Mean Stability," Waltz divided the scholarly community into warring camps .
Waltz's argument was characteristically bold and counterintuitive. Drawing on the historical record of the Cold War, he contended that an Iranian nuclear bomb would not only fail to pose a security risk but would in fact be desirable, since it could serve as a practical deterrent against Israel modeled on the US-Soviet experience of mutually assured destruction. "History has shown that nuclear deterrence functions almost like a law in international relations," analysts have noted, "as there has never been a case where two nuclear powers have engaged in a full-scale war" .
The opposing school of thought, which has dominated Western policy, holds that Iran must be prevented at all costs from becoming a nuclear power, warning that such a development would provoke conflict with the potential to spill beyond the Middle East region. Israel's Begin Doctrine, articulated across multiple Israeli governments, explicitly commits to preventing any regional adversary from acquiring nuclear weapons, by military intervention if necessary.
The empirical record since Waltz published his article offers some support for his position. Scholars examining Iran's nuclear trajectory through a neorealist framework have concluded that "Kenneth Waltz's theory of deterrence is taken as a benchmark for creating stability in the Middle East. A nuclear Iran means a stable Middle East since Israel and Iran would become two nuclear neighbors like Pakistan and India; even conventional wars are halted with nuclear deterrence" .
Yet the counterargument has proven equally powerful. Waltz's critics contend that Iran's revolutionary ideology, its network of non-state proxies, and its regional ambitions render the Cold War analogy inapplicable. The Soviet Union, whatever its flaws, was a status quo power with a centralized command structure. Iran's decentralized network of militant allies, the argument runs, creates risks of escalation that a state-to-state deterrent relationship cannot contain.
The debate remains unresolved, but the theoretical stakes are clear: either Waltz was right, and the path to stability runs through Iranian nuclearization, or his critics are correct, and a nuclear Iran would trigger precisely the regional conflagration that current policy seeks to avoid.
Mearsheimer and Offensive Realism's Dark Prediction
John Mearsheimer, the University of Chicago political scientist whose theory of "offensive realism" has shaped a generation of scholarship, offers a still darker lens through which to view the conflict. In his seminal work The Tragedy of Great Power Politics (2001), Mearsheimer argued that great powers are not simply security-seekers but are compelled by the structure of the international system to pursue regional hegemony and to prevent the emergence of peer competitors.
The application of this framework to the Iran conflict yields disturbing conclusions. Recent remarks by Mearsheimer himself, given renewed attention following the deadly strike on an elementary school in Minab that killed 168 children and teachers, cut to the heart of the matter. "We are a remarkably cruel country," Mearsheimer said of the United States. "The level of slaughter and chaos we have caused across the world is unbelievable. U.S. sanctions from 1971 to 2021 have killed 38 million people, thirty-eight million people! We are using this enormous economic lever basically to keep people starving and suffering so they rise up against their governments—that is what we're doing in Iran. Given all this, it's very hard for me to talk about the United States as a decent country" .
From this perspective, the Minab massacre represents not a tragic accident or a deviation from American values but the logical endpoint of a system that prioritizes dominance over human life. Iranian observers have seized on Mearsheimer's confession as "not just a moral statement—it's strategic evidence that American realism has devolved into what they call 'suicidal barbarism.' They contend the Minab massacre represents the point where systemic cruelty reached a dead end" .
Whether one accepts Mearsheimer's characterization of American policy, his theoretical framework illuminates an uncomfortable truth: from an offensive realist perspective, the United States cannot tolerate an independent, powerful, and hostile Iran any more than it could tolerate a Soviet Union that refused to accept American hegemony. The conflict is not about specific policies or particular grievances. It is about the structural imperative of dominance in an anarchic system.
II. Structural Realism: System-Level Inevitability
If classical realism explains the motivations of individual states, neorealism—the structural theory developed by Kenneth Waltz—explains why those motivations are largely irrelevant. For Waltz, outcomes in international politics are determined less by the characteristics of particular states than by the distribution of capabilities across the international system.
The Middle East today exhibits precisely the structural conditions that Waltz identified as most war-prone. The region is multipolar, with multiple centers of power—Iran, Israel, Saudi Arabia, Turkey—competing for influence. No single state has achieved regional hegemony capable of enforcing order and suppressing conflict. The United States, once the undisputed external power, is in relative decline, its commitment to the region increasingly questioned by allies and adversaries alike.
Into this structural vacuum, Iran has risen. This is not because Iranian leaders are uniquely ambitious or ideologically driven, though they are both. It is because the structure of the system permits and even incentivizes such rise. As one analysis puts it, "Iran is no different from France or North Korea when it comes to possessing a nuclear bomb. It's all a matter of perception and who is looking at a nuclear Iran, be it an enemy like Israel, or some other country" .
The policy implications of this structural analysis are profound. If Waltz is correct that outcomes are determined by the distribution of capabilities rather than the character of regimes, then efforts to change the Iranian regime through external pressure are fundamentally misguided. Regime change would not alter Iran's structural position as a rising power in a multipolar region. A post-revolutionary Iran, even a democratic one, would still face the same security dilemmas, the same regional competitors, the same imperative to maximize its power relative to potential adversaries.
As one scholar has noted, "The fundamental objective [of the attack on Iran] was not the nuclear program itself but rather to change the regime of the Ayatollahs, since the Iran of the Pahlavi era was not Israel's mortal enemy" . Yet even if regime change succeeded—and the historical record suggests external intervention tends to strengthen rather than weaken domestic support for targeted regimes—the structural conditions that produce conflict would remain.
The implication is sobering: even with different leaders, even with a different regime, even with different ideological commitments, the conflict between a rising Iran and a declining American hegemony was structurally overdetermined. The only variables were timing and trigger.
III. The Liberal Reckoning: Institutions, Interdependence, and Their Limits
If realism explains why the war is happening, liberalism explains why diplomacy has proven so tragically incapable of stopping it.
Liberal international relations theory, in its various forms, rests on three pillars. First, international institutions can mitigate the effects of anarchy by creating transparency, building habits of cooperation, and facilitating the resolution of disputes. Second, economic interdependence raises the costs of conflict and creates constituencies for peace. Third, democratic governance pacifies foreign policy by subjecting it to popular accountability.
The Iran conflict has tested each of these propositions and found them severely wanting.
The Collapse of Institutional Architecture
The Joint Comprehensive Plan of Action, negotiated over years of intensive diplomacy and finalized in 2015, represented liberalism's signature achievement in the region. It was, to be sure, an imperfect agreement. It did not address Iran's missile program, its support for regional proxies, or its human rights record. But it did what institutions are supposed to do: it created verifiable constraints, established monitoring mechanisms, and provided a framework for ongoing diplomacy.
The Trump administration's unilateral withdrawal from the JCPOA in 2018 dealt a blow to the institutional architecture from which it has never recovered. The consequences have been precisely those that liberal theory predicts: uncertainty increased, verification mechanisms eroded, and the parties lost the habits of cooperation that the agreement had painstakingly built.
"Iran has since concluded that its only path to survival lies in skillfully balancing on the edge of nuclear armament, always remaining just 'a hair's breadth' away from the status of a nuclear power" . The Iranian calculation is rational given the history: an agreement was reached, the agreement was abandoned, and Iran was punished not for violating the agreement but for having negotiated it in the first place.
The Weaponization of Interdependence
Liberal theory also holds that economic interdependence makes war too costly. States that trade together, the argument goes, are unlikely to fight each other because the economic disruption would be catastrophic for both sides.
The Iran conflict offers a devastating counterexample. The United States has imposed the most comprehensive sanctions regime in history on Iran, targeting its oil exports, its banking system, its access to global finance. This "maximum pressure" campaign was intended to compel behavioral change—to force Iran to negotiate a more comprehensive agreement addressing all aspects of its regional behavior.
Instead, the sanctions have done three things. They have radicalized Iranian politics, empowering hardliners who argue that accommodation with the United States is impossible. They have driven the Iranian economy into deep crisis, creating humanitarian suffering that Mearsheimer quantifies in the millions of deaths. And they have pushed Iran toward closer relations with China and Russia, precisely the outcome the sanctions were meant to prevent .
As scholars using world-systems theory have demonstrated, "When energy is evaluated as an efficient tool for determining capital accumulation in which Iran's energy policies are not directly contributing to the interests of the center, as a result of conflicting interests of outcomes also result in the emergence of distinct attitudes of states towards Iran" . In plain language: because Iran's energy policies do not serve Western interests, the West has used its control over the global financial system to punish Iran, creating exactly the kind of core-periphery conflict that Marxist theory predicts.
The Limits of Democratic Peace
The democratic peace proposition—the empirical observation that democracies rarely if ever fight one another—offers little guidance for the Iran conflict. Iran is not a democracy, at least not in the Western sense, though it does hold regular elections within a theocratic framework. Israel is a democracy, at least in its internal functioning, though its occupation of Palestinian territories complicates its democratic credentials. The United States is a democracy.
But the democratic peace tells us nothing about how democracies interact with non-democracies, which is where most international conflict actually occurs. And in that interaction, the constraints that operate within democratic politics—public accountability, institutional checks and balances, freedom of the press—may actually create pathologies of their own. Democratic leaders may feel compelled to demonstrate toughness against authoritarian adversaries. Public opinion may swing between interventionism and isolationism in ways that create uncertainty. Media coverage may amplify threats and constrain diplomatic flexibility.
The liberal framework, in short, explains why cooperation is possible under certain conditions. It does not explain why those conditions have failed to materialize in the Iran case—except to suggest that the necessary conditions were never fully present.
IV. The Constructivist Intervention: Identity as Independent Variable
If realism explains the war's inevitability and liberalism explains diplomacy's failure, constructivism explains the war's intensity and the apparent irrationality of its persistence.
Constructivism, the school of thought associated most prominently with Alexander Wendt, Nicholas Onuf, and their successors, argues that international relations are not determined solely by material factors—military capabilities, economic resources, geographic position. They are also constituted by ideas, norms, identities, and shared understandings. As Wendt famously declared in his 1992 article "Anarchy is What States Make of It," the international system is what states make of it. Anarchy does not necessarily produce self-help and security competition; it produces those outcomes only when states construct one another as enemies .
The Iran conflict offers a powerful demonstration of this proposition.
The Wendtian Framework Applied
Nicholas Onuf, reflecting on Wendt's contribution nearly three decades after its publication, argues that Wendt succeeded in establishing constructivism as a mainstream theory in International Relations, alongside realism and liberalism . The key insight is that interests are not given by the structure of the international system alone but are constituted by the identities states hold and the meanings they attach to material facts.
Apply this to Iran. The Islamic Republic does not simply have material interests in security and survival. It has an identity—formed in the crucible of the 1979 revolution, shaped by decades of conflict with the United States, articulated through the discourse of the "Resistance Axis" and opposition to global arrogance. This identity is not rhetoric to be stripped away to reveal "real" interests. It is the framework within which interests are understood.
For Israel, the identity is equally constitutive. A state born from the ashes of the Holocaust, surrounded by neighbors that refused to recognize its existence for decades, armed with a narrative of existential vulnerability that shapes every strategic calculation. When Israeli leaders speak of an existential threat from Iran, they are not engaging in hyperbole or domestic political theater. They are expressing a genuine reading of their position in the world, filtered through the identity that constitutes their state.
The Construction of Difference
May Darwich, in her article "Alexander Wendt Meets the Middle East: The Construction of Difference within Collective Identities," explores precisely how identity dynamics operate in the region. She examines "how cooperative relations transform into conflict through processes of interaction" and analyzes "the puzzle of how Saudi Arabia changed and evolved over the years from supporting Hamas and the Palestinian resistance to identifying it as an enemy, despite sharing pan-Islamism as a collective identity" .
The same dynamic operates in Iranian-Israeli relations. These are not just two states with conflicting interests. They are two states whose identities have been constructed in opposition to one another. Iran's identity as the leader of the Islamic world's resistance to Western hegemony requires opposition to Israel, constructed as the ultimate outpost of Western imperialism in the region. Israel's identity as the homeland of the Jewish people, established in the aftermath of genocide and surrounded by hostile neighbors, requires taking seriously every threat emanating from Tehran.
As scholars have noted, constructivism illuminates how "shared ideas, norms, and beliefs that states hold about each other determine their relationship, whether they opt for balancing, cooperation, or war" . The absence of shared identity between Iran and Israel—indeed, the active construction of each as the other's existential enemy—creates a relationship in which even defensive measures are interpreted as offensive threats.
Identity and the Nuclear Question
The identity dimension also illuminates the nuclear question in ways that materialist frameworks cannot. Why should France be allowed nuclear weapons but not Iran? Why does the international community accept Israel's undeclared nuclear arsenal while threatening Iran with military action over its program?
The answer lies not in material capabilities but in the identities of the states involved. France is a Western democracy, a NATO ally, a trusted member of the international community. Israel is a Western-aligned state, a close American partner, a country whose nuclear weapons are seen as a final guarantor of survival rather than a threat to regional stability.
Iran, by contrast, is constructed as a revolutionary state, a supporter of terrorism, a threat to the existing order. Its nuclear program is therefore read through this identity: not as a defensive deterrent but as an offensive capability in the hands of an irresponsible actor. "In international relations there exists a kind of nuclear hypocrisy, so it seems that some countries are permitted to hold nuclear weapons unhindered (five permanent members of the UN Security Council), while others are explicitly forbidden, sometimes at the cost of becoming targets of military intervention" .
This is constructivism's most powerful insight: the same material fact—a nuclear weapon, or the capacity to build one—means different things depending on who possesses it and how that actor is constructed in international discourse.
V. The Marxist Critique: Capital, Core, and Periphery
Finally, there is a perspective largely marginalized in American policy discourse but essential to understanding how the conflict is perceived beyond the West.
Marxist and world-systems theories, associated most prominently with Immanuel Wallerstein and his intellectual heirs, interpret international relations through the lens of global capitalism, core-periphery hierarchy, and the imperatives of capital accumulation. From this perspective, the Iran conflict is not primarily about security or identity. It is about system maintenance.
Core-Periphery Dynamics
World-systems theory divides the globe into a core of advanced capitalist states that dominate the international economy, a periphery of states that provide raw materials and cheap labor, and a semi-periphery that occupies an intermediate position. The core states use their control over finance, technology, and military power to maintain a global division of labor that benefits them disproportionately.
Iran's crime, from this perspective, is not its nuclear program or its support for militant groups. Iran's crime is its refusal to remain subordinate. By challenging American hegemony, by seeking independent alliances with China and Russia, by asserting regional influence without American approval, Iran threatens the hierarchy on which core dominance depends .
Scholars examining Iran's energy politics through a world-systems framework have found that "Iran's energy sector could be adversely affected by those core states'—particularly the USA's—sanctions and embargoes. However, the conflicts of interest among actors, who are aiming to control the international capital accumulation, trigger the further development of Iran's energy sector" . In other words, core states use their power to punish peripheral states that defy them, but contradictions within the core create opportunities for peripheral resistance.
The View from the Global South
This framework explains why the Global South response to the Iran conflict differs so markedly from Western responses. When countries in Latin America, Africa, and Asia refuse to condemn Iran or criticize American strikes, they are not expressing sympathy for the Islamic Republic's ideology. They are expressing a structural skepticism about a system they experience as domination.
They have seen intervention before—in Iraq, in Libya, in Syria, in countless other sites of Western military action justified by universal values but serving particular interests. They have seen sanctions before—comprehensive economic warfare that strangles ordinary citizens while leaving ruling elites relatively untouched. They have seen their own sovereignty violated by powers that claimed to be acting in the name of humanity while pursuing their own strategic objectives.
Mearsheimer's characterization of American policy as "deeply cruel" resonates in the Global South not because his audiences are anti-American but because his analysis confirms what they have experienced. The 38 million deaths he attributes to American sanctions are not abstract statistics. They are the accumulated human cost of a system that prioritizes dominance over human welfare.
Capital Accumulation and Conflict
The Marxist framework also illuminates the material stakes underlying the conflict. Iran sits on the world's fourth-largest proven oil reserves and the second-largest natural gas reserves. Control over these resources, and over the routes by which they reach global markets, is not incidental to the conflict. It is central to it.
"Within the scope of the growing importance of energy in determining the international capital accumulation, the potential of Iran's energy politics and its impact on the international capital accumulation" means that whoever influences Iranian energy policy influences the global economy. A Iran aligned with Western interests and integrated into Western-dominated energy markets is one thing. A Iran aligned with China and Russia, developing independent energy routes, challenging Western control over global energy flows, is quite another.
The conflict, from this perspective, is about whether Iran's resources will be integrated into the Western-dominated global economy on Western terms or whether Iran will succeed in carving out an autonomous space within an increasingly multipolar world.
VI. Neoclassical Realism and Exigency Pragmatism: Toward Synthesis
If the preceding frameworks each capture part of the truth, the question becomes whether they can be synthesized into a more complete explanation. Two theoretical innovations offer promising pathways.
Neoclassical Realism
Neoclassical realism, associated with scholars like Fareed Zakaria and Randall Schweller, attempts to bridge the gap between systemic and unit-level analysis. It accepts the neorealist premise that the distribution of power in the international system sets the parameters for state behavior. But it insists that those systemic pressures are filtered through domestic-level "intervening variables"—leader perceptions, state-society relations, ideology, and domestic political institutions.
Applied to Iran, this framework yields a more nuanced understanding. The systemic pressure of American containment and Israeli opposition is real and powerful. But Iran's response to that pressure is not a simple, rational calculation of power and interest. It is filtered through the prism of revolutionary ideology, through factional domestic politics that pit hardliners against reformers, through historical memory of foreign intervention stretching back to the 1953 CIA-backed coup, through the institutional interests of the Islamic Revolutionary Guards Corps, through the economic constraints of a command economy subjected to decades of sanctions .
The result is a foreign policy that is strategic but not purely strategic, rational but not purely rational, responsive to systemic pressures but also shaped by domestic dynamics that purely structural theories cannot capture.
Exigency Pragmatism
Scholars at Tarbiat Modares University in Tehran have developed a complementary framework specifically tailored to understanding Iranian behavior. They propose the concept of "exigency pragmatism" as a lens for analyzing Iran's conduct in regional conflicts .
According to this framework, "Iran adopts a security-centric and pragmatic approach in regional conflicts, characterized by defensive, tactical, and situational responses that prioritize regime survival and national security." This approach "seeks to reconcile identity-driven (ideological) motives with geopolitical imperatives, positioning Iran's behavior at the intersection of structural constraints and agency-based choices" .
The concept is elaborated as a dual construct:
· "Exigency" captures the sense of acute threat and external constraints that shape decision-making
· "Pragmatism" reflects Iran's emphasis on instrumental rationality and policy flexibility
Key indicators of this behavioral pattern include: situational and single-dimensional pragmatism, convergence of threat urgency with action urgency, operational environment taking precedence over formal diplomacy, cooperative tendencies in conflicts along connected borders, competitive behavior in conflicts along disconnected borders, and an offensive defense posture .
The framework's findings across multiple case studies—Afghanistan, Iraq, Syria, Lebanon, Yemen, Palestine, and the South Caucasus—reveal that "Iran's foreign policy is not driven by a rigidly aggressive or purely ideological logic. Instead, it is shaped by cost-benefit assessments, tactical flexibility, and a security-driven pragmatism responsive to contextual demands" .
This analysis suggests a more complex picture than either the "mad mullahs" narrative prevalent in Western discourse or the "resistance axis" narrative prevalent in Iranian discourse. Iran is a security-seeking state operating in an extraordinarily hostile environment, with an ideology that shapes its perception of threats and opportunities but does not determine its responses in any simple or predictable way.
VII. The Empirical Record: Testing Theory Against Events
The theoretical frameworks surveyed above are not merely academic abstractions. They can be tested against the empirical record of the conflict.
The Nuclear Trajectory
Iran's nuclear program has followed a trajectory that various theories explain in different ways. Realists point to the security imperative: Iran seeks nuclear capability because it faces existential threats from nuclear-armed adversaries. Constructivists point to identity: Iran's nuclear program is also about status, about recognition, about asserting the country's place in the international hierarchy. Liberals point to institutional failure: the collapse of the JCPOA removed constraints and validated hardliners. Marxists point to core-periphery dynamics: Iran's pursuit of nuclear capability is a form of resistance to core dominance.
The empirical record offers support for multiple interpretations. According to the IAEA's May 2025 report, Iran's stockpile of 60% enriched uranium had reached 408.6 kilograms—enough, as every physicist knows, to be converted in less than three weeks into material sufficient for several nuclear bombs . Iran has also expelled IAEA inspectors, removing the last vestiges of international oversight.
Yet Iran has not tested a nuclear weapon. It has not withdrawn from the Non-Proliferation Treaty. It has not declared itself a nuclear weapons state. This suggests a strategy of what analysts call "nuclear latency"—remaining just below the threshold of weaponization, close enough for deterrence but not so close as to trigger an irrevocable regional reaction or provoke the military response that crossing the threshold might invite.
Senior Revolutionary Guards general Yahya Rahim Safavi's recent statement captures this ambiguity: "We are not in a ceasefire, we are in a stage of war. No protocol, regulation, or agreement has been written between us and the US or Israel. I think another war may happen, and after that, there may be no more wars" . The allusion to nuclear retaliation is unmistakable.
The Israeli Calculus
Israel's behavior also tests competing theoretical frameworks. A study examining Israeli conduct against Iran between 2007 and 2020 tested defensive and offensive realism against the empirical record and concluded that "defensive realism possesses greater explanatory power when applied upon the Israeli conduct against Iran, compared with offensive realism" .
This finding suggests that Israel's actions, however aggressive they may appear, are best understood as responses to perceived threats rather than as expressions of expansionist ambition. Israel strikes Iranian facilities and assassinates Iranian scientists not because it seeks to dominate the region but because it fears that a nuclear-armed Iran would pose an existential threat to its survival.
Whether this perception is accurate is a separate question. The point is that Israeli behavior is consistent with a defensive realist framework: states that feel existentially threatened take extraordinary measures to eliminate the threat before it matures.
The American Role
The United States presents a more complex case. Mearsheimer's offensive realism would predict that the United States, as the dominant power in the international system, would seek to prevent the emergence of any regional hegemon that might challenge its position. This prediction is consistent with American behavior across multiple administrations.
Yet the American record is also marked by inconsistency. The Obama administration negotiated the JCPOA, accepting a limited agreement that left Iran's regional behavior unaddressed. The Trump administration withdrew from that agreement and escalated pressure. The Biden administration attempted to negotiate a return to compliance but was overtaken by events. This inconsistency suggests that domestic politics, leader perceptions, and partisan competition—the variables that neoclassical realism emphasizes—play a significant role in shaping American policy.
VIII. Conclusion: The Theoretical Bottom Line
The conflict with Iran is not an anomaly in international relations. It is not a deviation from normal state behavior or a product of particularly malign leaders or uniquely pathological ideologies. It is international relations in its purest form—the bedrock of anarchy revealed when the topsoil of order is stripped away.
What we are witnessing is a tragedy in the classical sense: not a conflict between good and evil but a conflict between security-seeking actors whose efforts to protect themselves inevitably threaten others. The security dilemma operates whether we acknowledge it or not. The balance of power adjusts whether we manage it or not. Structure constrains whether we believe in it or not.
The liberal institutions designed to manage such conflicts have proven too fragile to contain them. The JCPOA lies in ruins. The IAEA's oversight has been eviscerated. The UN Security Council is paralyzed by great power division. The habits of cooperation that liberals hoped would gradually transform international politics have been replaced by habits of suspicion and conflict.
The identities that constructivism emphasizes have become cages from which neither side can escape. Iran cannot abandon its revolutionary identity without undermining the regime's legitimacy. Israel cannot treat Iranian threats as anything less than existential without violating its foundational narrative. These identities are not rhetoric; they are the frameworks within which interests are understood and options are evaluated.
The global hierarchy that Marxist theory identifies is increasingly visible to those on its receiving end. The Global South watches as core states deploy military force against peripheral states that defy them, and draws predictable conclusions about the nature of the international system.
And the neoclassical realist synthesis reminds us that these structural pressures are always filtered through particular histories, particular ideologies, particular domestic configurations. Iran's response to American pressure is not a simple function of power calculations. It is refracted through the memory of 1953, through the discourse of revolutionary legitimacy, through the institutional interests of the Revolutionary Guards, through the factional competition between hardliners and reformers.
The missiles falling on the Middle East carry the weight of all these theories. They carry the security dilemma that Herz identified, the structural constraints that Waltz analyzed, the offensive imperatives that Mearsheimer described, the institutional failures that liberals lament, the identity constructions that Wendt theorized, the core-periphery hierarchies that Wallerstein mapped, and the domestic filters that neoclassical realists emphasize.
In the stark language of international relations theory, we are watching what happens when the thin veneer of the liberal world order peels back, revealing the enduring, unforgiving bedrock of anarchy beneath. The mask is off now. And what's underneath is what theorists have been describing for centuries: an anarchic world where security is scarce, where fear is rational, and where war is always waiting just below the surface.
As Iran's General Safavi put it, with the grim clarity of those who have seen too much: "I think another war may happen, and after that, there may be no more wars" . In that single sentence, he captured the entire logic of nuclear deterrence—and the entire tragedy of the conflict that preceded it.
