Christopher Nolan's latest film adaptation of Homer's classic epic delivers more than polished cinematography and intricate storytelling. For viewers attuned to contemporary geopolitics, The Odyssey offers an unexpectedly penetrating commentary on the fragmentation of the international system that has governed global affairs since 1945. The film's narrative architecture—particularly its treatment of the mysterious Sea Peoples as both feared external threat and inadvertent creation of the Greek civilization itself—provides a startling mirror to the trajectory of American power and the gradual unravelling of the rules-based order Washington constructed and championed for nearly eight decades.

The mythological framework Nolan employs centres on Odysseus's gruelling decade-long voyage home from Troy, during which he confronts gods, monsters, and the hostile seas themselves. Simultaneously, his wife Penelope resists suitors attempting to claim his throne while their son Telemachus seeks information about his father's fate. Yet beneath this familiar epic adventure lies a darker, more unsettling layer. Throughout the Mediterranean world depicted in the film, panic spreads about the Sea Peoples—shadowy marauders who emerge from the ocean to pillage coastal settlements, destroy kingdoms, and instil terror in populations helpless against their raids. These mysterious invaders become the defining threat of the age, with kingdoms mobilizing defences and populations gripped by existential anxiety about who might materialize over the horizon next.

The film's crucial irony—and the element that lingers most powerfully after the credits roll—involves the revelation that these feared Sea Peoples are not some alien civilization of external origins. Rather, they represent the Greek forces themselves, particularly the victorious armies returning home from Troy. The same fleets that had conquered an enemy city-state now traverse the Mediterranean, landing on foreign shores and unleashing violence and chaos in their wake. The Greeks, having defined themselves as liberators and champions of justice against Trojan aggression, find themselves remembered by neighbouring peoples as raiders and conquerors. Rumours of these Greek marauders even reach Ithaca, where they serve as justification for installing a new king to replace the absent Odysseus. This inversion—where heroes become villains depending on perspective—transcends clever filmmaking; it articulates a fundamental historical truth that resonates across centuries and continents.

The distinction between liberator and conqueror, between champion of order and wielder of overwhelming force, depends entirely on one's position within the power hierarchy. Those who view themselves as defending civilization and law often appear to others as instruments of subjugation and arbitrary domination. What one society frames as legitimate security measures or necessary interventions another experiences as coercive aggression. This perspective-dependent reality carries profound implications for understanding contemporary international relations and specifically for analysing the American role in the post-war system. For much of the second half of the twentieth century and into the early twenty-first, the United States positioned itself as the principal guarantor and defender of a liberal international order based on law, consensus-building, and multilateral institutions.

Washington championed the creation and maintenance of structures explicitly designed to prevent a return to the great-power competition that had culminated in two devastating world wars. The United Nations provided a forum for dispute resolution; the Bretton Woods framework and subsequent trade arrangements promised prosperity through economic integration; collective security alliances pledged mutual defence against aggression; and the fundamental principle of respecting state sovereignty offered protection against powerful actors simply imposing their will through brute force. These institutions and norms were not presented as serving narrow American interests alone but as universal goods benefiting all states large and small. The American argument held that predictability, transparency, and rule-based governance served everyone's interests better than a return to anarchic great-power competition.

This represented perhaps America's most significant diplomatic achievement during the post-war era—not the accumulation of military bases, nuclear weapons, or trade surpluses, but rather the persuasion of much of the world that an ordered, rules-governed international system provided superior outcomes to the historical alternative of unrestrained power competition. Even nations that resented American predominance acknowledged the utility of institutions that constrained all actors, including hegemonic ones. The liberal international order functioned, however imperfectly, because the dominant power had committed to binding itself through rules and multilateral processes. This self-imposed restraint lent the system legitimacy and made the sacrifices smaller nations accepted seem worthwhile.

Yet increasingly, that foundational bargain appears to be fracturing. Confronted with intensifying strategic competition, particularly from rising powers challenging American predominance, Washington has demonstrated growing willingness to bypass, reinterpret, or simply ignore the very principles and institutions it once championed. Economic coercion through tariffs and sanctions has escalated dramatically, often deployed with minimal regard for the multilateral consensus-building that once characterized American trade policy. Selective enforcement of international law—prosecuting violations by adversaries while ignoring similar actions by allies—has undermined claims of principled consistency. Withdrawals from multilateral agreements covering everything from climate change to nuclear weapons have signalled that American interests now supersede collective commitments. Unilateral military actions, conducted without Security Council authorization or sustained coalition support, contradict the collective security framework the United States helped establish. The weaponization of global supply chains and financial systems, using access to American markets or dollar-denominated transactions as tools of coercion, represents a fundamental departure from the open, rules-based economic order that underpinned postwar prosperity.

The paradox that emerges from this behaviour borders on the tragic in its dimensions. The liberal international order was explicitly constructed to prevent precisely the kind of unconstrained great-power behaviour now increasingly evident in American foreign policy. The architects of 1945 had studied the interwar period and the catastrophic failures of the League of Nations; they resolved that the post-war system would bind even the most powerful states through rules, transparency, and multilateral decision-making. Yet the principal architect and guarantor of that order now appears increasingly willing to suspend those constraints whenever doing so serves perceived national interests. The irony recalls Nolan's depiction of the Sea Peoples perfectly—those feared as external threats to civilization turn out to be civilization's own representatives.

The populations of ancient Mediterranean kingdoms lived in dread of mysterious raiders emerging from the sea, constructing narratives around shadowy invaders whose very foreignness explained their savagery. They never considered that the source of their anxiety might originate from within their own world, from the very civilization claiming to represent order and justice. Similarly, contemporary international discourse often frames challenges to the liberal order as coming primarily from external sources—rising authoritarian powers, revisionist states seeking to overturn the postwar settlement, rogue actors operating beyond the system's bounds. Yet increasingly, the greatest threat to the order appears to originate from those entrusted with maintaining it.

This transformation carries particular significance for Southeast Asian nations and other smaller powers that have historically benefited from the liberal international order. Malaysia, like other middle powers in the region, gained substantial advantages from an open trading system, predictable rules governing maritime navigation and resource access, and institutional channels for pursuing disputes without resorting to military force. The system provided smaller nations with leverage and protection they could never have secured through bilateral power competition. A world of unconstrained great powers pursuing zero-sum competition offers far bleaker prospects for medium-sized economies than a rules-based order nominally available to all states.

The deeper warning embedded in Nolan's narrative concerns the self-undermining nature of hegemonic power. Orders built by and for dominant states contain inherent vulnerabilities; they ultimately depend on restraint by those with power to overturn them. Once hegemonic restraint erodes—once the dominant power begins treating the order's rules as optional rather than obligatory—the system's legitimacy evaporates rapidly. Smaller states recognize that they have ceased to be members of a genuine multilateral order and instead inhabit a world of hierarchy and contingent favour. This realization typically accelerates defection from the order, as states seek alternative arrangements or pursue autarkic strategies. The irony reaches its culmination when the order's architect finds itself increasingly isolated and its influence diminished—not because any rival has successfully challenged it militarily or economically, but because it has rendered the order itself obsolete through its own behaviour.

The question now facing policymakers, particularly those in nations dependent on a functioning international system, concerns what might replace the fraying liberal order. Will great powers negotiate a new framework, or will the world drift toward a more fragmented system of regional hegemonies and competing spheres of influence? For Malaysia and Southeast Asia broadly, the stakes of this transition could scarcely be higher. These regions' prosperity and security have been predicated on rules, openness, and the ability to navigate between competing powers without choosing permanent sides. A world of unconstrained great-power competition offers far grimmer prospects than the imperfect but functional system of the recent past.
