Christopher Nolan's latest film The Odyssey transcends its ancient Greek setting to deliver a surprisingly penetrating commentary on the erosion of global order in our time. While viewers expecting a straightforward adaptation of Homer's epic may leave the cinema thinking primarily of Odysseus and his journey home, the deeper resonance of Nolan's vision extends far beyond mythology into the realm of contemporary international relations. The director has embedded within his storytelling a cautionary tale about power, perspective, and the perils of abandoning principle when strategic convenience beckons. This unexpected political dimension elevates the film beyond mere spectacle into the territory of genuine intellectual provocation.

The narrative mechanics of Nolan's adaptation hinge on a central irony that proves crucial to understanding his broader commentary. Throughout the film, Mediterranean civilisations live in terror of the Sea Peoples—mysterious raiders emerging from the ocean, bringing violence and chaos wherever they land. Local populations regard these marauders with existential dread, spreading tales of their ruthlessness as villages prepare defences against an external threat. Yet as the story unfolds, audiences discover an unsettling truth: these feared invaders are largely Greek warriors themselves, returning home from Troy and laying waste to foreign shores in the process. The conquerors of Troy become, from the perspective of those they encounter, destructive marauders descending upon innocent populations. The dramatic power of this revelation lies in its exposure of how historical narratives shift depending on who wields the pen—or the sword.

This narrative device captures a fundamental historical truth that extends well beyond ancient Mediterranean geopolitics. The distinction between liberator and conqueror, between defender and aggressor, often rests not on objective fact but on perspective and positioning. Those who perceive themselves as righteous champions of justice may be remembered by those on the receiving end of their actions as imperial forces imposing their will through superior force. Nolan recognises that heroes and villains occupy fluid categories, that the moral clarity we impose on historical events often obscures more complex realities. This insight holds particular relevance when examining how dominant powers justify their actions and how those same actions are perceived by other actors in the international system.

For nearly eight decades following the conclusion of the Second World War, the United States emerged as the principal architect and custodian of what became known as the liberal international order. American statecraft focused on constructing institutional frameworks and normative structures explicitly designed to prevent the recurrence of great-power conflict. The United Nations, established in San Francisco in 1945, embodied the principle that collective security should supersede unilateral action. The Bretton Woods Agreement created mechanisms for economic cooperation and stability. An open trading system promised mutual prosperity and interdependence as alternatives to mercantilist competition. Collective defence arrangements, from NATO to bilateral security treaties, created networks of mutual obligation. Underlying all these frameworks was a foundational commitment to legal order governing relations between states—the proposition that international law and established rules should constrain power rather than force alone determining outcomes.

America's most profound achievement during this period extended beyond military dominance or economic preponderance. Washington successfully convinced much of the developed world, and sections of the developing world, that embracing an ordered international system served everyone's interests more effectively than reverting to anarchic great-power competition. This represented an extraordinary feat of statecraft and soft power. The very concept that sovereign states might voluntarily constrain themselves through law and institutional membership, that rule-based order constituted enlightened self-interest, took root in post-war consciousness. The liberal order became the default assumption for how advanced industrial democracies should organise their relationships, and the United States gained immense influence by positioning itself as this system's chief defender and beneficiary.

Today, however, that carefully constructed edifice shows unmistakable signs of strain and fracture. Confronted with intensifying strategic competition from rising powers and non-state actors, the United States has increasingly displayed a willingness to circumvent or reinterpret the very principles upon which this order rests. Economic pressure through tariffs and comprehensive sanctions regimes has become a primary foreign policy tool, often applied without the multilateral consultation or legal frameworks that characterised earlier periods. Washington has withdrawn from international agreements—climate accords, arms control treaties, multilateral trade arrangements—with limited explanation or alternative proposals. Unilateral military actions have occurred with diminishing reference to international law or United Nations authorisation. Supply chain weaponisation and restrictions on technology transfer represent new frontiers in great-power competition, deployed selectively based on national interest calculations rather than consistent principle.

The accumulation of these shifts creates a pronounced and troubling irony that deserves careful examination. The liberal international order was specifically constructed to prevent precisely the kind of unconstrained great-power behaviour that the United States increasingly exhibits. That original post-war consensus held that unfettered power—the ability of dominant states to act unilaterally in pursuit of narrow national interest—generated instability, miscalculation, and ultimately conflict. The entire institutional architecture of the liberal order embodied the principle that even the most powerful nations should accept constraints on their freedom of action. Yet the very state that designed and championed this system of constraints now demonstrates growing impatience with those same constraints whenever they prove inconvenient.

This trajectory transforms the United States, paradoxically, into something resembling the very actor its own post-war order was explicitly designed to restrain. The original architects of the liberal system understood themselves as preventing a recurrence of 1930s-style great-power anarchy, where revisionist states pursued their interests through force and intimidation. They built institutional mechanisms and legal frameworks to prevent dominant powers from exercising hegemonic authority without constraint. Yet by increasingly ignoring these mechanisms and frameworks, by demonstrating that rules apply selectively based on power calculations, the United States begins to resemble precisely the unconstrained hegemonic actor that liberal institutionalists feared and sought to prevent.

Nolan's cinematic device of the Sea Peoples illuminates this paradox with particular clarity. The people of Ithaca fear mysterious raiders from across the sea, imagining threats materialising from beyond their horizons. They construct their politics and security arrangements around this external danger, never recognising that the danger they fear emerges partly from sources within their own world. The parallel to contemporary American geopolitics proves uncomfortably apt. Much of Washington's current strategic discourse focuses on external threats—rising China, resurgent Russia, non-state actors—presenting these as dangers requiring departure from established norms and rules. Yet this framing obscures how American actions themselves contribute to the very dynamics it claims to oppose. Rivals respond to American tariffs with retaliatory measures. Nations withdraw from agreements when Washington withdraws first. Trust in the liberal order erodes when its most powerful member demonstrates willingness to abandon it.

The implications for Southeast Asia and the broader Indo-Pacific region deserve particular attention. Many regional states have built their security strategies and economic policies on the assumption of a rules-based international order underwritten by American commitment to liberal principles and institutional frameworks. Malaysia, Singapore, Vietnam, Indonesia, and other regional players positioned themselves to benefit from open trading systems, freedom of navigation, and dispute resolution through international law rather than military coercion. These calculations face fundamental uncertainty if the principal architect of this order no longer reliably defends it. Regional states must now contemplate uncomfortable questions: if the dominant power demonstrates willingness to ignore multilateral rules when convenient, should other powers similarly abandon constraints on their behaviour? If great-power competition increasingly trumps commitment to shared norms, what happens to smaller powers dependent on rules-based order for their security and prosperity?

Moreover, the deterioration of American commitment to liberal order creates opportunities for alternative power arrangements that may prove far less favourable to Southeast Asian interests. Chinese assertions of authority in the South China Sea directly challenge the freedom of navigation and territorial integrity principles that underpin the existing order. If that order lacks effective defenders, regional states may find themselves adapting to new realities shaped by raw power calculations rather than legal principle. The economic dimensions prove equally important: a world of fragmented supply chains, weaponised technology transfers, and tariff-based competition disadvantages smaller trading nations dependent on openness and predictability.

Nolan's film ultimately suggests that the greatest threats to any order rarely emerge from external sources attacking from beyond established boundaries. More commonly, erosion occurs when those entrusted with defending a system gradually transform themselves into something resembling the forces they once opposed. The liberal international order faces not primarily from rival powers explicitly rejecting its premises, but from the widening gap between the principles the system claims to uphold and the practices its most powerful member increasingly employs. This represents a form of internal contradiction more corrosive than external challenge. As American actions increasingly diverge from liberal internationalist rhetoric, other powers gain justification for their own departures from shared norms, and the entire framework unravels not through dramatic collapse but through gradual erosion of mutual commitment.

The question facing policymakers and analysts concerns whether this trajectory remains inevitable or whether recognition of the Odyssey's central irony might prompt course correction. Understanding how power and perspective interact—how those conceiving themselves as liberators may appear to others as marauders—offers potential insight for charting a different path. A genuine recommitment to the liberal order would require the United States to demonstrate consistent adherence to the principles it championed, applying rules evenhandedly rather than selectively, and working through multilateral institutions rather than circumventing them. Whether such a course proves politically feasible in contemporary American politics remains an open question, but the costs of continued departure from liberal order principles grow increasingly apparent.
