Christopher Nolan's latest film adaptation of Homer's Odyssey emerged as far more than a spectacle of ancient Greek heroics and visual grandeur. While viewers might expect to leave the cinema contemplating the hero's decade-long struggle to return home from the Trojan War, the narrative carries unsettling implications for understanding contemporary global politics and the trajectory of American power in the 21st century.

The film faithfully traces Odysseus's perilous journey across the Mediterranean, where he confronts mythological creatures and divine obstacles. Meanwhile, back in Ithaca, his wife Penelope resists pressure to remarry, and their son Telemachus seeks knowledge of his father's whereabouts. The familiar tale culminates in Odysseus's return, his reclamation of his household, and the destruction of the suitors who had threatened his domain. Yet beneath this epic framework lies a narrative thread that extends beyond ancient history into modern international relations: the haunting fear of the Sea Peoples.

Throughout Nolan's interpretation, the Mediterranean world trembles at rumours of mysterious raiders descending from the ocean, leaving devastation in their wake and instilling dread among coastal kingdoms. These figures exist as faceless threats, external menaces to civilisation itself, spoken of with the kind of existential anxiety that transcends ordinary military conflict. Inhabitants speak of potential invasion with the urgency of civilisations facing their own extinction. Yet the film's central irony reveals itself gradually: the very Greeks celebrated as heroes and liberators were themselves the source of this terror. Having destroyed Troy through warfare and conquest, Greek fleets homeward-bound descended upon foreign shores with violence and disruption, creating the very conditions that spawned the fearful legends of the Sea Peoples. The rumours that reach Ithaca's shores, which supposedly necessitate choosing a new king during Odysseus's absence, derive from Greek actions themselves.

This narrative construction transcends clever storytelling and touches upon a fundamental historical paradox that Nolan appears deliberately to be highlighting. Throughout human history, those who perceive themselves as liberators and champions of justice have often appeared to others as conquerors and destroyers. The distinction between heroes and marauders frequently depends entirely upon perspective, geography, and whose story gets told. A military expedition celebrated as liberation in one capital may be remembered as invasion in another. This tension between self-perception and external reality has shaped international relations since ancient times.

The parallel to contemporary American foreign policy requires careful examination. For nearly eight decades following the Second World War, the United States positioned itself as the principal architect and guarantor of a liberal international order explicitly designed to prevent the repetition of great-power aggression that had characterised the 20th century's catastrophic conflicts. American policymakers championed multilateral institutions, internationally agreed-upon rules, economic systems designed to promote interdependence, and the principle that state behaviour should be constrained by law rather than raw power. The United Nations, the Bretton Woods framework, the General Agreement on Tariffs and Trade, NATO, and the principle of sovereign equality all embodied this vision.

America's most significant contribution to global stability extended beyond military superiority or economic dominance. Rather, it lay in persuading much of the international community that orderly rules governing state behaviour represented a preferable alternative to anarchic great-power competition. This represented a genuine ideological achievement, even if its implementation remained uneven and often inconsistent. Nations accepted constraints on their conduct because they believed the system itself protected their interests and prevented the recurring cycles of hegemonic war that had devastated the previous century.

Yet in recent years, this foundational bargain has visibly deteriorated. Confronting intensifying strategic competition from rival powers and facing domestic political pressures, American policymakers have increasingly demonstrated willingness to circumvent or reinterpret the very principles upon which the liberal order rested. Economic coercion through unilateral tariffs, extraterritorial sanctions regimes, withdrawal from multilateral agreements designed to manage shared challenges, unilateral military interventions undertaken without international authorisation, and the weaponisation of global supply chains have all contributed to a widespread perception that American commitment to rules-based order now extends only to those circumstances where such rules serve immediate national interests.

The irony becomes difficult to overlook for observers of international relations. The liberal international order was constructed explicitly to prevent powerful states from acting as unconstrained great powers pursuing interest without regard to law or others' legitimate concerns. Yet the order's principal architect increasingly exhibits precisely this behaviour. When the United States bypasses institutions it created, reinterprets agreements it championed, and employs coercive economic tools to advance geopolitical objectives, it adopts the posture of a great power acting without restraint—precisely the behaviour the post-war order was designed to prevent. In this transformation, the United States risks becoming the very actor its own institutional framework was engineered to restrain.

Nolan's depiction of the Sea Peoples resonates with particular force in this context. The inhabitants of Ithaca and surrounding lands fear the mysterious raiders not because of direct experience with them but because of rumours and stories of destruction. They imagine danger arriving from beyond the horizon, never recognising that those inspiring such terror might be their own countrymen returning home from conquest. The psychological dynamic here merits careful attention: citizens fear the unknown external threat while remaining blind to actions taken by their own society that generate that fear elsewhere. Fear and threat perception become distorted by this lack of recognition.

This same paradox increasingly surrounds discussions of American leadership in international forums. Policymakers in Washington express deep anxiety regarding challenges to American-led order from rising powers and non-state actors, viewing such challenges as threats to stability itself. Yet these very challenges have been substantially provoked by American actions that others perceive as rule-breaking, coercive, and destabilising. Just as the Greek warriors could not recognise themselves in the frightening legends of the Sea Peoples, contemporary American leaders struggle to perceive how their own conduct appears to others as precisely the kind of unconstrained power-seeking that prompted the creation of the liberal order in the first place.

The film's deeper warning suggests that the greatest threats to any established order rarely originate from outside. Rather, they emerge when those entrusted with defending and maintaining the system gradually come to resemble the very forces they once opposed. As the United States increasingly behaves as an unconstrained great power, it fulfils the predictions of those who never trusted American benevolence and validates the strategic calculus of rising powers that the rules-based order cannot be relied upon to protect their interests. The tragedy lies not in external conquest but in self-inflicted erosion.

For Southeast Asian nations navigating great-power competition, these dynamics carry particular significance. Regional states have long benefited from an international order that privileged smaller nations' rights to non-interference and provided mechanisms for dispute resolution without recourse to force. As that order weakens, these nations face diminished protection precisely when regional tensions intensify. Whether Washington recognises the historical parallel to the Sea Peoples remains uncertain, but the consequences of its current trajectory will reshape global politics for decades to come.
