Christopher Nolan's The Odyssey delivers the director's trademark visual spectacle and narrative complexity, but beyond the ancient Greek mythology lies an unsettling contemporary resonance. The film traces Odysseus's decade-long struggle to return home after the Trojan War, complete with divine obstacles and mythical adversaries. Yet woven throughout this epic is a more modern commentary on power, perception, and the fragility of international systems—one that speaks directly to the contemporary crisis afflicting the rules-based global order.

The film's most compelling motif centres on the Sea Peoples, a mysterious and feared maritime menace that haunts the Mediterranean. These shadowy raiders are spoken of with dread throughout the narrative, depicted as an external threat to civilization itself, an ominous force that kingdoms must defend against. Citizens whisper nervously about who might emerge from beyond the horizon next, and the mere rumour of their approach sends tremors through established communities. Yet Nolan orchestrates a narrative revelation that reframes this entire dynamic: the Sea Peoples that inspire such terror are, in substantial measure, Greek themselves. The very warriors and fleets that destroyed Troy, returning homeward across contested waters, have become the marauders that neighbouring civilizations fear. What appeared to external observers as liberation or righteous conquest registers to those bearing the brunt of Greek military power as brutal conquest and upheaval.

This cinematic irony captures something profound about human history and international relations. The distinction between liberator and conqueror, between defender and aggressor, often dissolves upon examination. It depends entirely on perspective—on which shore you inhabit, which civilization bears the costs of military campaigns marketed as necessary and righteous. Heroes in one's own national mythology become villains in the stories told elsewhere. Nolan's insight here extends beyond clever storytelling into genuine historical wisdom: those who believe themselves to be upholding civilization may appear to others as its greatest threat.

This lesson carries uncomfortable implications for understanding contemporary American power and the deteriorating state of the liberal international order. For more than seventy years following the Second World War, the United States positioned itself as the principal custodian and architect of a rules-based global system. Washington championed multilateral institutions, legal frameworks, and norms explicitly designed to prevent the emergence of unconstrained great-power competition. The United Nations, the Bretton Woods system, open trading arrangements, and collective security agreements all reflected a singular ambition: to replace the anarchic world of power politics with a world where international law constrained state behaviour and predictability supplanted the constant threat of force.

America's unparalleled achievement during this era was not merely military or economic dominance, though both were considerable. Rather, it was the capacity to convince much of the world—allies, neutral nations, and even some adversaries—that this liberal international order served broader interests beyond American hegemony. The system promised that smaller states could pursue development and security without constant fear of predation from stronger neighbours. It suggested that disputes could be adjudicated through law rather than settled through warfare. For several decades, this vision possessed genuine persuasive power across diverse populations and political systems.

Today, however, that architecture appears increasingly hollow and compromised. As the United States encounters intensifying strategic competition from rising powers and faces constraints on its dominance, it has progressively abandoned the very principles it once championed. Economic coercion through tariffs and sanctions, selective application of international law depending on strategic convenience, withdrawal from multilateral agreements, unilateral military interventions that bypass collective decision-making, and the weaponisation of global supply chains—these practices contradict the fundamental logic of the liberal order. They signal that rules apply selectively, binding weaker states while remaining optional for the powerful.

The irony is difficult to overstate. The liberal international order was constructed explicitly to prevent powerful states from behaving as classical great powers did—pursuing interests through force, dominating weaker neighbours, and treating international agreements as temporary conveniences rather than binding constraints. Yet the system's chief architect increasingly demonstrates precisely this behaviour, treating the rules it created as negotiable when they conflict with immediate national interests. The United States risks becoming the unconstrained hegemon its own post-war order was designed to restrain and prevent.

For Southeast Asian states and other regional powers, this transformation carries profound implications. Nations across the region have built development strategies and security approaches on the assumption that a rules-based international system would constrain hegemonic behaviour and protect smaller states from coercion. They invested in multilateral institutions, open trade, and legal frameworks partly because these mechanisms promised to level an unequal playing field. As the United States demonstrates increasing willingness to suspend these very rules, regional states face a destabilising recalibration. The security guarantees that undergirded regional stability become less reliable. The trading system that enabled prosperity becomes less predictable. The institutions that offered a forum for smaller states to influence outcomes become less relevant.

Nolan's Sea Peoples allegory becomes particularly resonant here. The people of Ithaca fear tales of savage marauders approaching from across the sea, never recognising that the threat they dread originates from their own countrymen returning home with the habits and attitudes of conquerors. Similarly, international observers have long focused on external threats to American-led order—rising powers, revisionist states, non-state actors—while overlooking a more fundamental danger: the possibility that the system's chief architect would gradually abandon its founding principles and begin to resemble the very type of unconstrained great power the order was designed to prevent.

This transformation occurs not through dramatic rupture but through incremental normalisation. Each deviation from established rules—each unilateral action justified as exception, each reinterpretation of international law to permit preferred outcomes, each selective application of principles—becomes the new baseline. Over time, the cumulative effect transforms the character of international relations. What once seemed exceptional becomes routine. What once appeared as violation of principle becomes standard practice. The guardian gradually becomes indistinguishable from the predator.

The deepest warning embedded within Nolan's adaptation concerns not external threats but internal decay. Civilisational systems rarely collapse due to invasion by clear external enemies. Rather, they deteriorate when those entrusted with maintaining them abandon their foundational commitments. The Sea Peoples are most dangerous precisely because they carry the weapons, legitimacy, and knowledge of Greek civilisation itself. Similarly, the liberal international order faces its greatest existential threat not from rivals external to the system but from its principal beneficiary and architect progressively disassembling it from within.

For regional players navigating these currents, the imperative becomes increasingly clear. As the United States recalibrates its relationship to the rules it created, other powers must accelerate their efforts to strengthen alternative mechanisms for regional cooperation and dispute resolution. The assumption that American power would maintain order and respect legal constraints has become untenable. Building resilience requires diversifying partnerships, strengthening multilateral institutions independent of American participation, and developing alternative frameworks for managing regional security and economic relations. The unravelling of the liberal international order, once unthinkable, now demands practical preparation.
