Christopher Nolan's latest film The Odyssey delivers the technical brilliance and narrative sophistication audiences expect from the acclaimed director. Yet beneath its epic storytelling lies a surprisingly sharp commentary on contemporary international relations, one that resonates deeply with the fracturing of the global order that shapes Southeast Asia's strategic environment today.

The film adapts Homer's classical epic with modern sensibilities, following Odysseus on his decade-long journey home from Troy while his wife Penelope and son Telemachus navigate treacherous political circumstances in Ithaca. Yet the most striking narrative element—one that lingers long after the credits—centers on the Sea Peoples, mysterious raiders whose rumoured depredations terrify Mediterranean kingdoms. Citizens whisper fearfully of these savage invaders descending from distant waters, unleashing destruction and chaos. The film's central irony reveals these dreaded marauders as Greek sailors themselves, returning home from Troy and inadvertently becoming the very threat their own society feared. This narrative twist encapsulates a timeless historical truth: those who perceive themselves as righteous liberators may appear to others as brutal conquerors, with perspective alone separating heroes from villains.

This sophisticated storytelling device offers a penetrating lens through which to examine American power's trajectory and the deteriorating liberal international order that has structured global relations since World War II. For nearly eighty years, the United States served as the principal architect and guarantor of a rules-based international system explicitly designed to prevent the recurrence of great-power conflict. Washington invested tremendous diplomatic and material resources in establishing institutions—the United Nations, the International Monetary Fund, the General Agreement on Tariffs and Trade—and embedding principles of sovereign equality, collective security, and legal constraint on state behaviour. The system was not perfect in its application, yet its fundamental purpose remained consistent: to subordinate raw military and economic power to negotiated rules and institutional frameworks.

America's most enduring achievement was not military superiority or economic output, though both proved decisive. Rather, it was the ideological and diplomatic success in persuading much of the world, including former enemies, that international order governed by law represented a preferable alternative to anarchic great-power competition. Through patient institution-building and credible commitment to its own rules, Washington cultivated legitimacy for a system that constrained even American itself in meaningful ways. This created a virtuous cycle wherein weaker states accepted American leadership partly because doing so meant gaining access to predictable, rule-bound frameworks that limited arbitrary exercises of power.

Today, however, this carefully constructed architecture exhibits deepening cracks. Confronted with rising strategic competition from China and Russia, the United States has progressively abandoned the self-restraint that once distinguished its leadership. Economic coercion through unilateral tariffs and sanctions, selective invocation of international law, withdrawal from multilateral agreements deemed restrictive, military interventions without Security Council authorization, and aggressive manipulation of global supply chains have collectively transmitted a message to other states: the rules apply flexibly, contingent on American national interest. This represents a profound inversion of the post-war bargain, wherein restraint and rule-following were supposed to separate America's order from the lawless power politics of earlier eras.

The strategic implications for Southeast Asia prove particularly significant. Regional states constructed their own foreign policies on the assumption that American power, however dominant, operated within institutional constraints. ASEAN's entire diplomatic framework and Southeast Asia's integration into global trade networks reflected confidence that liberal rules would protect smaller states from the whims of great powers. As Washington increasingly signals willingness to abandon these constraints, regional governments must recalculate fundamental assumptions about security and economic stability. Countries like Vietnam, Indonesia, and Malaysia face mounting uncertainty about whether international institutions can genuinely protect their interests or whether future outcomes will depend primarily on raw power relationships.

The Nolan film's Sea Peoples metaphor proves especially apt in illuminating this paradox. The people of Ithaca fear vague, terrifying stories of mysterious raiders from across the sea, constructing an external threat from incomplete information and cultural anxiety. They never recognize that their own sailors, returning from conquest, embody the very danger they dread. This same dynamic increasingly characterizes international perceptions of American behaviour. States that accepted American leadership partly because of institutional frameworks and rule-based constraints now observe that architect selectively dismantling its own creation. The threat to liberal order emerges not from external challengers alone, but from the system's principal architect demonstrating diminishing commitment to its foundational principles.

This unraveling occurs gradually, through incremental deviations that individually might appear justifiable by reference to national security or temporary expedience. Yet cumulatively, these deviations signal a fundamental shift in how American power perceives the relationship between interest and legitimacy. Previous American leaders generally understood that legitimacy derived partly from visible adherence to stated principles, even when costly. Contemporary American statecraft increasingly assumes that power itself provides sufficient justification for policy, with legitimacy treated as a secondary concern. This represents a categorical reversal of the post-war settlement's core logic.

For other nations, particularly mid-sized powers and smaller states attempting to navigate between great powers, the implications prove destabilizing. If the rules truly operate only when convenient for the powerful, then smaller states must adapt strategies accordingly. Rather than investing in institutional competence and rules-based participation, rational strategic calculation points toward cultivating patron relationships with multiple great powers, acquiring advanced military capabilities, and developing regional economic alternatives. These adaptive behaviours, in turn, further erode the liberal order by reducing commitment to its institutions and norms.

The broader historical pattern that The Odyssey illuminates suggests that the greatest threats to an international order rarely originate entirely from external challengers. More frequently, decay begins when those entrusted with maintaining the system gradually reinterpret its principles to serve immediate interests, ultimately resembling the very forces the order was constructed to prevent. The post-war liberal system was explicitly designed to constrain powerful states from exercising unchecked dominion. Yet if its chief architect increasingly treats those constraints as optional, the entire structure loses coherence and attractiveness to other participants.

Southeast Asian policymakers must grapple with this uncomfortable trajectory. The region benefited substantially from American security guarantees and the open international trading system that American power underpinned. However, that arrangement depended on American commitment to rules that limited its own freedom of action. As that commitment erodes, regional states must develop strategies less dependent on American institutional leadership and more focused on diversified partnerships and economic resilience. This adjustment process, while strategically necessary, represents a genuinely lamentable outcome—the unforced squandering of a system that, whatever its imperfections, delivered unprecedented prosperity and stability across much of the world.

Nolan's film ultimately poses a question that modern international relations increasingly must address: Can a liberal order survive its architect's willingness to transcend it? History suggests the answer is no, but the transition toward alternatives remains painfully uncertain, particularly for smaller nations lacking the capabilities of great powers. The Sea Peoples metaphor reminds us that civilizations often fail to recognize when internal transformation converts their protectors into threats, a lesson with uncomfortable relevance to contemporary international politics.
