A polycentric world

While the discourse regarding a “new world order” has yielded certain insights, it remains largely premature. To be sure, the post-Cold War unipolar moment has passed, as has the global hegemony of U.S. liberal democracy. A polycentric reality—often erroneously labeled “multipolarity”—is already upon us. Yet, it lacks a foundational order to underpin it; instead, the international system is defined by intense rivalry across multiple strata. We are unequivocally in a state of transition. It will take time for these competing powers to accommodate themselves to a new global distribution of power and establish a successor order. Until such an equilibrium is reached, contestation will prevail—ideally without precipitating global catastrophe.

In the current constellation of major powers, the United States and China emerge as the preeminent titans. However, their dynamic differs markedly from that of the previous superpower duality: the standoff between the United States and the Soviet Union. Furthermore, the complex Sino-American relationship exerts a substantially less totalizing influence on the contemporary world system than did the Soviet-American conflict during the Cold War. Anticipating the pathways toward a new order requires analyzing the strategies of several key actors, including major powers such as Russia and India, as well as critical regional players across the globe.

America’s World Revolution

Although the United States may trail in purchasing power parity (PPP), it remains the world’s preeminent power. To write its obituary would be premature: Washington retains decisive material advantages in technology, finance, and non-nuclear military capabilities over all potential rivals. Moreover, during President Trump’s second term, the United States has shifted onto the strategic counter-offensive to arrest the erosion of its primacy. Trump’s objective is unambiguous: to consolidate American strengths, optimize partnerships, and dismantle the ideological, legal, and conventional constraints that inhibit the exercise of U.S. power.

Strengthening this foundation requires revitalizing American technological supremacy and restoring the industrial base, particularly in defense manufacturing. It also entails reasserting the Western Hemisphere as an exclusive sphere of U.S. influence. A “Trump Corollary” to the Monroe Doctrine, initially signaled in Panama, has been operationalized in Venezuela, applied to Greenland, and leveraged to pressure Cuba, Colombia, and Nicaragua. Canada, too, has been put on notice. However, this focus on the “near abroad” does not imply a withdrawal from the world. Rather, it signifies that while the United States refuses to de-globalize its foreign policy, it simultaneously refuses to recognize the spheres of influence of other major powers. The United States remains, in its own view, exceptional.

The optimization of alliances marks a departure from the Cold War consensus; Washington no longer views servicing the international order in the name of democracy as being in its interest. Instead, the United States is determined to transform its alliance network into a tributary asset. Paraphrasing John F. Kennedy, Trump’s message to Europeans and Canadians is stark: “Ask not what America can do for you, but do what America tells you to do.” This shift has already yielded consequences. It began with the burden-shifting of military expenditures, broadened to the imposition of tariffs on partners, and escalated to pressuring an ally to cede the world’s largest island to U.S. control.

Consequently, while NATO persists institutionally, the credibility of the U.S. security guarantee has effectively evaporated, rendering further enlargement moot. The European Union—initially the economic pillar of the trans-Atlantic relationship but later a competitor—has lost American patronage. Washington has no desire for a “single telephone number” to call Europe; on the contrary, a fragmented Europe of nation-states serves U.S. interests far better. Trump has little patience for what he perceives as the EU’s ideological excesses or climate agenda. Instead, he expects European powers to pool their technological assets with America, rearm to form a bulwark against Russia—thereby freeing U.S. forces for priority theaters—and fully back Washington in the economic and technological race against China.

In the Middle East, a region that consumed American attention for decades, Trump is emboldened by U.S. energy self-sufficiency. He seeks to architect and preside over a regional balance among U.S. allies—Israel, Turkey, and the Arab states. The Abraham Accords offer a framework for this goal, and the arrangement regarding Gaza is intended to contain the Palestinian question. Unresolved variables remain, of course: Hamas is battered but not eliminated; Hezbollah is degraded but not neutered; and Iran persists. Trump undertook what no prior president dared—striking Iran’s nuclear program—but despite U.S.-Israeli claims of success, the issue is not fully foreclosed.

Despite Trump’s professed admiration for strongmen like Chinese President Xi Jinping and Russian President Vladimir Putin, he clearly views China and Russia as adversaries. Regarding China, the overriding goal is to thwart Beijing’s economic and technological challenge, which threatens to displace the United States as the global hegemon. To this end, Trump is prepared to compel European and Asian allies to share critical assets with the United States and to align them in pressuring Beijing to reduce its footprint globally—from the Arctic to Africa, and South America to Southeast Asia. Simultaneously, he aims to fortify the “first island chain” defense in the Western Pacific, linking Japan, South Korea, Taiwan, and the Philippines.

For the time being, Trump’s America does not seek direct confrontation with China, either economic or military. Washington requires time to reorganize its domestic base and alliance structure. Thus, it is willing to observe a temporary truce. Yet, the understanding reached between Trump and Xi in Busan is fragile; both sides recognize it as a strategic pause rather than a lasting settlement.

Regarding Russia, Trump’s strategy appears to be one of delegation: pushing Europe to the frontline to contain Moscow. This allows the United States to reduce the risk of direct nuclear escalation and reallocate resources toward China. A Europe locked in an adversarial posture toward Russia serves the dual U.S. interest of weakening a major economic competitor (the EU) and a historical geopolitical rival (Russia). While the Trump administration does not view Russia as a peer threat, it seeks to erode the Sino-Russian entente. This aligns with a broader pattern of disrupting any multilateral compacts that challenge U.S. primacy, most notably the BRICS forum.

China’s Global Ambitions

China stands as America’s principal challenger. Its rapid ascendance since the late 1970s has been the primary driver behind the eclipse of the Western-dominated global order. Beijing aims to assume a central position in this emerging multipolar landscape, leveraging its economic and demographic weight, its status as a civilization-state with uninterrupted continuity, and its confidence in its specific values and organizational model. Operating under the conviction that time is on its side, Beijing expects to ascend to this position gradually and peacefully. While nominally communist, China behaves as a conservative, rather than revolutionary, actor regarding the structure of the international order.

As a result, the world’s largest economy remains more of a geoeconomic and technological power than a geopolitical one. Despite a recent uptick in international activism, China continues to prioritize domestic stability over foreign entanglements. On the global stage, it projects itself as a reformist power seeking to modify, rather than overthrow, the existing system. Beijing retains a major stake in preserving the architecture of the post-Cold War order, from which it has drawn immense benefit over the past three decades. Accordingly, Chairman Xi has introduced a succession of global governance initiatives, seeking to salvage the remnants of globalization and reorient them to China’s advantage.

Beijing does not position itself as the leader of a formal non-Western bloc. It has carefully cultivated a stance of “neutrality” regarding the Ukraine conflict, though its strategic leanings toward Moscow are evident. China has responded with notable restraint to the joint U.S.-Israeli air campaign against Iran, as well as to the U.S. capture of the Venezuelan president—an event that dealt a severe blow to Beijing’s economic interests in Latin America. While China effectively retaliated against Trump’s tariffs by halting rare-earth exports, it has demonstrated little appetite for further escalation.

Nevertheless, the Chinese leadership views a strategic confrontation with the United States as inevitable and is preparing accordingly. China is aggressively expanding its military capabilities across both nuclear and conventional domains. It appears poised to achieve rough parity in strategic nuclear systems with the United States (and, by extension, Russia). The September 2025 Victory Day parade, commemorating the defeat of militaristic Japan, served as a deliberate showcase of this growing military muscle.

Diplomatically, China is deepening its ties with Russia, its only major-power partner. This relationship is not a classical alliance, let alone a formal bloc, but rather a strategic alignment grounded in shared interests and convergent worldviews. While Beijing’s foreign and security policies have globalized, their center of gravity remains squarely in its near abroad: Taiwan and the South China Sea—which China regards as sovereign territory—as well as Northeast, Southeast, and Central Asia. Although Beijing comments on all major global issues, it remains reluctant to be drawn into conflicts in distant theaters, such as Venezuela or Iran.

Russia’s Eurasian Pivot

As the world’s fourth-largest economy in PPP terms, Russia has re-emerged as a major power following the tumultuous transition that succeeded the collapse of the Soviet Union. Since initiating its military operation in Ukraine in 2022, the country has undergone a profound domestic transformation—a process accelerated by the more than 30,000 sanctions imposed by the United States, Europe, Japan, and other Western-aligned nations. In responding to this unprecedented economic pressure, Russia has demonstrated a degree of resilience and adaptability that has confounded many observers.

The reclaiming of “full sovereignty” from the U.S.-led West is touted by the Kremlin as the crowning achievement of recent years. The geopolitical implications of this rupture are fundamental. The vision of a “Europe from Lisbon to Vladivostok” has been consigned to history. While European capitals have sought to isolate Russia, Moscow has proactively redefined itself as a distinct civilization-state, effectively concluding a three-century epoch of European orientation. Consequently, Russia’s geoeconomic and geopolitical axes have pivoted sharply toward the East and the South, with a growing strategic discourse advocating the transfer of the country’s center of gravity to Siberia.

Confronting a hostile West engaged in a proxy war in Ukraine, Moscow has intensified its engagement with Asia, Africa, and Latin America—the so-called “World Majority.” It relies heavily on strategic partnerships with China and India, as well as pragmatic relations with Turkey and the Gulf States. Concurrently, Russia seeks to bolster non-Western multilateral institutions, chiefly the BRICS and the Shanghai Cooperation Organization (SCO). Moving beyond its late twentieth-century focus on European security architecture, Moscow is now advancing a Eurasian security framework, centered on Asian stakeholders.

Casting aside the liberal paradigm of the 1990s, Russia has embraced traditional values rooted in Orthodox Christianity, Islam, and the country’s other historic confessions. While traditionalist at home, Russia acts as a revisionist power abroad: an unabashed critic of Western universalism and American imperialism, and a patron to regimes resisting Western pressure.

Entrenched in a protracted conflict in Ukraine, Russia is aggressively reconstituting its military capabilities and defense industrial base. The leadership has adopted a mobilized posture, anticipating a long-term struggle that will extend well beyond the current theater in Ukraine. A standoff with Europe is expected to persist for years. Yet, despite its projection of solidity and defiance, Russia faces acute structural headwinds: sluggish economic growth, the lingering legacy of post-Soviet de-industrialization, and a deepening demographic crisis.

Divergent Paths in a Polycentric World

India, the world’s most populous nation and third-largest economy, is rapidly ascending as a global power. Mirroring China, its strategic objective appears to be the restoration of its historical primacy within the global hierarchy. For the present, New Delhi maintains an intricate diplomatic equilibrium: soliciting investment and technology from the United States; managing a complex relationship with China—simultaneously a competitor, economic partner, and neighbor across a contested border; and sustaining ties with Russia, a historical ally and traditional supplier of military hardware.

India is an active participant in the Quad alongside the United States, Australia, and Japan, while simultaneously holding membership in the BRICS and the SCO. Eschewing traditional non-alignment in favor of a proactive “multi-alignment,” contemporary India engages deeply with powers that view one another as adversaries. For New Delhi, the paramount imperative remains domestic modernization: economic expansion, social uplift, and technological advancement.

To date, Indian leadership has navigated this geopolitical tightrope with notable dexterity. As a civilization-state standing alongside the United States, China, and Russia, India constitutes the fourth pillar of the twenty-first-century power structure. Its geopolitical clout, once constrained, is expanding in tandem with its rapid economic growth. India is poised to assume a natural leadership role across the Indian Ocean littoral, the Middle East, East Africa, and Southeast Asia.

Paradoxically, India’s most acute challenges reside within its immediate periphery. Relations with Pakistan, a fellow nuclear-armed state, remain volatile and prone to escalation, notwithstanding their shared SCO membership. Similarly, ties with Bangladesh have grown strained. Nevertheless, having shed its historic reticence and driven by the formidable ambitions of its elite, India possesses the requisite elements to solidify its status among the world’s apex powers in the decades ahead.

As the broader Western order undergoes a painful restructuring, Europe—a primary beneficiary of post-Cold War globalization—has emerged as a principal casualty. While the continent faces severe external headwinds, the bulk of its malaise is homegrown, stemming from the strains of migration, the economic costs of the green transition, and chronic regulatory sclerosis. Yet, the external challenges are equally acute.

Across the Atlantic, the United States now challenges Europe on every front: from ideology and economics to domestic politics and grand strategy. Closer to its borders, Europe’s strategic miscalculations regarding Russia—most visibly, but not exclusively, in Ukraine—have precipitated security dilemmas and economic dislocations that would have been inconceivable merely a few years ago. Afflicted by a vacuum of leadership, strategic myopia, and a consequent paralysis of will, Europe’s trajectory is darkening. While the future of the European Union remains indeterminate, the continent’s global influence is eroding at a precipitous pace.

In stark contrast to Europe, Japan—the world’s fifth-largest economy—has retained a cohesive strategic identity. Since its defeat in World War II, Tokyo has operated within the American security orbit, yet it has simultaneously hedged its strategic exposure by steadily fortifying its indigenous military capabilities. Over the past two decades, Japan has incrementally reinterpreted the constitutional constraints governing the use of force. Moreover, it possesses the technical threshold to rapidly develop an independent nuclear deterrent, should the need arise.

Japan is actively hardening its defenses for a potential confrontation with China; yet, given the realities of geography and demographics, Tokyo recognizes that it cannot sustain a high-intensity conflict with its giant neighbor. Hence, Japan’s long-term trajectory likely points toward a progressive reduction in its strategic dependence on the United States. Tokyo remains resolutely opposed to absorption into a Sinocentric sphere of influence. Its grand strategy, therefore, rests on safeguarding sovereignty through enhanced national power and a diversified network of great-power relationships.

The Rise of Regional Orders

Beyond the great powers, a cadre of nations has recently elevated their international profiles, acting as regional poles of influence. Under President Erdoğan, Turkey has sought to revitalize the geopolitical legacy of the Ottoman Empire while simultaneously cultivating a pan-Turkic sphere. The former is evident in Ankara’s interventions across Iraq, Syria, Libya, and Gaza; the latter is manifested in its deepening strategic bond with Azerbaijan, its growing footprint in Armenia, and its expanding ties to the Turkic nations of Central Asia.

Leveraging robust U.S. support, Israel is forcibly reshaping the Middle East: establishing security buffer zones along its borders, attempting to neutralize the Iranian threat, and pursuing normalization with Arab states.

Within the Arab world, Saudi Arabia has emerged as the preeminent state, effectively supplanting Egypt’s historical leadership. Beyond its status as the custodian of Islam’s holiest sites and a hydrocarbon titan, the Kingdom is leveraging its vast financial reserves to project hard power. Notably, the potential for a military alignment with nuclear-armed Pakistan could fundamentally alter the region’s strategic calculus.

Iran, heir to one of the world’s most enduring civilizations, remains an indelible force. Irrespective of its internal political trajectory or the fluctuations in its relations with Washington, Tel Aviv, or Riyadh, Tehran will remain a central actor in this highly competitive theater. As U.S. hegemony in the Middle East recedes, Iran—alongside Turkey, Israel, and Saudi Arabia—will lock into a contest to define a regional balance of power that aligns with its interests.

The Middle East serves merely as a microcosm for a broader phenomenon: a “second tier” of order-making in the nascent geopolitical landscape. From Brazil and Argentina to Indonesia and Vietnam, and South Africa to Nigeria, rising powers are carving out regional and sub-regional orders. This fragmentation extends beyond geopolitics into domains such as artificial intelligence, energy, finance, and water resources—each field destined to have its own champions and fierce competition.

Wherever one looks, this process of order-making will be tumultuous. While not every nation can afford—or will adopt—the unvarnished “might is right” approach of the current U.S. administration, international law and multilateral institutions will inevitably suffer. Entities like the United Nations will endure as forums for dialogue, but not as arbiters of decision-making.

The UN was the architectural product of the global transformation following World War II. The current systemic crisis is its functional analogue—mercifully, with fewer casualties thus far. Only when this crisis has run its course and a new equilibrium settles will new—or fundamentally reformed—institutions emerge to govern it. In 2026, however, that horizon remains distant.
