The current volatility stretching from the plains of Ukraine to the shores of the Persian Gulf is often viewed as a series of isolated crises. Although, a deeper strategic pattern is emerging—one that suggests the world is witnessing the rise of a concerted “new authoritarian alliance” comprising China, Russia, and Iran. This alignment is not merely a marriage of convenience but a structural attempt to challenge the maritime-led global order that has dominated since 1945.
At the center of this analysis is the perform of Hal Brands, a professor at the Johns Hopkins University School of Advanced International Studies (SAIS). Brands argues that we have entered a “second Eurasian century,” where the struggle for hegemony over the world’s largest landmass—Eurasia—has returned to the forefront of global diplomacy and warfare. By coordinating their efforts, these three powers aim to push the United States and its allies out of the Eurasian interior and its surrounding rimlands.
Eurasia is the ultimate geopolitical prize. Covering more than one-third of the Earth’s land area and housing approximately 70% of the global population, it possesses the vast majority of the world’s industrial capacity and military potential. For the authoritarian regimes in Beijing, Moscow, and Tehran, controlling this space is the key to ending what they perceive as Western hegemony.
The Clash of Continental and Maritime Powers
To understand the current alignment of China, Russia, and Iran, Brands suggests looking back at the 20th century through the lens of “continental authoritarianism.” He posits that the two World Wars were essentially geopolitical struggles between “maritime democracies”—led by the United Kingdom and the United States—and “continental authoritarian powers” seeking to dominate the Eurasian landmass.

During World War I and World War II, the German Empire and later Nazi Germany, alongside Imperial Japan, attempted to leverage Eurasia’s immense resources to establish a global hegemony. The victory of the maritime powers was not just a moral win for democracy, but a strategic success in preventing any single land-based power from controlling the “Heartland” of the continent.
This dynamic persisted into the Cold War. The Soviet Union sought to expand its influence from the center of Eurasia toward the periphery. The United States countered this through a strategy of containment, strengthening bonds with democratic nations on the edges of the continent. This “rimland” strategy eventually contributed to the internal collapse of the Soviet system, ending the conflict without a direct global thermal war.
The 2022 Pivot and the New Axis
The era of undisputed U.S. Unipolarity has faded, replaced by a more aggressive coordination among authoritarian states. A critical turning point occurred in 2022 with the joint statement between Presidents Vladimir Putin and Xi Jinping, which signaled a “no limits” partnership. This diplomatic alignment was almost immediately followed by Russia’s full-scale invasion of Ukraine, marking a violent attempt to redraw the borders of Eurasian influence.
While Russia pushes from the west and China expands its economic and military footprint across Asia and Africa, Iran serves as the southern anchor of this authoritarian bloc. The strategic synergy is clear: Russia provides military technology and energy, China provides economic lifelines and diplomatic cover, and Iran offers a gateway to influence the volatile Middle East.
This alignment is not without friction. Analysts continue to debate whether China and Russia are true allies or merely strategic partners. For instance, China’s support for Russia in the Ukraine conflict has remained largely economic and diplomatic rather than military. Similarly, the depth of Russian and Chinese support for Iran during periods of high tension with the U.S. Has occasionally been viewed as insufficient, suggesting that national interests still outweigh ideological solidarity.

The Bosphorus Strait remains one of the most critical geopolitical chokepoints, marking the boundary between European and Asian spheres of influence.
The Strategic Calculus of Containment
The U.S. Approach to this new alliance has been fragmented. During his presidency, Donald Trump utilized a “maximum pressure” campaign against Iran, arguing that preventing Iranian nuclearization and inducing regime change were essential for regional stability. However, some geopolitical analysts suggest a secondary motive: by weakening Iran, the U.S. Hoped to sever the growing link between Tehran and Beijing, thereby isolating China’s influence in the Middle East.
The danger, according to Brands, is that if these continental powers are allowed to consolidate their hold over Eurasia, the entire “free world” becomes vulnerable. The strategy for the future relies on nine geopolitical principles, emphasizing that the maritime democracies must remain unified and committed to the periphery of Eurasia to prevent a total authoritarian takeover of the interior.
Geopolitical Stakeholders and Impacts
| Entity | Strategic Goal | Primary Tool |
|---|---|---|
| China | Global hegemony; regional dominance in Asia | Economic investment (BRI), diplomatic leverage |
| Russia | Imperial restoration; control of Eastern Europe | Military force, energy exports |
| Iran | Regional hegemony in Middle East; survival | Proxy networks, asymmetric warfare |
| U.S. & Allies | Maintenance of a rules-based international order | Maritime alliances, sanctions, deterrence |
Implications for the Korean Peninsula
For South Korea, this shift is not an abstract theoretical exercise but an existential challenge. Positioned precisely at the boundary between the continental authoritarian powers and the maritime democratic alliance, Seoul finds itself in a geopolitical vice. The rise of China and the volatility of the Russia-Ukraine and U.S.-Iran conflicts create a ripple effect that directly impacts the security of the Korean Peninsula.
As China seeks to project power beyond its borders, the pressure on South Korea to balance its economic ties with Beijing against its security alliance with Washington continues to intensify. The “Eurasian century” implies that the peninsula will remain a primary flashpoint where the interests of the land-based and sea-based powers collide.
The next critical checkpoints for this unfolding drama will be the upcoming diplomatic summits between the “no limits” partners and the evolving nature of U.S. Security guarantees in the Indo-Pacific. Whether the maritime alliance can maintain its cohesion in the face of internal political divisions will likely determine if the “Heartland” remains open or falls under the control of a new authoritarian axis.
