Since the beginning of the war in Ukraine, the world has witnessed one of the greatest geopolitical upheavals of the 21st century. The stakes go far beyond the fate of Ukraine or the future of Russia. For the United States, the conflict has become a testing ground for its ability to defend the international order shaped after 1945 and reinforced after the end of the Cold War.
Despite unprecedented sanctions on Moscow, massive military support for Kyiv, and a revitalized NATO, the war has not evolved in the direction many Western analysts initially expected. Russia has not collapsed economically, its military industry continues to grow, and—most importantly—the conflict has produced an unexpected consequence: a deepening strategic partnership between Russia and China that is reshaping the geopolitical landscape of Eurasia.
This raises a crucial question: what will the United States do if its strategy in Ukraine fails to significantly weaken Russia?
A hypothesis increasingly discussed in diplomatic and academic circles is that Washington—recognizing China as the primary long-term challenger—may attempt a gradual rapprochement with Moscow to weaken or break the emerging axis between the two Asian powers.
This scenario may seem improbable today, but becomes far more plausible when examined through the lens of strategic interests rather than political rhetoric. In geopolitics, interests always prevail over sentiments. And, as we will see, America’s core interests could eventually push Washington toward a radical recalibration of its global strategy.
1. China’s Rise as America’s Primary Strategic Challenge
To understand why the United States might consider seeking improved relations with Russia, we must begin with a fundamental reality: China is now the principal strategic rival of the United States. This challenge surpasses the Russian threat in every major dimension: economic strength, technological capacity, demographic weight, industrial scale, and global ambition.
China is the only country that possesses simultaneously:
-
the demographic mass to sustain a global power,
-
an industrial base larger than that of the West,
-
a long-term strategic vision,
-
an economy capable of rivaling the United States,
-
and an expanding military with global reach.
For Washington, China represents the most significant systemic threat since the Cold War. Therefore, the entire U.S. strategic architecture of the 21st century revolves around containing China’s rise.
In this framework, Russia—despite its large nuclear arsenal and disruptive potential—remains a regional power with limited economic influence compared to China. The United States faces a hard truth: it cannot fight two strategic competitions simultaneously, one against Russia in Europe and one against China in the Indo-Pacific.
China must remain the top priority.
And this is where the Ukraine conflict complicates the American grand strategy.
2. The War in Ukraine and Its Unintended Consequence: A Stronger Russia–China Alignment
The war and subsequent Western sanctions isolated Russia from Europe, cutting it off from markets, technologies and investments. Predictably, Moscow turned to the only major power capable of supporting its economy and military production: China.
The result was faster and deeper than anticipated.
Today, Russia and China enjoy a level of strategic coordination unseen even during the early Cold War Sino-Soviet alliance. China is now Russia’s leading trading partner; Russia is China’s energy lifeline and a key supplier of military-related technology and raw materials.
The partnership is not merely economic but geopolitical, diplomatic and ideological. Both present themselves as defenders of a “multipolar world” against Western dominance.
For the United States, this is a major strategic setback. No U.S. policy aimed at containing China can succeed if Beijing can rely on Russia as a secure geopolitical and energy partner.
This is the first major reason Washington might consider a future rapprochement with Moscow: to weaken China by disrupting the Eurasian bloc forming under its leadership.
3. If the U.S. Strategy in Ukraine Fails, Washington Must Recalculate
The U.S. approach to Ukraine aimed—explicitly or implicitly—at several goals: support Kyiv, contain Russia, weaken its military capabilities, isolate Moscow economically, and possibly pave the way for political change in the Kremlin.
Years later, the scenario looks more complex than expected.
Russia has not collapsed. Its military industry is growing, its energy exports remain strong thanks to Asia, and China has effectively compensated for many of the losses imposed by Western sanctions.
If this dynamic continues, Washington will face a strategic crossroads:
continue a costly war of attrition without achieving decisive results, or reorient its grand strategy toward its true strategic priority—China.
In this context, the failure to weaken Russia in Ukraine could push U.S. policymakers to consider an audacious move: attempt to peel Russia away from China.
4. Nixon and Kissinger’s Triangular Diplomacy: A Useful Historical Precedent
International relations offer many examples of bold strategic shifts when vital interests are at stake. The most famous is Nixon’s 1972 visit to China. At the time, the United States was locked in a dangerous rivalry with the Soviet Union. Yet Washington chose to open relations with Mao’s China—once seen as an ideological enemy—to weaken Moscow and divide the communist bloc.
That decision changed the course of the Cold War.
It demonstrated that strategic interests always outweigh ideological confrontations.
Today’s situation mirrors the past in a reversed form:
At that time, China was the instrument to weaken the USSR.
Today, Russia could become a tool—if not a partner—to contain China.
5. The U.S.–Russia–China Triangle: The Key to the Future of Global Power
The global order is always shaped by triangular relations among major powers. No dominant nation can allow two rivals to unite against it. One of the core principles of geopolitical realism is to prevent the formation of hostile alliances.
During the Cold War, the United States feared a China–USSR alliance and acted quickly to split them.
Today, the roles are reversed: China is the main rival, and Russia is its crucial partner.
If Moscow and Beijing remain aligned, Asia—and potentially the entire Eurasian continent—could be dominated by a bloc hostile to American interests. Washington knows it cannot allow this outcome.
6. Why a U.S.–Russia Rapprochement Is Strategically Plausible
Why would the United States even consider rapprochement after years of confrontation?
First, to strategically weaken China by depriving it of its most important geopolitical ally. A Russia less dependent on Beijing would slow China’s military and economic expansion.
Second, to influence global energy flows. China’s industrial power relies heavily on Russian oil, gas and coal. Disrupting or reducing this dependency would make Beijing more vulnerable.
Third, a Russia that is less isolated and less reliant on China might be open to cooperation on nuclear security, arms control and stability in volatile regions.
Finally, improved U.S.–Russia relations would allow Washington to reduce its strategic commitments in Europe and redirect resources toward the Indo-Pacific, where China is rapidly expanding its influence.
7. Why Russia Might Also Consider a Future Understanding with Washington
Russia, although strengthened in some areas, is increasingly dependent on China. Over time, this asymmetry may become problematic for Moscow. China’s demographic weight, industrial superiority and global economic reach could eventually allow Beijing to dominate the relationship.
A limited rapprochement with the United States would give Russia strategic breathing room and greater autonomy in its foreign policy. It wouldn’t mean abandoning China, but it could allow Moscow to balance its partnerships and avoid overdependence on a single ally.
8. Obstacles and Challenges to a U.S.–Russia Rapprochement
A thaw in relations would not come easily. The war in Ukraine has left deep political scars. The United States would face resistance from Congress, NATO allies and public opinion. Russia, in turn, would weigh the risks of alienating China, its most reliable partner during sanctions.
Nevertheless, history shows that when the strategic environment changes, even entrenched positions can shift.
Conclusion: The Return of Realism in American Strategy
If the U.S. strategy in Ukraine fails to decisively weaken Russia, Washington may be forced to reassess its priorities. And the primary long-term priority remains the competition with China.
In such a scenario, a rapprochement with Russia would not reflect a moral or ideological shift. It would be a realist calculation driven by one fundamental objective: preventing China from becoming too powerful and from relying on a stable Eurasian alliance.
The United States has made bold strategic choices in the past when global power balances required it. It may do so again in the future—if circumstances push it in that direction.
