Strategic Patience and the Balance of Power: What the Iran War Means for China

The phrase often attributed to Napoleon and turned into an adage—“never interrupt your enemy when he is making a mistake”—may offer us a meaningful starting point for understanding China’s silence on the Middle East. Amidst the escalating chaos of the Iran war, China's approach reflects not a passive stance but a "calculated strategy." What are the implications of the Iran war for Beijing?

To provide a detailed answer to this question, it is essential to consider structural issues that go beyond current geopolitical developments. John Mearsheimer’s offensive realism can serve as a theoretical toolset to guide us at this point. According to Mearsheimer, the international system is anarchic, meaning that there is no authority above the states. To recall his classic description, in the brutal world of international politics, if a state gets into trouble, there is no ‘911’ emergency number to call.

According to offensive realism, great powers must maximize their power to survive, and no state can be certain of another state’s intentions. Under these conditions, the most rational strategy is to adopt an approach that erodes the rival’s capacity without engaging in direct conflict with it. In the context of the Iran war, China is pursuing this approach.

In this article, I argue that within the framework of offensive realism, the Iran war has produced three distinct gains for China: the attrition of the hegemon, the reconstruction of the regional balance of power, and the disruption of the alliance architecture.

The Exhausted Hegemon and China’s Strategic Dividend

The weakening of the US’s capacity to contain China due to the Iran war indirectly benefits it. As the US’s naval power, diplomatic efforts, and crisis management capacity become engaged in the Middle East, its focus on the Indo-Pacific is correspondingly eroded. In Iran, China enhances its strategic advantage by exploiting Washington's costly entanglement in the Middle East; therefore, it is possible to say that Beijing is content to watch as the US squanders its own strategic energy in the Middle East.

In light of Paul Kennedy’s observations on great powers, we can observe that the US has become ensnared in the dynamic of imperial overreach. When read together with Mearsheimer and Walt’s offshore balancing line, it is not hard to foresee that China will benefit from the strategic and logistical costs of hegemonic overstretch.

From China’s perspective, the strategic benefit of this situation lies in an acquisition attained without incurring costs. Without deploying a single soldier or firing a single missile, and by passively managing the diplomatic equation alone, Beijing observes the erosion of its main rival’s capacity. From Mearsheimer’s realist framework, great powers accrue relative power not only during the wars they fight but also in moments when others exhaust each other.

Who will fill this regional vacuum?

Another prediction of offensive realism is that the great powers seek regional hegemony. According to Mearsheimer, for a state to rise on a global scale, it must first establish hegemony in its own region and then prevent the rise of hegemonic powers in rival regions. While China openly pursues the goal of regional hegemony in Asia, it is increasingly seeking influence in the Middle East.

The Iran war opened a dual window of opportunity for this pursuit. First, Beijing's role as a “crisis manager,” having mediated the Iran-Saudi Arabia rapprochement, is being reinforced. This may increase China's diplomatic weight in regional reconstruction after the war. Second, and more critically, the United States’ renewed entanglement and attrition in the region undermines Washington's long-term credibility among its Asian allies. Across the arc from Taiwan to the Philippines, and from Japan to South Korea, the following question may become more frequently asked: “Are the US commitments truly reliable, or will we be left alone in a potential crisis?”

According to Mearsheimer’s theory, this is a gain for China. As US deterrence power in the Indo-Pacific weakens, regional states may begin to display a “bandwagoning” tendency. This would result in regional countries aligning themselves with China’s interests. It may also trigger risk avoidance (hedging) and limited alignment strategies among certain actors.

The Alliance Architecture Is Under Strain

Mearsheimer’s offensive realism treats alliances as situational tools that states resort to in the anarchic international system according to power balances and threat perceptions. From this perspective, alliances are shaped not by shared values but by shifting power calculations, security concerns and cost-benefit assessments. Therefore, as states’ threat perceptions and priority interests change, alliance architectures also undergo transformations. The Iran war can be interpreted as a critical turning point that tests the US-led alliance order precisely in this regard.

NATO allies in Europe are clearly uneasy about being drawn into a new Middle Eastern front, with Ukraine fatigue yet to subside. The Gulf monarchies are compelled to side with the US—even at the expense of reversing previous steps toward normalization with Iran—because the region’s security architecture is built around the US military presence. The foreign policies of these states, which follow a risk-averse line in the US-China rivalry, are in chaotic turmoil.

This disruption in the alliance architecture shaped by the US gives tangible ground to China’s narrative of building an “alternative, multipolar, just order.” In the logic of offensive realism, every crack in the alliance system becomes an opening that the rising power can use to expand its sphere of influence. Moreover, Beijing secures this opening not through its own intervention but as a result of Washington’s unrelated military intervention.

Let us not forget that in the 20th century, the US joined both world wars relatively late and built its hegemony on strategic patience. China is the strategic wait-and-see power of the twenty-first century. On the other hand, offensive realism also shows us that, no matter how calculated the great powers may be, they cannot be fully protected from the anarchic nature of the international system. Every point that Beijing thinks it has scored today may be squandered tomorrow in another crisis.
