“Never interrupt your enemy when he is making a mistake.”
Napoleon Bonaparte’s maxim may well have been in the minds of policymakers in Moscow and Beijing these past weeks, as the US war in Iran dragged on.
And now that a 14-day ceasefire between Tehran and Washington is in effect – with both sides claiming “victory” – Russian and Chinese leaders still have an opportunity to profit from what many see as America’s latest folly in the Middle East.
Throughout the weekslong conflict, China and Russia struck a delicate balance. Both declined to give Iran – seen to a varying degree as an ally of both nations – their full-throated support or sink any real costs into the conflict.
Instead, they opted for limited assistance in the form of small-scale intelligence and diplomatic support.
As a scholar of international security and great power politics I believe that is for good reason. Beijing and Moscow were fully aware that Iran could not “win” against the combined military might of the US and Israel. Rather, Iran just needed to survive to serve the interests of Washington’s main geopolitical rivals.
Below are four ways in which the US war in Iran has damaged Washington’s position in the great power rivalries of the 21st century.
1. Losing the influence war in the Middle East
As I explore in my book “Defending Frenemies,” the US has long struggled to balance competing objectives in the Middle East. During the Cold War, this meant limiting the Soviet Union’s influence in the region, while contending with the development of nuclear weapons by two troublesome allies, Israel and Pakistan.
By the 2020s, the priorities in Washington were aimed at restricting the influence of the US’s great power rivals – China and to a lesser degree Russia – in the Middle East.
Yet under Presidents Xi Jinping and Vladimir Putin, China and Russia have sought to increase their footprint in the region through a variety of formal alliances and informal measures.
For Russia, this took the form of aligning with Iran, while also partnering with Tehran to prop up the now-ousted regime of President Bashar Assad during the Syrian civil war. Meanwhile, China increased its diplomatic profile in the Middle East, notably by acting as a mediator as Saudi Arabia and Iran restored diplomatic ties in 2023.
The irony of the latest Iran war is that it follows a period in which circumstances were unfavorable to Russian and Chinese aims of increasing their influence in the Middle East.
The fall of Assad in December 2024 deprived Russia of its one reliable ally in the region. And Trump’s May 2025 tour of the Gulf states, in which he secured major technology and economic deals with Saudi Arabia, the United Arab Emirates, Qatar and Bahrain, was aimed at countering China’s growing economic and diplomatic influence in those countries.
With Washington perceived as an increasingly unreliable protector, the Gulf states may seek greater security and economic cooperation elsewhere.
2. Taking US eyes off other strategic goals
In expanding military, diplomatic and economic ties in the Middle East, Russia and China over the past two decades were exploiting a desire by Washington to move its assets and attention away from the region following two costly wars in Iraq and Afghanistan.
Trump’s decision to wage war against Iran directly contradicts the national security strategy his administration released in November 2025. According to the strategy, the administration would prioritize the Western Hemisphere and the Indo-Pacific, while the Middle East’s importance “will recede.”
In co-launching a war in Tehran with Israel, without any prior consultation with Washington’s other allies, Trump has shown a complete disregard for their strategic and economic concerns. NATO, already riven by Trump’s repeated threats to the alliance and designs on Greenland, has now shown further signs of internal divisions.
That offers benefits for China and Russia, which have long sought to capitalize on cracks between America and its allies.
The irony, again, is that the war in Iran came as Trump’s vision of the US as the hegemonic power in the Western Hemisphere was making advances. International law and legitimacy concerns aside, Washington had ousted a thorn in its side with Nicolás Maduro in Venezuela and replaced him with a more compliant leader.
3. Disproportionate economic fallout
Iran’s closure of the Strait of Hormuz, where some 20% of the world’s oil passes, was as predictable as it was destructive for US interests.
But for Russia, this meant higher oil prices that boosted its war economy. It also led to the temporary but ongoing easing of US sanctions, which has provided Moscow an indispensable lifeline after years of economic pressure over the war in Ukraine.
While a prolonged closure and extensive damage to oil and natural gas infrastructure in Iran and the Gulf states no doubt hurts China’s energy security and economy, these were risks Xi appears willing to accept, at least for a time.
And by building up a domestic oil reserve and diversifying energy sources to include solar, electric batteries and coal, China is far better positioned to weather a prolonged global energy crisis than the US.
Indeed, Beijing has made strides in recent year to encourage domestic consumption as a source of economic growth, rather than be so reliant on global trade. That may have given China some protection during the global economic shock caused by the Iran war, as well as push the economy further down its own track.
The more the US loses control over events in the strait, the more it loses influence in the region – especially as Iran appears to be placing restrictions on ships from unfriendly nations.
4. Loss of global leadership
Trump’s willingness to abandon talks to go to war, and the contradictory rhetoric he has employed throughout the Iran conflict, has weakened the perception of the US as an honest broker.
That provides a massive soft power boost for Beijing. It was China that pressed Iran to accept the 14-day ceasefire proposal brokered by Pakistan. Indeed, China has slowly chipped away at America’s longtime status as global mediator of first resort.
Beijing has successfully mediated in the past between Iran and Saudi Arabia, and it attempted to do the same with Russia and Ukraine and Israel and the Palestinians.
In general, the Iran war adds weight to Beijing’s worldview that the US-led liberal international order is over. Even if China benefited at some level from the war continuing, its decision to help broker the ceasefire shows that China is increasingly taking on the mantle of global leadership that the US used to own.
And for Russia, the Iran war and the rupture between Trump and America’s NATO allies over their lack of support for it, shift world attention and US involvement from the war in Ukraine.
