Why Containing Iran Is a Gift to China

The hook

China has been the recipient of an enormous geopolitical gift from the U.S.--a distraction. A longtime friend of the U.S. (and China!), Pakistan, sits at the head of the mediation table; Trump has bragged of intercepting a Chinese tanker intended as a gift to Iran. reuters.com On the surface this points to a positive development for U.S. hard-power coercion. Meanwhile, China sends material to Iran intelnews.org to help it keep fighting, even as it plays at peacemaker. In addition, the U.S. is busy expending its smartest munitions, fatiguing its carrier groups, and burning through its soft power influence in the region. At the same time, China is able to show the world its peacemaking credentials, all while its gaze shifts to its coast and across the Taiwan Strait to Taiwan. This isn't only about Iran.

The framework — overstretch

Great powers tend to rise and fall in a pattern as Paul Kennedy in Rise and Fall of the Great Powers (1987) describes it. The budding great power benefits from the current power or powers enforcing order in the parts of the world it can touch. If the new power is able to sustain growth, quell the inevitable internal disruptions inherent in any growing nation, and catch a break from its neighbors it can soon begin to assert its power internationally in order to safeguard its interests and acquire new resources and markets (either through trade or invasion). As time goes on the amount of international commitments begins to become a drag on the power as wants become needs, and allies' requests for help become a burden it cannot bear--imperial overstretch.

Why this matters now

How this ends differs, some powers collapse, some fade quietly and remain intact, while others are revitalized. Various events in the past ten years (The China/First and Second Island Chains for example) speak to the fact that the United States seems to be closer to the end of this cycle than the beginning and we don't know where it will land. Every carrier strike group tied up in the Gulf is one not deterring a Chinese move on Taiwan. Every dollar that the U.S. spends on operations in the MENA region takes precious resources away from the Pacific which every administration since President Obama has viewed as the geopolitical pivot point for the future of the United States' global strategy.

What overstretch predicts here

In order to contain Iran, the U.S. is able to use different types of coercion: military, economic, or diplomatic. The U.S. tried all three, recently combining military with severe economic coercion through the weeks-long bombing campaign and the current blockade. Why is the U.S. spending so much money, material, and putting its soldiers in danger? The U.S. is a victim of its own soft imperialism. MENA fell squarely into the U.S. sphere of influence after the end of the Cold War and with the result of the first Persian Gulf War this handed the U.S. a number of security commitments such as Kuwait, the Kurdish nation in the North of Iraq, Saudi Arabia, and Israel. If we take a look at how Gilpin measures a hegemonic power's overstretch and where the U.S. lands, it does not look good for the United States.

The U.S.'s deploying three carrier strike groups, carriers Abraham Lincoln, Gerald Ford and George HW Bush breakingdefense.com, means the U.S. is deprived of one quarter of its carrier force in a region of marginal geostrategic value. In addition, at Hendrix's 2013 estimate of roughly $6.5 million per CSG per day, three CSGs in one theater is a budget commitment as much as a force-posture decision. dtic.mil Two Patriot air-defense battalions have already moved from the Indo-Pacific to the Gulf, and the Carl Vinson is being redirected from the Pacific to CENTCOM on its next deployment. Brown University's Costs of War project Bilmes, October 2025 put the wider Middle East bill since October 2023 at $31.35–$33.77 billion, including direct operations and military aid to Israel through October of 2025 with the latest iteration of the U.S./Iran conflict costing the U.S. between $25-50 billion. reuters.com Even worse news, the U.S. has used up a significant amount of its smart munitions the production of which depends on materials only China can cheaply provide. nytimes.com The benefit to China in the Pacific can't be measured in carrier-days the way the U.S. cost can, but when the dominant power burns capacity in a region, the rising power inherits the residuals — diplomatically, economically, and in regional perception.

What this gets wrong

Mearsheimer's argument that great powers seek only regional hegemony applies here. China seeks dominance in Asia, not the Middle East. The MENA moves can be seen as opportunistic free-riding, not a strategic investment in replacing the US. China's peacemaker role is performative. China lacks the security capability — no carriers, no MENA bases —to actually take over the regional order. However:

"China can have every intention to not get caught up in the MENA region, but super powers don't usually get to make that sort of choice."

China is just as susceptible as any superpower to geopolitical creep as it ties itself to maintaining the world order that favors it. Allies need propping up, resources need protecting and China's MENA commitments will deepen as the U.S.'s influence fades from the region and nations go looking for great power protection. Then China could see itself caught in the same imperial overstretch trap the U.S. is in, but without the same global logistical capabilities the U.S. has built and technological ability that has made the U.S. so successful at influencing events so far from its shores. The point might not be that China is trying to replace the U.S. in the MENA region, but that the US ties ITSELF down trying to retain influence while ignoring the bigger and more important strategic fight in the Pacific.

The takeaway

Most importantly though, the US is hastening the shift of power toward China — not by being replaced in MENA, but by being tied down there. China benefits from US distraction; the EU is forced into divergence; the US's own coercive choices accelerate both China's gains and the EU's divergence from U.S. influence. China's closest South Asian partner since the 1960s, Pakistan, is leading peace talks which signals that the United States is no longer in control of the peace--evidenced by the absence of traditional U.S.-influenced mediators, Egypt and Turkey, who normally would have been more involved or maybe even the United Arab Emirates. stimson.org Less discussed but no less important: the strain on its alliance with the EU/NATO is an underrated cost. euronews.com The more this pattern holds, the more the Atlantic alliance rifts — Europe is being forced into independent foreign policy in MENA and the rest of the world by the same coercive choices. Soon, the U.S. will face a situation where it contends with China in the Pacific without its most powerful allies, with the U.S.'s munitions and treasury depleted, and U.S. soft power no longer able to prop up its relationships to the level it needs to remain atop its superpower perch.

Containing Iran isn't free. Every move in MENA is also a move in the Pacific.
