There was no formal rupture. No summit. No declaration that the old order had ended.

In March 2023, Saudi Arabia and Iran agreed to restore diplomatic relations in a deal announced in Beijing. China did not create every channel that led there, but it hosted the breakthrough and claimed the diplomatic win. For most of the postwar era, a move of that symbolic weight in the Gulf would have run through Washington. This time it did not. The choice made the point.

They show up first in procurement, financing and diplomatic routing.

The world did not organise itself around America because everyone believed in American virtue. Plenty never did. What mattered was something more practical: for a long time, the United States was the system’s most reliable organiser. The dollar sat at the centre of trade and finance because it was liquid and widely accepted. NATO allowed Western Europe to rebuild without fully rearming. American guarantees in Asia gave Japan, South Korea and Taiwan space to industrialise under a stable security umbrella.

None of this was altruism. It was power organised in ways others could use.

The world did not need to trust American motives. It needed to trust that America would broadly keep the system running. For decades, that was enough.

The erosion did not begin in 2017. That version is too flattering to everyone involved.

Iraq in 2003 was a first major breach. The damage was not that America used force. It was that it did so without a new UN mandate, on intelligence that collapsed, and then failed to control the aftermath. The financial crisis of 2008 deepened the doubt. A shock rooted in American finance spread through the global system, damaging banks and pension funds far beyond the United States. Countries long lectured on prudence watched the supposed centre of competence export instability at scale.

Then came another sequence: the TPP abandoned before ratification, Afghanistan ended in a manner that left allies scrambling. Each decision had its own rationale. Together, they suggested something harder to price: discontinuity.

There is a harder criticism worth taking seriously. For much of the world outside the West, the complaint is not that America became less trustworthy. It is that America became less careful about disguising what it always was. The rules-based order, in this reading, was American interest in universal language. Washington defended sovereignty selectively, praised open markets selectively, enforced non-proliferation selectively.

That criticism has force. But it misses something.

Even selective consistency has value. When the United States worked through institutions it had designed, accepted some procedural limits and maintained a recognisable strategic logic from one administration to the next, it produced something real. Smaller states could plan around it. Adversaries could infer its boundaries. States do not build around virtue. They build around continuity.

What is happening now is not a dramatic global revolt. It is quieter than that, and probably more lasting.

Europe is rearming at a pace that would have seemed politically impossible five years ago. The ReArm Europe plan aims to mobilise €800 billion in defence spending, including €150 billion in SAFE loans for joint procurement. That is not anti-Americanism. It is what systems do when dependence starts to look like concentration risk.

The Gulf is adjusting too, though more narrowly than the headlines suggest. CENTCOM remains in Qatar. American forces remain in the UAE and Kuwait. The security architecture has not moved. What has moved is the diplomatic and commercial layer above it: the China-brokered Saudi-Iran normalisation, broader Gulf engagement with Beijing, and a growing willingness to build forums and channels that do not run automatically through Washington. The base stays. The monopoly on attention does not. It is not defection, but it is the end of a kind of deference.

The same logic is visible in semiconductors. The US, Europe and north-east Asia are all building domestic chip capacity. Once supply chains are redesigned around redundancy, they tend to outlast any single administration.

America remains the most powerful single actor in the system. Its military has no peer in global power projection. Its capital markets are the deepest in the world. The dollar, despite years of predictions, remains dominant in global reserves.

But power is not the same as reliability.

A powerful but unpredictable partner creates a specific problem: you cannot plan around it. It is difficult to anchor a 30-year industrial strategy, a security doctrine or a reserve structure to a partner whose posture can shift sharply with each domestic political turn.

So the world is not abandoning America. It is asking a more practical question: where does dependence become dangerous? Once that question is asked seriously, governments start building redundancy through new financing mechanisms, dual diplomatic tracks and domestic manufacturing capacity. None of this requires an anti-American doctrine. It only requires repeated exposure to uncertainty.

The issue is not whether America remains powerful. It almost certainly will. The issue is whether power exercised without continuity still constitutes leadership, or whether it becomes another variable others must route around.

That is the change worth watching. By the time Washington starts describing it, much of it may already be embedded in other people’s systems: procurement rules, reserve allocations, supply-chain maps, and the quiet assumption that the fixed point is no longer quite fixed.
