Beijing’s readout of last month’s Trump–Xi summit contained a phrase easy to miss and hard to overstate. The two leaders, Xi said, had agreed to build “a constructive China–US relationship of strategic stability” — a framework Beijing intends to treat as the lodestar for the next three years and beyond (Source). Washington arrived chasing commercial wins; Beijing arrived prepared to recast the relationship itself (Source). The language is studiously bland. The signal is not.
The timing was not incidental. The summit unfolded in the middle of a war. Since late February, US and Israeli strikes had killed Iran’s supreme leader, and Tehran’s throttling of the Strait of Hormuz — the channel for roughly a fifth of the world’s seaborne oil — had driven crude above $110 a barrel and US petrol past $4 a gallon (Source). For weeks Trump had leaned on Beijing to help reopen the strait, even dangling a delay of the trip to force the issue (Source). Here the hawks’ blind spot shows most plainly: were the confrontation to pull China onto Iran’s side, the path from a regional war to a great-power one would stop being hypothetical.
What Beijing’s strategists appear to have grasped, and what many China hawks in Washington and Brussels still resist, is that a full-spectrum economic, technological and military confrontation between the two powers has no safe exit. The worst case is not a stalemate. It is escalation that ends in nuclear use — fought, in the final reckoning, over little more than ideology.
To an American ear, “strategic stability” carries a precise Cold War freight: each side exposed to the other’s retaliation, a second strike that survives a first, open lines between capitals, verification, treaties that cap arsenals, and the harder modern questions of missile defence, space, cyber and artificial intelligence. Washington can absorb the phrase without friction because it already occupies a fixed berth in American thinking, where it tends to be treated as an engineering problem — stand up the channels, agree the red lines, sign the document. In Chinese usage the same words run broader. A substantial body of Chinese officials and analysts stretches “strategic stability” past the nuclear question toward the general health of great-power relations. The two sides have agreed on a phrase; they have not agreed on what it means.
That gap is not new; only the actors have changed. The Biden administration called the contest “competition” and spent four years trying to bolt “guardrails” onto it. Beijing has now supplied the more operational language — managed rivalry inside a fixed frame — while Washington came with a deal-sheet and no comparable account of what the relationship actually is. On the first-order question, Beijing is writing the vocabulary and Washington is borrowing it (Source).
The temptation is to treat this as semantics. It is not. The reason to take “strategic stability” seriously is that the alternative has been modelled, repeatedly, and the models are sobering. A 2024 CSIS–MIT study, Confronting Armageddon, ran fifteen iterations of a war over Taiwan and found that the sharpest pressure for nuclear use arose precisely when one side faced a defeat it could not politically survive; in three iterations the game ended in nuclear catastrophe. China maintains a no-first-use policy, the authors noted, but judged that the commitment could fracture under extreme conditions — and that a further US nuclear buildup would do little to shore up deterrence (Source).
This is where the hawks’ confidence becomes a hazard. The comforting premise — that an adversary, struck hard enough, would absorb the blow and decline to escalate against the American homeland — is exactly the assumption these exercises puncture. Nuclear war is not a war of attrition settled by inventory. The difference between holding 5,000 warheads and 500 is, for practical purposes, no difference at all: destroying an opponent ten times over and destroying it once produce the same world. A modern state ceases to function once a few dozen warheads strike its major cities, and the United States is not exempt. Even a near-perfect first strike against China’s land-based force could not disarm what waits beneath the oceans. So long as that remainder survives, Washington and New York do not.
History offers an uncomfortable rhyme. Sixteenth-century Europe spent the better part of a century at war with itself, its Christians sorted into rival blocs prepared to kill over doctrine after Luther’s theses of 1517 hardened the quarrel with Rome (Source). The combatants were not divided by material interest so much as by belief, and the belief proved worth a continent’s blood. The present contest has its own orthodoxy — an establishment, entrenched in Western capitals, that treats containment of China as self-evidently prudent and open trade and shareholder value as naïve, and that reframes each failure as a case for more force (Source). It mistakes a wager for a strategy. The truth is that only the market can peacefully decide winners and losers.
That is the charge worth pressing. A policy that bets on the other side’s restraint while pursuing maximal confrontation is not foresight; it is gambling with a stake no one is authorised to risk. Deterrence has held for seventy years for one reason: each side believes the other will retaliate. The entire logic collapses the moment a planner persuades themselves it will not.
The whole purpose of Washington’s arsenal is to convince Beijing that a first strike means its own destruction — and the reverse holds with equal force. Even if the United States could destroy much of China’s land-based intercontinental force in a pre-emptive strike, it could not disarm China completely; so long as enough warheads survive beneath the oceans or deep in the Gobi, Washington and New York cease to exist alongside them. The delegation that flew home from Beijing appeared to have absorbed this, and to favour partnership over confrontation. The wager of the years ahead is whether it can hold the hawks in check.
