Abstract

The United States–China contest is usually framed as a race for primacy. This paper argues that the more consequential threshold comes earlier: strategic incoercibility, the point at which an adversary can still impose severe costs but no longer retains a politically credible package capable of reversing choices a state regards as vital.

Three principal conclusions

  1. U.S. incoercibility on vital choices

    The United States is already strategically incoercible against China on vital national choices, whereas China has not yet clearly crossed that threshold.

  2. The 2027–2035 window

    On present trajectories, a maximum U.S.-allied package probably retains a route to Chinese reversal in 2027, reaches a genuinely uncertain threshold around 2030, and by 2035 would probably remain capable of extraordinary punishment without a credible route to reversal. The central trajectory is therefore toward mutual strategic incoercibility, not Chinese primacy.

  3. Trumpism and the decisive race

    Trumpism materially strengthens American incoercibility and slows China's approach to the threshold, but has not yet demonstrated that it can prevent it. The decisive race is between Washington's ability to renew and aggregate usable vetoes and Beijing's ability to remove them, build counter-vetoes and disrupt their aggregation.

Mutual incoercibility is not itself an Endgame. It would shift the contest from coercion toward systemic organization: whether either power can convert autonomy, centrality and capabilities into durable influence over the consequential choices of others.

Three possible endgames

  • American reconstitution
  • Chinese systemic breakthrough
  • Functionally distributed order

War is not a fourth endgame; it is one of the transition pathways that may lead there.

China does not need to surpass the United States in aggregate power to transform the strategic relationship. The earlier threshold is strategic incoercibility: the point at which an American-led coalition can still impose severe costs on China but can no longer plausibly compel Beijing to reverse a decision it regards as vital.

After incoercibility

Three endgames

Mutual incoercibility would settle the question of coercion. The larger contest would then turn on systemic organization. Three structural outcomes remain open.

01

American reconstitution

The United States renews technological and military advantage faster than China neutralizes it, reduces dangerous dependencies, shortens coalition latency and preserves enough legitimacy for network power to remain usable.

02

Chinese systemic breakthrough

China first reaches strategic incoercibility, then converts autonomy and industrial centrality into rules, liquidity, security, standards or institutions that durably organize third-state behavior.

03

Functionally distributed order

Neither power organizes the whole system. American finance and alliances, Chinese industrial centrality, European regulatory power and middle-power autonomy coexist by function. This resembles an interregnum more than a stabilized order.
