Deterrence is not a bilateral relationship. Every negotiation Washington conducts with an adversary under pressure is watched by every other adversary under pressure, and the conclusions drawn in those watching capitals shape decisions that have nothing to do with the original file. The framework emerging from the US-Iran nuclear talks is a nuclear agreement in name. In Beijing’s strategic calculus, it is a data point about American willingness to accept suboptimal outcomes when the cost of holding firm becomes politically visible.

The question has moved from speculative to urgent. With the Trump administration’s second term now producing a sustained record of signals, omissions, and transactional pivots, the Taiwan Strait is being scrutinized through the same lens that watched Ukraine’s western support erode — not in a single dramatic reversal, but in a slow dissolution of credibility.

The Ukraine comparison is structurally imperfect but politically instructive. Ukraine was abandoned not by a single decision but by a pattern: withheld aid, forced negotiations, bilateral summits that sidelined Kyiv. The mechanism was transactional pressure applied until a nominally sovereign partner had no viable alternative but to accept terms dictated by a larger power. Taiwan is watching that pattern and recognizing the template.

Beijing reports that China’s real GDP grew 5% in 2025. A significant body of independent economic analysis places the actual figure between 2% and 3%. The gap is not a rounding error. It is a structurally embedded credibility problem that distorts every downstream calculation about Chinese power—including the calculations made in Washington, Taipei, and Tokyo about what Beijing can sustain in a prolonged confrontation.

The Chinese government has long used GDP growth targets as political commitments rather than empirical forecasts. When the National Bureau of Statistics announces a figure that lands precisely on target, the precision itself is the tell. Economies do not perform to the nearest decimal point. The consistent gap between official figures and independent estimates—drawn from satellite data, electricity consumption, freight volumes, and cross-border trade flows—suggests systematic inflation of output numbers that serves the CCP’s domestic legitimacy requirements before it serves analytical accuracy.

The facts are straightforward. Taiwan President Lai Ching-te had sought $40 billion in supplementary defence spending to better deter China. After repeated delays by opposition parties, who hold the majority of seats, parliament approved only two-thirds of the money requested—all of it earmarked for US weapons, with domestically developed drones and missiles excluded from the package.

The war in the Strait of Hormuz is ending. The accounting for Taiwan has not yet begun.

Every resource consumed in the Gulf over the past weeks came from the same strategic account that underwrites deterrence in the Pacific. The aircraft carrier gap — no US carrier in the Pacific for more than two months — is not a logistical footnote. It is a signal. China read it. Taiwan felt it. The question now is what Beijing concludes about the durability of American commitments when a second crisis materializes in a different theater.

The argument that Taiwan’s semiconductor industry deters Chinese action runs on a tight loop. TSMC produces the world’s most advanced chips. Beijing depends on those chips. Therefore Beijing will not invade, because invasion destroys the supply. The argument is half right, and half right is dangerous because it sounds complete.

The first problem is that the silicon shield assumes Beijing values continuity of supply more than it values reunification. This assumption is unsupported. Xi Jinping has explicitly framed reunification as the unfinished business of the Communist Party’s national mission. Strategic patience has limits. A Taiwan that drifts further from Beijing year after year, hosting more US trainers and signing more defense contracts, eventually crosses a threshold where the political cost of inaction exceeds the economic cost of action. The shield holds only as long as the calculus does. Calculations change.

The United States has maintained a policy of strategic ambiguity toward Taiwan for more than four decades. It does not formally recognize Taiwan as an independent state. It does not provide a treaty guarantee equivalent to the commitments it has made to Japan, South Korea, or NATO allies. It does sell Taiwan defensive weapons under the Taiwan Relations Act, and it maintains unofficial relations through the American Institute in Taiwan. What it has not done is say explicitly and publicly whether it would use military force to defend Taiwan against a Chinese attack. This ambiguity has been the foundation of American cross-strait policy since 1979, and it has been under increasing strain as the military balance in the strait has shifted.

Taiwan’s defense establishment has been conducting an argument with itself for most of the past decade about what kind of military it needs. On one side: advocates of conventional deterrence, who want advanced fighter aircraft, large surface combatants, and the visible symbols of military capability that signal to Beijing that Taiwan can fight and to Washington that Taiwan is a serious defense partner. On the other side: advocates of asymmetric or “porcupine” defense, who argue that Taiwan cannot match PLA conventional capability in a symmetric competition and that investing in high-cost platforms that the PLA can destroy on the ground before they are ever used is strategically incoherent.
