Taiwan has completed another major round of military exercises as pressure from China around the island continues to shape one of the most dangerous security dilemmas in the Indo-Pacific. Taipei’s exercises have increasingly focused on decentralised command, protecting critical infrastructure, mobilising reserves and surviving the opening stages of a possible blockade or invasion rather than assuming Taiwan could defeat the People’s Liberation Army symmetrically. Beijing continues to insist that Taiwan is part of China and reserves the option of using force to achieve unification, while Taiwan’s government under Lai Ching-te argues that the island’s future cannot legitimately be determined without the consent of its people. The United States continues providing weapons and political support while maintaining deliberate ambiguity about the precise circumstances under which American forces would intervene. The military balance is important, but the underlying political problem is more fundamental: China’s claim rests heavily on territorial sovereignty and historical continuity, while Taiwan’s resistance increasingly rests on democratic self-determination. Both principles have legitimacy in international politics, but in Taiwan they point towards incompatible conclusions.
Beijing’s argument cannot be understood simply as expansionism. The People’s Republic of China considers Taiwan an unresolved consequence of the Chinese Civil War rather than an ordinary neighbouring country. From this perspective, permanent Taiwanese independence would represent the territorial fragmentation of China, made especially intolerable by foreign military support. Chinese nationalism therefore gives Taiwan significance far beyond its economic value. A Chinese government that formally abandoned the claim could face accusations that it had surrendered part of the nation. This is why purely economic arguments that war would be catastrophic may not be sufficient to guarantee peace. States sometimes value sovereignty and national identity precisely because they believe those goods should not be traded away for material prosperity.
Taiwan presents the opposite argument. Whatever Taiwan’s historical relationship with mainland China, its roughly 23 million inhabitants have spent decades developing institutions politically separate from Beijing and now live under a competitive democracy. The Chinese Communist Party does not govern Taiwan, Taiwanese citizens do not vote in Chinese elections and public opinion has developed a strong distinct Taiwanese identity. The philosophical question therefore becomes whether historical claims can override the contemporary political agency of the people actually living on the territory. If political legitimacy ultimately derives from consent of the governed, compelling Taiwan into political union against the preferences of its population becomes difficult to reconcile with self-determination.
Yet self-determination cannot operate without limits either. If every regional population possessing a distinct identity automatically acquired an unrestricted right to secession, states across the world could fragment continuously. International law therefore protects territorial integrity alongside self-determination, leaving deliberately unresolved where one principle should override the other. Taiwan sits in the most difficult part of that ambiguity because it already possesses most characteristics of a functioning state while lacking widespread formal diplomatic recognition. Its political reality is much clearer than its international legal status.
This ambiguity has helped preserve peace. Washington’s One China policy recognises the People’s Republic as China’s government while maintaining unofficial relations with Taiwan and opposing unilateral changes to the status quo. The United States has historically avoided specifying exactly whether it would fight China over Taiwan. Strategic ambiguity creates uncertainty for both sides: Beijing cannot assume intervention would not occur, while Taipei cannot assume American protection would make a declaration of formal independence costless. The policy therefore attempts to deter Chinese invasion and Taiwanese unilateralism simultaneously.
Ambiguity, however, becomes harder to sustain as China’s military capabilities grow. Deterrence depends on Beijing believing an invasion or blockade would fail or cost more than it could gain. If Chinese leaders eventually conclude that the military balance has shifted enough to make American intervention ineffective, uncertainty about Washington’s response becomes less valuable. Taiwan therefore needs greater ability to deny China a rapid victory, even if it could never match the PLA conventionally.
This explains the emphasis on drones, mobile missiles, mines, dispersed communications and reserve forces. Taiwan does not need a navy as large as China’s. It needs enough survivable capability that occupying the island becomes extremely difficult. This is sometimes described as a porcupine strategy: the objective is not dominating the stronger adversary but becoming too painful to consume. Ukraine has reinforced the logic by demonstrating how relatively inexpensive drones and distributed forces can impose enormous costs on a much larger military.
But Taiwan is not Ukraine. Geography makes the situation simultaneously easier and harder. The Taiwan Strait creates a substantial obstacle to invasion because amphibious warfare is extraordinarily complex. China would need to transport forces across roughly 130 kilometres of water while facing missiles, mines and potentially American or Japanese intervention. Yet Taiwan also lacks Ukraine’s land borders through which allies can deliver enormous quantities of weapons after war begins. A blockade could therefore become more dangerous than immediate invasion. Taiwan needs to stockpile before a crisis what Ukraine could continue receiving during one.
This makes economic resilience part of deterrence. Taiwan needs fuel, food, communications redundancy and enough infrastructure to survive prolonged disruption. The island’s semiconductor industry is central to the global economy, particularly TSMC’s production of advanced chips, but describing this as a “silicon shield” can be misleading. China may value semiconductor capacity while still prioritising sovereignty more highly. Furthermore, a war would probably damage the factories both sides hoped to control. Economic interdependence raises the cost of conflict; it does not automatically outweigh political objectives.
The United States faces its own credibility problem. Washington wants China to believe it might defend Taiwan without making a commitment so absolute that Taiwanese leaders can ignore escalation risks. Yet American credibility also affects allies including Japan, South Korea and the Philippines. If China changed Taiwan’s status through force and America remained passive, regional governments could question whether American security commitments elsewhere would remain credible. Taiwan therefore matters partly because alliance systems operate through expectations extending beyond the immediate territory.
This creates a danger familiar from Ukraine: credibility can become self-referential. America may feel compelled to act not only because Taiwan itself matters, but because failing to act could weaken future deterrence. China then interprets American involvement as evidence that Washington intends to contain China permanently. Each side’s attempt to preserve credibility strengthens the other’s perception of threat. Security dilemmas become most dangerous when defensive actions are structurally indistinguishable from preparations for offensive conflict.
India should observe this carefully because a Taiwan conflict would affect India even without direct military participation. Semiconductor shortages, disrupted Asian shipping and a global economic shock would affect Indian growth immediately. At the same time, a major US-China confrontation could alter the balance along the India-China border and across the Indian Ocean. India therefore has an interest in maintaining the status quo: opposing coercive changes while avoiding unnecessary movement towards formal positions that make peaceful compromise harder.
The strongest deterrence strategy is consequently one that combines military denial with political restraint. Taiwan should possess enough defensive capability that Beijing cannot expect rapid success. America and Japan should make intervention sufficiently plausible that China cannot calculate around them confidently. At the same time, Taipei should avoid symbolic steps towards formal independence that produce little additional practical sovereignty while dramatically increasing Beijing’s political cost of restraint. China, meanwhile, should recognise that coercion itself strengthens Taiwanese identity and makes voluntary unification progressively less plausible.
This may be Beijing’s greatest strategic contradiction. If China’s ultimate objective is political unification, repeated military intimidation can make the population it wants to unify increasingly hostile to that outcome. Power can compel behaviour more easily than belonging. A state can occupy territory through force; it cannot guarantee that the people living there will regard the resulting authority as legitimate.
Taiwan therefore represents more than another territorial dispute. It tests whether historical sovereignty or contemporary consent should carry greater weight when they conflict, whether economic interdependence can restrain nationalism and whether deterrence can remain stable as the military balance changes.
There may be no philosophically perfect answer to Taiwan’s status that China, Taiwan and the wider international community can all accept. That makes preserving an imperfect status quo more defensible than it sometimes appears. Ambiguity is frustrating because it postpones final justice, but when competing definitions of justice could produce a catastrophic war, postponement can itself become a form of political wisdom.
