China Fears a Real War Over Taiwan

The leak of the Pentagon’s classified “Overmatch Brief” has produced a familiar reaction. Headlines announce that China would defeat the United States in a war over Taiwan. Pundits conclude that American deterrence has failed. Some urge accommodation. Others demand vast new military spending. Both responses misunderstand what the assessment actually shows, and more importantly, what it does not. The central mistake is confusing the ability to impose costs with the ability to win a war. China may be able to seize Taiwan, an island roughly 100 miles from its coast. That does not mean China can win a war with the United States. Winning is not the same as landing troops, or even temporarily controlling territory. Winning means achieving political objectives at an acceptable cost. On that score, Beijing faces a dilemma it has not solved for 76 years.

Begin with a simple fact that often gets lost in technical discussions. Taiwan has remained free since 1949 not because it is unconquerable in principle, but because the United States deliberately set conditions that make conquest irrational. Deterrence is not a claim about impossibility. It is a claim about incentives. The US has never promised Taiwan an easy defense. It has promised something more durable, that any attempt to take the island by force would trigger consequences so severe that a rational Chinese leadership would decline to try. For more than seven decades, that judgment has been correct.

Critics will object that the military balance has changed. China has built missiles, ships, and aircraft at a staggering pace. Taiwan lies close to the mainland. The US must project power across the Pacific. These facts are real. They are also incomplete. An amphibious invasion of Taiwan would be among the most complex operations ever attempted. It would require air and naval supremacy across a contested strait, the rapid transport of hundreds of thousands of troops, continuous resupply under fire, and the immediate seizure of ports and airfields that Taiwan has spent decades hardening or preparing to destroy. Even D Day, often invoked as a historical analogy, occurred against a weaker opponent, with total air superiority, and with years of uncontested preparation. China would enjoy none of those advantages.

Geography compounds the problem. Taiwan is not an open plain waiting to be overrun. It is an island fortress with mountains running down its spine, dense urban centers, and a coastline that offers very few suitable landing beaches for large forces. Any invading army would be funneled into predictable corridors, exposed to mines, missiles, and artillery. Taiwan’s defenders know this terrain intimately. They have built their strategy around it. The so called porcupine approach is not designed to defeat China outright in a conventional sense. It is designed to slow, bleed, and entangle an invader long enough for the costs to become intolerable.

Suppose, however, that China manages to land significant forces. What then. The hard part would be only beginning. Urban warfare in cities like Taipei would be brutal and protracted. Seven million people live in the greater Taipei area. Modern cities favor defenders, not attackers. Every building becomes a fortress. Every street a choke point. Even a highly disciplined force would face staggering casualties. Occupation would not end resistance. It would begin it. Taiwan’s population is educated, technologically sophisticated, and politically cohesive. The will to resist is not an abstraction. Polling consistently shows that a majority of Taiwanese are prepared to defend their island. An occupying force would confront not only a military, but a society.

This is where the Overmatch Brief misleads when filtered through the media. Classified assessments often focus on narrow operational questions. How many missiles can be fired. How many ships might be lost. Which bases are vulnerable. These are important questions. They are not the same as the question statesmen must answer. Can China achieve its objectives without destroying its own regime. On that question, the answer is far less favorable to Beijing.

War with the United States would be economically catastrophic for China. The Taiwan Strait is one of the world’s most important shipping corridors. A conflict there would disrupt global trade on a scale not seen in modern history. China’s economy is deeply integrated into that system. It depends on exports, imported energy, and access to advanced technology. A war would invite sanctions, export controls, and financial isolation. Russia’s experience after Ukraine would look modest by comparison. China’s manufacturing base, its employment levels, and its long term development goals would all be placed at risk.

Nor would these costs be temporary. Even a nominal victory would leave China facing enduring hostility from the US and its allies. Japan, Australia, and others would not forget missile strikes on regional bases or shipping lanes. Supply chains would reroute permanently. Investment would flee. Growth would slow. The legitimacy of the Chinese Communist Party rests on a bargain with its people. Political control in exchange for rising living standards. A Taiwan war would shatter that bargain.

This is why the most serious threat to Xi Jinping is not military defeat alone. It is success at an unacceptable price. History is filled with leaders undone by wars they technically won. A bloody, grinding conflict that kills tens of thousands of Chinese soldiers, devastates the economy, and brings American strikes onto the mainland would test the regime’s stability in ways Beijing has not experienced since 1989. Internal unrest, elite fractures, and challenges to party rule are not speculative risks. They are predictable consequences of strategic overreach.

What, then, of the United States. Here clarity matters. America’s defense of Taiwan is not primarily about winning a war. It is about preventing one. Strategic ambiguity under the Taiwan Relations Act is often misunderstood as weakness. In fact, it is a calibrated instrument. By refusing to specify the precise conditions under which it would intervene, the US forces Beijing to assume the worst. China cannot be sure that an invasion would not trigger full American involvement. That uncertainty is a feature, not a flaw. It magnifies deterrence.

War games consistently show the same pattern. If the US stays out, Taiwan eventually falls. If the US intervenes, China’s invasion force is often destroyed before it can achieve its objectives, though at enormous cost to all sides. That is not a cheerful conclusion. It is a stabilizing one. It tells Beijing that the gamble is extreme, the odds uncertain, and the downside catastrophic. Deterrence works by shaping expectations, not by guaranteeing painless outcomes.

This also explains why claims of an imminent invasion should be treated with caution. Inside Washington, threat inflation is a persistent temptation. Military leaders seek budgets. Contractors seek contracts. Alarming scenarios loosen purse strings. This does not mean the threat is imaginary. It means it is often overstated. Surveys of independent security experts consistently show skepticism about near term war. China’s leadership is cautious. It studies history. It understands that wars of choice, especially against capable opponents, have a way of ending careers and regimes.

None of this implies complacency. Deterrence must be maintained. Taiwan must remain armed. The US must retain the capability to intervene. Allies must coordinate. But maintaining deterrence does not require accepting the premise that war is inevitable or that China holds a decisive advantage. The evidence suggests the opposite. Beijing has had decades to act. It has not done so. The reason is not lack of desire. It is fear of the consequences.

China can seize an island. It cannot easily subdue a people. It can inflict damage. It cannot control escalation once the United States is involved. Most importantly, it cannot win a war it is not willing to fight to the end. A true war with the US would not be a limited operation. It would be a systemic shock. China’s leadership knows this. That knowledge, more than any leaked briefing, explains why Taiwan remains free.

The proper response to the Overmatch Brief is not panic or surrender. It is sober analysis. Deterrence has worked for 76 years because it aligns with reality. War over Taiwan would be ruinous for all involved, but especially for the regime that starts it. As long as that remains true, and as long as the US continues to make it unmistakably clear, peace remains the most rational choice.
