In 2023 and 2024, the PLA Rocket Force underwent a sweeping personnel purge. Senior commanders were removed. The political commissar was replaced. Multiple defense industry executives associated with missile programs disappeared from public view. Western observers initially read the purge as evidence of catastrophic problems: missiles filled with water instead of fuel, silos with non-functioning lids, corruption rotting the strategic deterrent. Two years on, a more measured reading is possible.

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 Taiwan question is a civil war outcome that was never formalized. When Chiang Kai-shek’s Nationalist forces retreated to Taiwan in 1949 following their defeat by Mao’s Communist forces on the mainland, neither side accepted the result as permanent. The People’s Republic of China, proclaimed by Mao on October 1, 1949, claimed sovereignty over all Chinese territory including Taiwan. The Republic of China government, relocated to Taipei, continued to claim sovereignty over the mainland and to represent China in the United Nations until its expulsion in 1971. Both governments maintained, for decades, that there was one China and that they were its legitimate government. The dispute was not about whether Taiwan was Chinese. It was about which government was China’s.

In March 1996, the People’s Liberation Army conducted missile tests that bracketed Taiwan, splashing ballistic missiles into the sea north and south of the island in a demonstration designed to intimidate Taiwanese voters ahead of the island’s first direct presidential election. The Clinton administration responded by deploying two carrier battle groups to the region — the USS Independence and the USS Nimitz — in the largest American naval deployment in Asia since the Vietnam War. China backed down. The crisis ended without direct military confrontation. Its consequences have structured the strategic competition in the strait for the thirty years since.

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.

Australia’s relationship with the Taiwan question is defined by a gap between its strategic reality and its public political language. The strategic reality is that Australia is a treaty ally of the United States, a member of the Five Eyes intelligence partnership, a signatory to AUKUS with its consequent nuclear submarine commitment, and a country whose trade relationships, geographic position, and alliance obligations make it impossible to remain neutral in a Taiwan Strait conflict that involves American military action. The public political language has been more cautious, with Australian leaders consistently declining to state explicitly what they would do in a Taiwan contingency, preferring instead formulations about supporting the peaceful resolution of the dispute and avoiding statements that could be read as provocation by Beijing.

The People’s Republic of China has been conducting a sustained campaign of pressure against Taiwan that falls below the threshold of armed attack and above the threshold of normal competitive statecraft. This gray zone — the space between peace and war where coercion operates through ambiguity, exhaustion, and the deliberate exploitation of thresholds — has been the primary arena of Chinese pressure on Taiwan for years and is the operating environment that Taiwan’s defense establishment spends more of its daily attention managing than any invasion scenario.

China’s third aircraft carrier, the Fujian, underwent sea trials beginning in 2023 and has been advancing toward operational status. It is the first Chinese carrier equipped with electromagnetic aircraft launch system catapults — the same technology used on the American Gerald R. Ford class — which allows it to launch heavier aircraft with greater frequency than the ski-jump launch systems on China’s first two carriers, the Liaoning and the Shandong. The Fujian represents a genuine capability advance that brings Chinese carrier aviation meaningfully closer to the operational model that American carriers have perfected over decades. It does not bring the PLAN to American carrier aviation parity, and its operational utility in a Taiwan contingency is less straightforward than its physical characteristics suggest.

Ukraine’s experience since February 2022 has produced a global reassessment of what civil defense means in a modern conflict involving a large, technologically capable adversary striking civilian infrastructure. The Ukrainian example is relevant to Taiwan not because the two situations are identical — they are quite different in geography, military balance, and the specific threats each faces — but because Ukraine demonstrated that societal resilience, the willingness and capacity of a civilian population to sustain normal life and maintain government function under sustained attack, is a military asset of the first order. Taiwan’s civil defense posture, measured against the Ukrainian example, has been improving from a low base and remains inadequate for the scenario its military is preparing to fight.

The most important battle in a Taiwan conflict may be fought before the first missile is launched, on platforms that do not appear in military order-of-battle assessments, by actors who are never uniformed and never identifiable. China’s information operations against Taiwan are not a supplement to its military strategy. They are the precondition for making the military strategy work. A Taiwanese population that has been sufficiently demoralized, divided, and confused about what is actually happening and who can be trusted is a population that provides less political support for resistance, less capacity for civil defense mobilization, and less coherent pressure on allied governments to intervene.
