In 2023, the CIA reported that Xi Jinping "has instructed the People's Liberation Army to be ready by 2027 to conduct a successful invasion of Taiwan." The Pentagon's 2025 annual report confirmed the timeline: China aims for basic military modernization and the ability to win regional wars by 2027, with full modernization by 2035. In December 2025, China deployed 89 warplanes, drone swarms, and blockade simulations in what Taiwan. Taiwan produces over 60% of the world's semiconductors and 92% of the most advanced chips at 7nm and below -- the ones powering AI.

1. Taiwan's Fall Would Be a Disaster (Elbridge Colby, Pentagon; Matt Pottinger, Former Deputy NSA)

Losing Taiwan doesn't just mean losing chips -- it means losing the Pacific.

It would be bad for the US. Elbridge Colby, confirmed as Under Secretary of Defense for Policy in April 2025, told the Senate that "Taiwan's fall will be a disaster for American interests." Taiwan's semiconductor industry is vital to US interests. He did qualify that Taiwan is "not an existential interest."

This is about more than a tiny island. Matt Pottinger, former Deputy National Security Advisor, warned that China could spark "a very serious crisis" over Taiwan within four years -- something that "should keep President Trump and many more people awake at night." He framed Taiwan as a linchpin: "From China's military doctrine, it's clear they view the subjugation of Taiwan as the first step in a regional and global hegemony strategy." Once China controls Taiwan, Pottinger argued, it can "flank Japan on its eastern side," projecting power beyond the first island chain.

Japan itself considers a Chinese invasion existential. Prime Minister Sanae Takaichi said on November 7, 2025 that any Chinese use of military force against Taiwan would be considered a "survival-threatening situation" for Japan. Japan is conducting its biggest military buildup in four decades, installing missile batteries and radar towers across the 160-island Ryukyu chain near Taiwan.

2. Not Worth Nuclear War (John Mearsheimer, U of Chicago; Michael Swaine, Quincy Institute)

A war over Taiwan could cost $10 trillion and end in nuclear exchange -- and the U.S. might not even win.

No nuclear bombs, period. John Mearsheimer, the University of Chicago political science professor and leading realist scholar, has argued that "Taiwan, at the end of the day, is not worth risking a potential nuclear conflict with China that would bring about mass suffering for the American people." He wrote that if forced to choose between war with China or withdrawing support for Taiwan, "it is in the United States' long term interest to opt for the latter."

Taiwan just isn't important enough. Michael Swaine, a Senior Research Fellow at the Quincy Institute, stated flatly: "Taiwan is not a sufficiently vital interest for the United States to go to war over." He advocates transitioning from strategic ambiguity to a new approach that enhances support for Taiwan but not war. While Foreign Affairs argued that the U.S. should discuss all this with China, openly -- and confirm we don't care enough to go to war.

The military math is uncertain at best. CSIS ran 24 wargames of a 2026 Chinese invasion: the U.S. and Taiwan won most scenarios, but at devastating cost -- "vulnerability of surface ships, massive coalition aircraft losses on the ground." And one set of plausible assumptions forecasts a Chinese victory. And China has the home-field advantage: Taiwan is 100 miles from the Chinese mainland but 5,000 miles from the U.S.

3. We're Already Independent, Thanks (President Lai Ching-te; Taiwanese Public Opinion)

Taiwan isn't waiting for America to decide its fate -- it's arming up and betting on being too important to abandon.

Independence is what the people want. A 2025 Taiwan Public Opinion Foundation survey found that 51.8% of Taiwanese adults prefer independence, 24.2% prefer maintaining the status quo, and just 13.3% want unification with China. President Lai Ching-te, a self-described "pragmatic worker for Taiwanese independence," has stated: "There is no need to declare independence because Taiwan is already a sovereign, independent country called the Republic of China."

Taiwan is putting money behind its position. In November 2025, Taiwan proposed a record $40 billion special defense budget, and Lai pledged to push defense spending above 3% of GDP. Taiwan procured additional High Mobility Artillery Rocket Systems from the United States in August 2025, bringing its total to 57 systems. Its 2025 National Defense Report outlines a strategy of "multilayered deterrence and resilient defense."

The silicon shield is a deliberate strategy, not a happy coincidence. International -- and in particular US -- reliance on TSMC's semiconductors is a separate and independent form of protection. In particular, Taiwan is pursuing supply chain security agreements with the U.S., Japan, India, and Australia. Taiwan's bet: make itself so economically indispensable that the cost of abandoning it exceeds the cost of defending it.

Where This Lands

The hawks have a point about consequences: if Taiwan falls, the first island chain breaks, the chip supply vanishes, and every U.S. ally in Asia recalculates whether American security commitments mean anything. The restrainers have a point about costs: $10 trillion, nuclear escalation risk, and wargame outcomes that depend entirely on which assumptions you plug in. On the other hand, Taiwan itself is neither waiting for rescue nor asking for a blank check -- it's arming up, spending more, and leaning into its semiconductor leverage. Where this lands depends on a question no wargame can answer: whether the U.S. is willing to fight a war it might not win to defend an island it can't afford to lose.
