Just a few years ago, U.S. President Joe Biden caused a significant stir when he publicly confirmed that his administration would defend Taiwan if the island were attacked by China. This statement marked a notable divergence from the traditional U.S. policy of strategic ambiguity, under which Washington historically refrains from committing to any particular military action in advance. However, the diplomatic landscape shifted once again when U.S. President Donald Trump took a markedly different position in a television interview. Describing Taiwan as “a very good negotiating chip” in broader dealings with Beijing, Trump mused that the island was geographically close to China but far from the United States, thereby implying that American interests in Taiwan were negligible.
In making these remarks, Trump seemed to validate a fear long harbored by Asia watchers: that a U.S. president would be willing to loosen the United States’ historic commitment to Taiwan in order to cultivate a more favorable relationship with Chinese leader Xi Jinping.
Just days after those remarks, Secretary of State Marco Rubio told the Senate Foreign Relations Committee that there had been no official change in U.S. policy toward Taiwan. Nevertheless, Trump’s words remained deeply alarming, reflecting a broader realignment in Washington that extends far beyond the Oval Office. Since 2025, politicians from both major parties have increasingly shied away from affirming the United States’ long-standing support for the island. Meanwhile, Beijing is developing sophisticated new strategies to coerce Taiwan without resorting to open warfare, and Chinese leadership will be increasingly tempted to deploy these methods if they perceive that Washington’s commitment to Taipei is waning among both lawmakers and the general public.
Yet such an assessment would represent a grave miscalculation on China’s part. In reality, U.S. interests in Taiwan are growing rather than diminishing. Regardless of the fluctuating rhetoric emanating from Washington, the United States would ultimately be compelled to respond to any aggressive action by Beijing that threatens those vital interests, setting the stage for a perilous great-power crisis. To defuse this volatile situation, American leaders must urgently update their Taiwan strategy to reflect these new economic and geopolitical realities.
A GROWING DANGER
Taiwan’s unique international status has long rendered U.S. foreign policy in the region extraordinarily complex. The Republic of China, which is now commonly known as Taiwan, was a steadfast World War II ally of the United States. When the People’s Republic of China was established on the mainland in 1949, the Republic of China’s president, Chiang Kai-shek, relocated his government to Taiwan. For decades afterward, Washington maintained formal diplomatic ties exclusively with Chiang’s government rather than the mainland administration. As the Cold War intensified across the Pacific in 1954, the United States concluded a formal mutual defense treaty with Taiwan, designed in part to forestall increasingly aggressive artillery barrages from the mainland.
Nearly two decades later, however, President Richard Nixon and his national security adviser, Henry Kissinger, began engineering a historic diplomatic opening to the government in Beijing, fully recognizing that the shift would come at Taiwan’s expense.
Understanding that building formal diplomatic ties with Beijing would prove painful for Taipei and deeply controversial within the U.S. Congress—where Taiwan enjoyed robust bipartisan support—Nixon and Kissinger deliberately slow-walked the process. President Gerald Ford followed a similar cautious path before it ultimately fell to President Jimmy Carter to finalize the diplomatic transition. On January 1, 1979, the United States formally terminated its mutual defense treaty with Taiwan and recognized the mainland government as the sole legal government of China.
The reaction in Congress was swift and irate. Lawmakers from both parties rapidly drafted and passed the Taiwan Relations Act of 1979, legislation that remains in full force today. The law mandates that Washington provide Taipei with defensive arms, effectively creating the institutional trappings of a defense alliance despite the relationship’s unofficial status. In 1982, the Reagan administration supplemented these measures with the Six Assurances, which included explicit confirmations that Washington does not endorse Beijing’s sovereignty claims over Taiwan and promises that the United States would never use arms sales as a diplomatic bargaining chip.
For the fifty years that followed, U.S. policy toward Taiwan proved remarkably successful. Through sustained diplomatic partnership and regular arms sales, Washington helped underwrite peace and stability across the Taiwan Strait, allowing Taiwan to flourish as a vibrant democracy and economic powerhouse even as the United States maintained diplomatic and commercial relations with Beijing.
Lately, however, these commitments have come under intense strain. China has pursued a massive military modernization and buildup designed specifically to provide Beijing with the viable option of annexing Taiwan by force. Alongside its military preparations, Beijing has deployed coercive economic tactics, launched sophisticated cyberattacks, and interfered in local elections to apply persistent pressure on Taipei, while frequently conducting large-scale army and coast guard exercises to demonstrate its capacity to strangle the island. These developments have stoked widespread anxiety across the Pacific that the traditional U.S. partnership may no longer suffice to keep the peace in the Taiwan Strait.
Fears that China might attempt to forcibly retake Taiwan, potentially during Xi’s tenure, have escalated in recent years. Analysts have frequently pointed to 2027 as the beginning of a window of maximum danger, citing a 2021 statement by then-Commander of the U.S. Indo-Pacific Command Philip Davidson regarding when the People’s Liberation Army might achieve invasion readiness. Yet that timeline was never rigid or absolute, and Xi’s recent purge of more than 100 military officers has likely delayed the armed forces’ operational readiness. Current U.S. intelligence assessments do not anticipate an invasion in the immediate future, and most scholars agree that Beijing would view such a drastic move as a last resort, to be considered only if peaceful unification efforts completely fail.
Instead, the primary and immediate danger is that Xi will escalate a targeted pressure campaign designed to coerce Taiwan into negotiating a structural change in its political status. Since 2025, Chinese leaders have utilized direct diplomatic channels to the Trump administration—including a direct line between Xi and Trump—to insist upon American concessions regarding Taiwan in exchange for progress in broader bilateral trade talks. In May, Beijing successfully secured a temporary pause on a planned $14 billion U.S. arms sale and other vital defense funding packages earmarked for Taiwan. Chinese officials likely hope that further incremental concessions will permanently erode Taiwanese confidence in the reliability of the United States.
At the same time, China is actively preparing for more dramatic forms of coercion. Since 2022, the Chinese military has regularly practiced naval and aerial blockades of Taiwan, while its coast guard has simulated quarantines of the island’s major commercial ports. Beijing could also leverage customs enforcement or other administrative mechanisms to assert practical jurisdiction over Taiwan while attempting to minimize the likelihood of a direct U.S. military intervention.
Should Taiwanese President Lai Ching-te—who favors Taiwanese sovereignty but has avoided pursuing formal independence while in office—be reelected in 2028, and should Beijing conclude that the path to peaceful unification is permanently closing, Xi might consider deploying these coercive tools in late 2028 or early 2029, just as a U.S. presidential transition is underway. Given Trump’s history of alienating traditional allies in Asia and Europe, coupled with Washington’s limited practical means to counter a maritime quarantine at a moment’s notice, Beijing may calculate that it can execute a large-scale coercion campaign without facing severe international pushback.
THE INDISPENSABLE ISLAND
Taiwan’s rapidly growing strategic importance makes Beijing’s development of these new coercive options profoundly alarming. Washington no longer maintains its partnership with Taipei out of mere historical sentimentality, nor, as Beijing often alleges, simply to provoke China. Rather, the global artificial intelligence boom has firmly placed Taiwan at the very center of the modern world economy. Taiwan serves as an irreplaceable, critical supplier for the entire U.S. technology sector, and Washington increasingly recognizes that maintaining global leadership in artificial intelligence is impossible without uninterrupted access to Taiwanese industry.
The sheer scale of U.S. economic dependence on Taiwan is staggering. Taiwan currently stands as the fifth-largest trading partner of the United States. According to economic analyses by Bloomberg, a Chinese maritime blockade of the island would immediately imperil more than $250 billion in bilateral trade and could potentially shave over three percent off the U.S. gross domestic product within a single year. Furthermore, as much as 97 percent of the global supply of high-end logic microchips—essential components for smartphones, advanced computing, and critical infrastructure—are produced or packaged in Taiwan.
Losing access to these Taiwanese semiconductors could curtail global advanced electronics production by up to 60 percent, forcing manufacturing plants worldwide to rely rapidly on dwindling inventory reserves. Major American industrial sectors, including automotive and medical device manufacturing, could exhaust their chip inventories in a matter of weeks. Industry giants such as Amazon, Apple, and Nvidia rank among the primary customers of the Taiwan Semiconductor Manufacturing Company, collectively representing more than $14 trillion in market capitalization. With the ongoing artificial intelligence boom heavily buoying the U.S. stock market and the broader economy, a major crisis in Taiwan would trigger a catastrophic financial crash, potentially rivaling the market collapse seen at the onset of the COVID-19 pandemic.
The economic fallout of a Chinese campaign to squeeze Taiwan would extend far beyond American shores. The research firm Rhodium Group has conservatively estimated that a yearlong blockade of the island could cost the global economy between $2 trillion and $3 trillion. A full-scale military conflict would prove immeasurably worse; Bloomberg estimates indicate it could generate upward of $10 trillion in economic losses and plunge the global economy into a severe recession. Consequently, it is increasingly evident that the United States would be forced to respond if Taiwan’s vital supply chains were actively jeopardized. The economic and strategic cost of standing aside would simply be too high to bear.
COMMITMENT ISSUES
Yet, paradoxically, just as the United States needs to project unwavering resolve to prevent a crisis, Washington’s political support for Taiwan appears to be wobbling. Trump’s public musings regarding Taiwan’s geographical distance from the mainland United States and his willingness to treat arms sales as transactional bargaining chips represent the most prominent examples of this shift, but they are not isolated indicators. Certain foreign policy analysts have openly advocated that the United States alter its core posture to definitively oppose Taiwanese independence, or even contemplate withdrawing U.S. military forces from strategic bases in Japan and the Philippines that lie closest to Taiwan.
Public opinion within the United States is shifting in tandem. According to a survey published in July by the Chicago Council on Global Affairs, public sentiment toward China has warmed notably over the past two years. A 57 percent majority of Americans now express support for friendly cooperation and engagement with China, while only 40 percent favor active efforts to limit the expansion of Chinese power. Moreover, the proportion of Americans who view China’s territorial ambitions as a critical national security threat has dropped by more than ten percentage points since 2022, and those who favor deploying U.S. troops if China were to invade Taiwan has declined from 52 percent to just 38 percent.
To a significant degree, this softening of public support reflects a broader wariness among Americans toward international instability and protracted military conflicts. The pervasive public perception that the global order was descending into chaos helped fuel Trump’s successful 2024 presidential campaign, and as president, he has heightened that sense of unpredictability through assertive military actions in regions such as the Middle East and South America. American voters are currently feeling the domestic economic reverberations of prolonged conflict in the Middle East, which has further deepened widespread antiwar sentiment, as reflected in recent electoral outcomes. Political candidates who once rushed to burnish their credentials as foreign policy hawks on China now routinely hesitate to suggest that the U.S. military should directly defend Taiwan against an invasion, calculating that such hawkish rhetoric is out of step with the current political climate.
Of course, public attitudes can transform rapidly during an acute international crisis. Should China commit overt acts of military aggression against Taiwan, public support for a robust U.S. response could surge. If the early stages of a conflict involved American casualties or direct Chinese attacks on critical U.S. infrastructure, the domestic public could quickly rally around the flag and demand decisive military intervention.
At present, however, Beijing may operate under the dangerous assumption that the United States’ collective will and military capacity to fight are both severely diminished. The ongoing military commitments in the Middle East have substantially depleted U.S. military readiness for a potential contingency over Taiwan. The United States has exhausted large portions of its missile defense stockpiles, including approximately two-thirds of its Patriot interceptor inventory—which was already strained by military aid provisions to Ukraine—and as much as 80 percent of its Terminal High Altitude Area Defense interceptors used to counter regional drone and missile attacks. Even prior to these recent engagements, military analysts repeatedly warned that U.S. forces risked running out of long-range, precision-guided munitions during a protracted conflict in the Taiwan Strait; today, those munitions shortfalls have become acutely perilous.
Furthermore, these operational demands have drawn critical military assets away from the Indo-Pacific theater. In August, Washington relocated its final permanently stationed aircraft carrier in Asia, the USS George Washington, out of the region, while simultaneously shifting vital regional missile defense batteries to the Middle East.
THE NEW PLAYBOOK
The cumulative result of these trends is a sharply elevated risk of dangerous miscalculation. Should Chinese leaders assess that Washington’s commitment to Taiwan is faltering across both major political parties and that the nation is ill-prepared for a high-intensity fight, they might conclude they have a rare historic window to pressure Taiwan without triggering an American military response. Yet because the United States possesses a greater strategic and economic stake in Taiwan today than at any prior point in history, Beijing’s gamble could prove profoundly mistaken. China might enact a maritime quarantine or another aggressive coercive measure, only to find the United States intervening directly, thereby sparking an unprecedented great-power standoff.
Averting such a catastrophic showdown requires American leaders to decisively recommit to credible deterrence. First, Washington must overhaul how it communicates its strategic positions. Policymakers should clearly and consistently articulate in public remarks that the deep integration of the U.S. economy with Taiwanese technology exports makes peace and stability across the Taiwan Strait a vital, non-negotiable national interest. American political leaders must convey to Beijing that the United States holds an absolute obligation to prevent a crisis that would tank global financial markets, sever critical technological supply chains, and cripple numerous domestic industries.
Clarifying these vital national interests would not invalidate fifty years of careful diplomatic engagement with Beijing, nor would it necessitate any formal alteration of longstanding U.S. policy as codified by the Taiwan Relations Act, the Six Assurances, or the foundational joint communiques negotiated between 1972 and 1982. Rather, updated statements of intent would clearly signal to Chinese leadership that unilateral efforts to alter the cross-strait status quo by force or coercion remain wholly unacceptable to the United States, even if Taipei were pressured into temporary acquiescence. Washington could maintain its openness to a peaceful unification process, for instance, provided that any such process explicitly guaranteed the security and continuity of critical global supply chains.
Once Washington has articulated these vital interests with absolute clarity, it must back up its diplomatic posture with a comprehensive new playbook designed to deter Chinese actions that fall below the traditional military threshold. Given that Beijing may already be laying the groundwork for a maritime quarantine of the island, Washington cannot afford to tolerate incremental measures that disrupt lawful commerce and maritime traffic in and out of Taiwan. To deter such tactics, the incoming U.S. Congress should utilize legislation to register explicit, bipartisan opposition to Chinese blockades, quarantines, and administrative restrictions. Even if the executive branch were to adopt a more accommodating diplomatic stance, such congressional action would signal to Beijing that domestic political actors possess the means to force a firmer presidential response.
Furthermore, Congress should press the administration to prepare severe, punitive diplomatic and financial reprisals well in advance of any potential escalation. By pre-planning these economic penalties, Washington would demonstrate that any maritime pressure campaign would entail immediate, severe costs for Beijing while carrying unacceptable escalation risks.
Washington must simultaneously reinforce its military deterrence capabilities. The next Congress must pressure the executive branch to immediately release the stalled $14 billion package of arms sales destined for Taiwan, along with other delayed security assistance. Under the terms of the Taiwan Relations Act, Congress holds a legal obligation to ensure these transfers proceed. Pausing security assistance directly violates established U.S. policy, and allowing executive leadership to treat these defense packages as diplomatic concessions in a quixotic pursuit of rapprochement with Xi only serves to undermine America’s strategic hand.
Crucially, the United States does not need to—and should not—shoulder these responsibilities entirely alone. Key U.S. allies, including Germany, Japan, and South Korea, would suffer nearly as much as the United States if Beijing were to seize control of Taiwan’s semiconductor manufacturing base. These nations share a profound, mutual interest in quietly coordinating strategies to deter Chinese coercion while actively collaborating to diversify their microchip supply chains to make them structurally resilient. In the United States, this diplomatic groundwork does not need to wait for a presidential transition; members of Congress can utilize parliamentary delegations and international forums to begin developing joint contingency plans with foreign counterparts immediately.
As the 2028 U.S. presidential election approaches, candidates from across the political spectrum must speak candidly and clearly about the nation’s vital economic stakes in Taiwan and their steadfast commitment to effective deterrence. This does not require embracing bellicose or needlessly provocative rhetoric, but presidential contenders must state firmly that any attempt by Beijing to choke off critical global supply chains directly harms American interests and necessitates an assertive national response. Consistent, bipartisan messaging would signal unequivocally to Chinese leaders that they cannot rely on future administrations to honor prior policy concessions, while reassuring international allies that the United States remains a reliable and resolute partner in resisting economic aggression.
While the United States must continuously evaluate and update its Taiwan policy, ceding strategic ground—as recent rhetorical shifts have done—serves only to destabilize the cross-strait balance of power. Unlike many policies inherited from the Cold War era, the imperative of preventing aggressive coercion against Taiwan has grown steadily more vital with the passage of time. American interests in Taiwan are more transparent and easily understood today than ever before. Only by articulating those interests with absolute clarity and matching those words with resolute actions can the United States continue to avert a devastating crisis or conflict in the Pacific.
