Formosa Resolution of 1955
The Formosa Resolution of 1955 was a joint congressional resolution that authorized President Dwight D. Eisenhower to employ United States Armed Forces to protect Formosa (Taiwan), the Pescadores Islands, and related positions and territories from armed attack, particularly by Chinese Communist forces.[1] Signed into law as Public Law 4 on January 29, 1955, it provided the President with discretionary authority to take measures necessary for the area's defense, including responding to threats that could endanger Formosa's security, while requiring expiration upon determination that peace was reasonably assured, with notification to Congress.[1][2] Enacted amid the First Taiwan Strait Crisis, the resolution addressed escalating Chinese Communist bombardments and assaults on Republic of China-held offshore islands such as Quemoy, Matsu, and the Tachen Islands, which began in September 1954 and threatened to undermine U.S. strategic interests in the Western Pacific by potentially enabling People's Republic of China dominance over vital sea lanes.[3] President Eisenhower requested the measure to bolster U.S. commitments under the pending Mutual Defense Treaty with the Republic of China, allowing force deployment without prior congressional approval for immediate threats while clarifying that authority extended only to actions tied to Formosa's defense, not broader offensive operations.[4] The resolution passed the House of Representatives on January 25, 1955, by a vote of 410-3, with Senate approval following swiftly, reflecting broad bipartisan consensus on deterring Communist aggression during the Cold War.[5] Its significance lay in enabling U.S. military actions, such as the evacuation of Nationalist forces from the Tachen Islands in February 1955 and sustained deterrence against invasion, which contributed to de-escalation through subsequent Geneva negotiations and a temporary cessation of hostilities.[3] By affirming U.S. resolve to maintain friendly control over Formosa—deemed essential to Pacific stability—the resolution shaped long-term policy toward cross-strait tensions, serving as an early model for congressional authorizations of military force while underscoring the causal link between credible defense commitments and regional peace.[4][3]Historical Context
Origins in Chinese Civil War and Post-WWII Status of Taiwan
The Chinese Civil War, resuming in earnest after World War II from 1945 to 1949, culminated in the victory of the Chinese Communist Party (CCP) forces led by Mao Zedong over the Nationalist government of the Republic of China (ROC) under Chiang Kai-shek. By late 1949, the CCP had captured major mainland cities, including Beijing in January and Shanghai in May, forcing the ROC government and approximately 2 million troops and civilians to evacuate to Taiwan, where they established a de facto separate administration on December 7, 1949.[6][7] This retreat created a physical and political divide across the Taiwan Strait, with the ROC maintaining its claim as the legitimate government of all China while the CCP proclaimed the People's Republic of China (PRC) on the mainland on October 1, 1949.[6] Post-World War II arrangements regarding Taiwan's status originated in Allied wartime declarations. The Cairo Declaration of December 1, 1943, issued by the United States, United Kingdom, and Republic of China, stated that territories Japan had seized from China, including Formosa (Taiwan) and the Pescadores, "shall be restored to the Republic of China" after Japan's defeat.[8] The Potsdam Proclamation of July 26, 1945, reaffirmed these terms, prompting Japan to surrender Taiwan to ROC forces on October 25, 1945, under the Treaty of San Francisco framework, though the treaty itself did not explicitly assign sovereignty. However, the subsequent CCP victory nullified PRC control over Taiwan, preserving the island under ROC governance and rendering the declarations' implementation ambiguous in practice, as the ROC continued to assert its pre-1949 territorial claims without mainland authority.[8] United States policy toward Taiwan initially reflected a postwar retrenchment, with President Harry Truman announcing on January 5, 1950, that the U.S. defense perimeter in the Western Pacific excluded Formosa and would not involve military aid or bases there, prioritizing European commitments amid perceived low invasion risks.[9] This stance shifted dramatically following the North Korean invasion of South Korea on June 25, 1950, which Truman interpreted as evidence of broader Soviet-CCP expansionism; on June 27, he ordered the U.S. Seventh Fleet into the Taiwan Strait to neutralize it, preventing both PRC attacks on Taiwan and ROC incursions toward the mainland, thereby integrating Taiwan into U.S. anti-communist containment strategy.[10] By 1954, the PRC had amassed over 300 artillery pieces opposite the ROC-held offshore islands of Kinmen (Quemoy) and Matsu, initiating bombardment on September 3 that shelled ROC positions and signaled intent to compel unification, escalating tensions amid U.S. recognition of Taiwan's strategic value in blocking communist dominance in East Asia.[3]Escalation of the First Taiwan Strait Crisis
The People's Republic of China (PRC) initiated the First Taiwan Strait Crisis on September 3, 1954, with an artillery bombardment of Kinmen (also known as Quemoy), a Republic of China (ROC)-held island in the Taiwan Strait, followed by attacks on Matsu.[3][11] These actions, occurring after the 1953 Korean War armistice, represented expansionist probes by the PRC to test U.S. resolve in containing communist advances in the region, exploiting ROC vulnerabilities on forward positions while avoiding direct confrontation over Taiwan itself.[3] In response, the United States signed the Mutual Defense Treaty with the ROC on December 3, 1954, committing to joint defense against armed attack on Taiwan (Formosa) and the Penghu (Pescadores) Islands but explicitly excluding the offshore islands such as Kinmen and Matsu, which required separate congressional authorization for U.S. involvement.[12][13] This limitation stemmed from U.S. concerns over escalating to broader war, as the treaty's Article VI confined territorial application to Taiwan and Penghu without extending automatic protection to the more exposed outer islands.[13] Escalation intensified in January 1955 when PRC forces launched an amphibious assault on the Yijiangshan Islands, capturing them from ROC defenders between January 18 and 20 after heavy aerial and naval bombardment, resulting in the near-total destruction of ROC garrisons and significant PRC casualties.[14][15] U.S. intelligence assessments at the time judged that while PRC capabilities had grown, including amassed amphibious forces and airpower, they lacked the overall capacity for a successful invasion of Taiwan proper in 1955, though the offshore seizures heightened fears of a stepping-stone strategy toward the main island.[16][17] President Eisenhower sought legislative flexibility via the impending Formosa Resolution to deter further PRC aggression, citing intelligence on communist buildups as evidence of potential invasion threats that could draw in U.S. forces without prior congressional approval.[4][16]Legislative Enactment
Congressional Debates and Passage
President Dwight D. Eisenhower transmitted a special message to Congress on January 24, 1955, requesting joint resolution authority to employ U.S. armed forces in defense of Formosa (Taiwan), the Pescadores, and related positions against armed attack by Chinese Communist forces, explicitly without requiring a declaration of war.[4] The request emphasized the need for flexible presidential action to deter further communist aggression amid the ongoing Taiwan Strait Crisis, framing it as essential to preventing the fall of Formosa to forces that could threaten U.S. security interests in the Western Pacific.[18] Congressional debates centered on bolstering U.S. credibility in anti-communist alliances and halting the expansion of communist control in Asia, with Secretary of State John Foster Dulles testifying before committees that failure to act would undermine allied confidence in American commitments and invite broader Soviet-influenced domination.[19] Supporters, including bipartisan leaders, argued the resolution aligned with strategic necessity to counter isolationist tendencies, highlighting the islands' role in containing Chinese Communist offensives that had intensified since September 1954.[20] The House of Representatives approved H.J. Res. 159 on January 25, 1955, by a vote of 410–3, reflecting strong consensus across party lines.[18] Opposition remained minimal, with the three dissenting votes in the House and Senate primarily expressing concerns over the resolution's ambiguous scope regarding the defense of offshore islands like Quemoy and Matsu, which some feared could escalate to full-scale war without clear limits.[21] The Senate passed the measure on January 28, 1955, by 85–3, after brief committee deliberations that rejected amendments to restrict or expand territorial coverage.[18] Eisenhower signed the resolution into law as Public Law 84-4 on January 29, 1955, affirming congressional endorsement of executive flexibility in employing force for deterrence.[22]Provisions and Authorization Scope
The Formosa Resolution, enacted as Public Law 84-4 on January 29, 1955, authorized the President "to employ the Armed Forces of the United States as he deems necessary for the specific purpose of securing and protecting Formosa and the Pescadores against armed attack."[1] This grant explicitly extended to "the securing and protection of such related positions and territories of vital interest to the defense of Formosa and the Pescadores as are now in friendly hands," with the President tasked to determine which offshore islands or areas qualified under this criterion based on their defensive relevance.[1][2] The resolution's scope was strictly defensive, premised on responding to armed attacks by Chinese Communist forces that threatened U.S. security interests in the Western Pacific island chain, without extending to offensive operations or support for Republic of China (ROC) irredentist claims against the mainland.[2] It referenced the U.S.-ROC Mutual Defense Treaty of December 3, 1954—ratified by the Senate on February 9, 1955—affirming U.S. preparedness to join in "reasonable measures" to fulfill the treaty's objectives, but conditioned such participation on equality and appropriateness for assuring Formosa's defense.[1][2] Distinguished from a full congressional declaration of war under Article I, Section 8 of the Constitution, the resolution functioned as a targeted authorization for use of military force, granting the executive flexible discretion to address imminent threats without micromanaging operational details or requiring case-by-case approvals.[23] This mechanism balanced congressional intent to deter aggression—evident in the preamble's emphasis on the strategic menace posed by Communist attacks—with presidential authority to calibrate responses, including potential nuclear options if escalation warranted.[2] The authorization incorporated a conditional expiration upon the President's determination that "the peace and security of the area is reasonably assured by international conditions created by international organizations or other means," requiring notification to Congress.[1][2]Strategic and Military Implementation
U.S. Force Deployments and Nuclear Posturing
In response to the ongoing PRC bombardment of Republic of China-held offshore islands, the Formosa Resolution authorized President Eisenhower to deploy U.S. forces as necessary to secure Taiwan (Formosa), the Pescadores, and related positions such as Kinmen and Matsu.[2] This enabled the U.S. Seventh Fleet to conduct Operation King Kong from February 7 to 12, 1955, involving aircraft carriers, destroyers, and amphibious assault ships to evacuate approximately 35,000 ROC troops and civilians from the Tachen Islands chain, which faced imminent PRC seizure.[24] The operation, coordinated with ROC forces, underscored U.S. logistical support and naval reinforcement in the strait, deterring broader PRC advances by demonstrating resolve to protect allied holdings.[3] Complementing conventional deployments, Eisenhower pursued nuclear posturing to signal escalation risks. In early March 1955, he approved public statements by Secretary of State John Foster Dulles implying U.S. readiness to employ nuclear weapons against PRC staging areas in Fujian Province if attacks on Taiwan or offshore islands intensified, framing such use as proportionate to "limited war" scenarios.[25] Privately, Eisenhower viewed atomic capabilities as integral to deterrence, authorizing their integration into defense planning without explicit warhead deployments at the time, though tactical nuclear options were weighed against mainland targets.[26] These threats aligned with the administration's "massive retaliation" doctrine, aiming to impose unacceptable costs on PRC leadership amid Soviet hesitance to intervene.[27] Joint U.S.-ROC military planning intensified under the resolution's umbrella and the December 1954 Mutual Defense Treaty (effective March 3, 1955), focusing on offshore island defenses. The Joint Chiefs of Staff assessed enhancements to ROC troop dispositions on Kinmen and Matsu, recommending U.S. air and naval integration for resupply logistics—such as sustaining 80,000 ROC garrison troops via sea lifts—and contingency operations to repel amphibious assaults.[28] This included coordinated exercises for rapid U.S. reinforcement, prioritizing air superiority over the strait to counter PRC artillery and air incursions.[29] These deterrence mechanisms yielded empirical de-escalation: PRC forces halted major offensives by late April 1955, following Premier Zhou Enlai's Bandung Conference announcement of willingness to negotiate with the U.S., and shelling of Kinmen and Matsu ceased entirely on May 1, 1955.[11] The combined U.S. naval presence, nuclear signaling, and joint defensive preparations correlated with Beijing's tactical pause, averting invasion threats without direct combat engagement.[3]Role in Ending the 1954-1955 Crisis
The Formosa Resolution, enacted on January 29, 1955, provided explicit congressional authorization for President Eisenhower to employ U.S. armed forces in defense of Taiwan and associated offshore islands, signaling a credible U.S. commitment that correlated with the People's Republic of China's (PRC) restraint from further escalation.[2] Following its passage, U.S. naval operations, including the evacuation of ROC forces from the Dachen Islands in February 1955 under Seventh Fleet protection, demonstrated operational resolve without provoking a PRC invasion of Taiwan proper.[3] Large-scale PRC bombardments of Kinmen and Matsu, which had intensified in late 1954, diminished thereafter, with no attempted amphibious landings on Taiwan or the Pescadores.[11] This de-escalation aligned with diplomatic developments at the Bandung Conference in April 1955, where PRC Premier Zhou Enlai announced a willingness to negotiate with the United States, framing it as a response to perceived U.S. firmness rather than internal PRC moderation alone.[11] Shelling of the offshore islands effectively ceased by May 1, 1955, providing an off-ramp that avoided direct confrontation while preserving ROC control over Taiwan and the strategically vital Kinmen and Matsu enclaves.[30] The resolution's authorization thus contributed causally to this outcome by bolstering deterrence, as evidenced by the PRC's tactical withdrawal amid U.S. military posturing and aid commitments, rather than any unilateral PRC concession.[3] Post-resolution, ROC Taiwan experienced economic stabilization, facilitated by sustained U.S. assistance totaling approximately $527 million in economic aid and $948 million in military aid through the late 1950s, which supported infrastructure and defense without the disruptions of sustained conflict.[31] This period marked the absence of PRC incursions on Taiwan's main island, enabling the ROC to consolidate governance and initiate land reforms that laid groundwork for later growth, underscoring the resolution's role in maintaining a status quo against expansionist pressures.[3]Endurance Amid U.S. Policy Shifts
Challenges in the Nixon-Ford Era and Normalization with PRC
During the Nixon administration's pursuit of détente with the People's Republic of China (PRC), the 1955 Formosa Resolution faced scrutiny but retained its authority, preserving presidential flexibility in Taiwan Strait contingencies. The Shanghai Communiqué, issued on February 27, 1972, following President Richard Nixon's visit to Beijing, stated that the United States "acknowledges that all Chinese on either side of the Taiwan Strait maintain there is but one China and that Taiwan is a part of China," while expressing U.S. opposition to any unilateral change in Taiwan's status by force and interest in a peaceful settlement.[32] This formulation neither challenged the PRC's position nor abrogated existing U.S. defense commitments under the Formosa Resolution or the 1954 U.S.-Republic of China Mutual Defense Treaty, allowing continuity of strategic ambiguity amid shifting diplomacy.[32] Congressional efforts to repeal the resolution emerged in 1971, reflecting unease with executive-led rapprochement. The Senate Foreign Relations Committee reported S.J. Res. 48 on September 21, 1971, proposing to withdraw the president's authority to employ U.S. forces for defending Formosa (Taiwan) and the Pescadores.[33] During Senate debate on October 27, an amendment by Sen. Ted Stevens (R-Alaska) sought to delay repeal until April 15, 1972, but the measure ultimately failed to advance, ensuring the resolution's survival and maintaining U.S. leverage against potential PRC aggression despite diplomatic overtures.[33] The Ford administration (1974–1977) upheld Nixon-era policies, with President Gerald Ford reaffirming the Shanghai Communiqué's principles on August 12, 1974, while sustaining military presence on Taiwan.[34] Congress, however, enacted repeal of the Formosa Resolution on October 26, 1974, through section 502 of the Department of State Authorization Act (P.L. 93-475), amid broader reviews of U.S. security commitments initiated by Senate hearings in November 1969 and May 1970.[35] This legislative action did not immediately terminate defense obligations, as the 1954 treaty remained in force until its scheduled expiration on January 1, 1980, thereby preserving operational continuity and bargaining power through the transition to full normalization under President Jimmy Carter in 1979. The resolution's prior endurance thus sustained U.S. strategic options, countering pressures for unilateral concessions to the PRC.[34] Parallel congressional resistance to unchecked détente, exemplified by the Jackson-Vanik Amendment enacted over Ford's veto on January 3, 1975, linked most-favored-nation trade status to freedom of emigration in communist states, reinforcing an anti-communist posture that indirectly bolstered Taiwan's position by constraining executive accommodation with authoritarian regimes.Reagan Administration Reaffirmation and Taiwan Arms Sales
The Reagan administration countered apprehensions in Taiwan regarding potential U.S. abandonment following the 1979 normalization with the People's Republic of China (PRC) by reinforcing commitments to the island's security. On July 14, 1982, U.S. diplomat James Lilley conveyed the Six Assurances to Taiwanese President Chiang Ching-kuo, which explicitly rejected any U.S. mediation in cross-Strait talks, consultation with Beijing on arms sales to Taiwan, pressure on Taipei to enter negotiations, or support for a predetermined timeline for unification.[36] These pledges also affirmed no alterations to the existing framework of the Taiwan Relations Act and no preset endpoint for defensive arms provision, thereby sustaining the defensive authorization akin to the 1955 Formosa Resolution's empowerment of presidential action to secure Taiwan against armed attack.[37][38] Arms sales emerged as a flashpoint, with the administration approving transactions despite PRC diplomatic protests and threats of retaliation. In January 1982, Reagan authorized Taiwan to purchase additional F-5E fighter jets, forgoing more advanced F-16s but upholding the capacity for defensive operations, as part of a policy to maintain qualitative military parity.[39] By July, this extended to co-production of 30 F-5E and 30 F-5F variants under a four-year agreement valued at $622 million, framing such transfers as legally mandated defensive support rather than offensive escalation.[40][41] The August 17, 1982, U.S.-PRC joint communiqué acknowledged a gradual arms sales reduction contingent on reduced PRC threats, yet Reagan's internal guidance clarified that sales would persist absent peaceful cross-Strait resolution, prioritizing Taiwan's de facto security over Beijing's demands.[42] U.S. military footprint on Taiwan, diminished to advisory levels post-1979 withdrawal of combat forces, shifted emphasis to arms-enabled deterrence rather than basing.[43] This qualitative persistence, rooted in Formosa Resolution precedents, facilitated Taiwan's internal transformations: annual GDP growth averaged over 7% in the 1980s, propelling export-led industrialization, while security assurances underpinned the 1987 end to martial law and multiparty reforms under Chiang Ching-kuo and successor Lee Teng-hui.[44] Such stability under the U.S. umbrella empirically deterred PRC adventurism, enabling Taiwan's evolution into a high-tech economy and nascent democracy without direct territorial concessions.[45]Post-Cold War Adjustments and the Taiwan Relations Act
Following the dissolution of the Soviet Union in 1991, U.S. strategic priorities shifted away from Cold War-era containment, prompting adjustments in Taiwan policy that emphasized economic engagement with the People's Republic of China (PRC) while preserving deterrence against coercion. The Formosa Resolution endured as a statutory grant of presidential authority to employ U.S. armed forces for Taiwan's defense, complementing the Taiwan Relations Act (TRA) of April 10, 1979 (P.L. 96-8), which required the United States to provide Taiwan with defensive arms and maintain the capacity to resist any resort to force or coercion altering its security status. The TRA, enacted after the U.S. derecognition of the Republic of China on January 1, 1979, and termination of the 1954 Mutual Defense Treaty, established de facto relations through entities like the American Institute in Taiwan, ensuring continuity of military support without formal alliance obligations. This dual framework allowed flexibility in a unipolar environment, where overt commitments risked alienating Beijing but ambiguity deterred aggression. The 1995–1996 Taiwan Strait Crisis highlighted the integrated role of these instruments, as PRC missile tests and military exercises aimed at intimidating Taiwan prompted the U.S. deployment of two aircraft carrier battle groups—the USS Independence and USS Nimitz—to the region in March 1996, signaling resolve without direct combat. While not formally invoked, the resolution's broad authorization underpinned presidential discretion alongside TRA-mandated defensive posture, reinforcing strategic ambiguity that avoided explicit guarantees of intervention. This approach persisted amid post-Cold War PRC military modernization, with U.S. policymakers citing the resolution's non-expiration clause—tied to the President's determination of regional security—as justification for sustained readiness. Under President Bill Clinton, the "three noes" policy—announced on June 27, 1998, during a state visit to China—clarified U.S. non-support for Taiwan independence, a "one China, one Taiwan" stance, or Taiwan's entry into organizations requiring statehood, aligning with the 1972 Shanghai Communiqué while maintaining deterrence through undeclared defensive intent. Despite this verbal restraint, ambiguity endured, as evidenced by continued arms transfers and naval transits. The George W. Bush administration reaffirmed TRA implementation via arms sales notifications, including Patriot missile upgrades, treating Taiwan as a major non-North Atlantic Treaty Organization ally since 2003. President Barack Obama's tenure saw a $6.4 billion arms package notified to Congress on January 29, 2010, encompassing AH-64 Apache helicopters, Patriot PAC-3 missiles, and Black Hawk utility helicopters, directly fulfilling TRA Section 3(a) obligations amid PRC objections. Freedom of navigation operations in the Taiwan Strait, conducted routinely since the 1990s, challenged excessive maritime claims, indirectly bolstering Taiwan's de facto access to international waters. The Formosa Resolution has faced no repeal efforts post-Cold War, remaining cited in congressional deliberations on authorizations for use of military force, such as proposals for Taiwan-specific measures echoing its 1955 scope. This persistence reflects a policy adaptation prioritizing arms sustainment and operational deterrence over doctrinal overhaul, navigating PRC rise without eroding foundational U.S. leverage.Contemporary Relevance in the 21st Century
The Formosa Resolution, codified as Public Law 84-4, persists as active U.S. legislation, authorizing the president to deploy armed forces to secure Taiwan and related islands against armed attack, thereby offering a potential statutory mechanism for response without fresh congressional mandate.[46] This enduring legal foundation has fueled 21st-century proposals to adapt or supplement it, particularly as PRC capabilities have grown; for example, in 2020, experts advocated resurrecting an updated Authorization for Use of Military Force (AUMF) akin to the 1955 measure to explicitly empower presidential action in Taiwan contingencies, addressing perceived gaps in the post-1979 framework of strategic ambiguity.[47][48] Complementing this base, the Taiwan Enhanced Resilience Act of 2020—enacted within the National Defense Authorization Act for Fiscal Year 2021—directs U.S. assessments of Taiwan's military needs and promotes integrated deterrence, effectively extending the resolution's defensive rationale into contemporary resilience-building against PRC coercion. Under the Biden administration, invocations of the resolution's authority have surfaced in strategic clarity debates, with the president stating in May 2022 and September 2022 that U.S. forces would defend Taiwan against unprovoked invasion, signaling a potential operational reliance on the 1955 law amid eroding ambiguity.[49][47] PRC gray-zone operations, including a surge in air incursions—exceeding 1,700 flights into Taiwan's air defense identification zone in 2022 alone—have intensified post-events like House Speaker Nancy Pelosi's August 2022 visit, which prompted encirclement drills involving over 100 aircraft and 20 warships, probing U.S. commitments without full-scale war.[50][51] These tactics test the resolution's deterrence value, as its framework bolsters U.S. credibility with Indo-Pacific partners, where failure to uphold such precedents could undermine alliances like those with Japan and Australia by eroding perceptions of resolve against expansionist pressures.[52]Controversies and Debates
Arguments for Strong Commitment to Taiwan's Defense
Proponents of the Formosa Resolution argue that its authorization of U.S. military force in the Taiwan Strait reinforced containment of communism during the Cold War, preventing a potential domino effect across Asia by safeguarding Taiwan from People's Republic of China (PRC) invasion.[3] This commitment allowed Taiwan to pursue land reforms, export-led industrialization, and political liberalization, evolving into a democratic success story that contrasted sharply with mainland China's totalitarian system.[53] Under the protective umbrella signaled by the resolution, Taiwan's economy grew from a nominal GDP of approximately $1.7 billion in the mid-1950s to $756 billion in 2023, demonstrating how U.S. resolve enabled stable development that bolstered free-market alliances in the region.[54] The resolution's deterrence value is evidenced by the absence of a successful PRC invasion of Taiwan since 1955, despite Beijing's repeated military posturing and growing capabilities, including during the 1958 crisis where U.S. nuclear signaling and force deployments halted aggression.[55] Advocates, including Eisenhower administration officials, contended that clear congressional backing for presidential action projected unambiguous intent, discouraging PRC adventurism and maintaining cross-strait peace for decades.[56] Hawks like those aligned with Eisenhower warned that strategic ambiguity without such resolutions invites miscalculation and attack, as partial commitments fail to credibly signal defense of vital interests.[4] From a moral and ideological standpoint, supporters emphasized the imperative to resist totalitarian expansionism, aligning with Eisenhower's view that defending Taiwan preserved a "just and lasting peace" against communist threats to free peoples.[4] This stance not only upheld democratic values but also prevented the subsumption of Taiwan's 23 million people under PRC rule, which would have erased a key ideological counterexample in East Asia.[53] In contemporary terms, strong commitment remains vital due to Taiwan's dominance in semiconductor production, where TSMC manufactures over 90% of the world's most advanced chips essential for U.S. defense, computing, and economic competitiveness.[57] PRC control of Taiwan would grant Beijing leverage over global supply chains, potentially crippling U.S. technological superiority and raising costs for American firms reliant on Taiwanese imports for nearly half of advanced logic chips.[58] Thus, the resolution's legacy underscores arguments that unwavering defense commitments protect not just geopolitical stability but also critical economic stakes against authoritarian coercion.[59]
