1. Key Takeaways

• The Singapore-US relationship is the most important strategic bilateral relationship in Singapore's foreign policy. It is not a formal alliance -- Singapore has never sought a mutual defence treaty -- but it functions as a deep security, economic, and intelligence partnership that has anchored American military presence in Southeast Asia since the end of the Cold War.

• The relationship was built on pragmatic convergence rather than sentiment. Singapore needed a great-power security guarantor after the British withdrawal East of Suez (announced 1967, completed 1971); the United States needed forward-deployed logistics and access points in Southeast Asia. Neither party has ever confused this convergence of interests with an identity of values.

• Lee Kuan Yew cultivated personal relationships with every US president from Lyndon B. Johnson to Barack Obama -- a span of nearly five decades. No other leader of a small state has enjoyed comparable access to the White House. Lee's value to successive American administrations lay not in Singapore's size but in his analytical clarity about Asian geopolitics, particularly regarding China.

• The 1990 Memorandum of Understanding (MOU) on US military access to Singapore's facilities -- later elevated to the Strategic Framework Agreement (SFA) in 2005 and renewed in 2019 -- is the structural foundation of the security relationship. Crucially, Singapore insists on the distinction between "access" and a "base": US forces use Singaporean facilities on a rotational basis but do not maintain a permanent garrison.

• The US-Singapore Free Trade Agreement (USSFTA), which entered into force on 1 January 2004, was Singapore's first bilateral FTA with a major economic power. It was as much a strategic signal as an economic arrangement -- demonstrating Singapore's alignment with the US-led economic order and its commitment to open markets.

• The Michael Fay caning incident of 1994 was the single most damaging episode in public perceptions of the bilateral relationship. The caning of an American teenager for vandalism generated a firestorm of American media outrage and Congressional criticism, but the Singapore government's refusal to capitulate -- while reducing the number of strokes from six to four as a gesture to President Clinton -- demonstrated its unwillingness to bend domestic law to foreign pressure, even from its most important partner.

• Defence procurement has been a major dimension of the relationship. Singapore has purchased F-5s, F-16C/D Fighting Falcons, AH-64D Apache helicopters, CH-47 Chinooks, and, most significantly, committed to purchasing F-35B Joint Strike Fighters -- the most advanced combat aircraft the US sells to any partner. The F-35 decision, announced in 2020 with deliveries expected from the mid-2020s, represents the highest level of US strategic trust in Singapore.

• The International Military Education and Training (IMET) programme has sent thousands of SAF officers to US military institutions since the 1960s, creating deep institutional ties between the two militaries. SAF units train regularly on US soil, including at facilities in Arizona, Idaho, and Louisiana, compensating for Singapore's lack of domestic training space.

• Changi Naval Base, which opened in 2004, was designed to accommodate US aircraft carriers. It is the only facility in Southeast Asia capable of berthing a Nimitz-class or Ford-class carrier, and its construction was explicitly intended to facilitate continued US naval presence in the region.

• Chan Heng Chee served as Singapore's Ambassador to Washington from 1996 to 2012 -- an extraordinary sixteen-year tenure that spanned four US presidencies (Clinton, Bush, Obama) and made her the most influential Singaporean diplomatic figure in the bilateral relationship after Lee Kuan Yew himself.

• The US has consistently been the largest or second-largest source of foreign direct investment (FDI) in Singapore. American companies have invested over US$300 billion cumulatively in Singapore, making it the single largest US FDI destination in Asia. This economic depth gives the relationship a commercial ballast that pure security ties would lack.

• The intensification of US-China strategic rivalry from the mid-2010s onward has placed Singapore in an increasingly uncomfortable position. Singapore has consistently refused to "choose sides," maintaining that it is not in its interest or in the region's interest to be forced into a binary alignment. This position has periodically frustrated both Washington and Beijing.

• The Trump-Kim summit, hosted in Singapore on 12 June 2018, demonstrated Singapore's unique positioning as a trusted venue for sensitive diplomacy -- acceptable to both the US and North Korea -- and its willingness to invest significant resources in facilitating great-power diplomacy.

2. The Record in Brief

The Singapore-US relationship is best understood in five phases: tentative Cold War alignment (1965-1975), deepening security ties (1975-1990), the post-Cold War strategic framework (1990-2005), mature partnership under stress (2005-2020), and navigating great-power rivalry (2020-2026).

In the first phase, newly independent Singapore confronted a Southeast Asia in turmoil. The Vietnam War dominated American strategic attention. Singapore under Lee Kuan Yew was broadly sympathetic to the US commitment in Vietnam -- not from enthusiasm for the war itself, which Lee privately doubted could be won on American terms, but because he understood that US military presence in the region provided the security umbrella under which Southeast Asian states could focus on nation-building and economic development. Singapore provided logistical support to US forces, including ship repair facilities at the former British naval dockyards at Sembawang, and R&R (rest and recreation) facilities for American servicemen. This was not a formal alliance but a practical arrangement that served both sides.

The second phase was triggered by two events: the fall of Saigon in April 1975, which raised questions about American commitment to Asia, and the British military withdrawal from Singapore, completed in 1971, which removed the only great-power military presence on the island. Singapore now faced a strategic vacuum. Lee Kuan Yew argued consistently -- in Washington, in regional forums, and in private -- that continued US engagement in Asia was essential. He was among the first Asian leaders to articulate the argument that US military presence was a public good for the region, providing stability that enabled economic growth. The 1980s saw steady deepening of the military relationship, culminating in the 1990 MOU on US military access.

The third phase, from 1990 to 2005, was transformative. The closure of US bases at Subic Bay and Clark Air Base in the Philippines in 1991-1992 -- after the Philippine Senate refused to renew the bases agreement -- created a strategic opportunity for Singapore. The 1990 MOU, signed by Prime Minister Goh Chok Tong and President George H.W. Bush, allowed US forces to use Singapore's air and naval facilities on a rotational basis. This was not a replacement for the Philippine bases -- Singapore's facilities were smaller and the arrangement was deliberately framed as "access" rather than "basing" -- but it provided the US with a crucial logistics hub in the Strait of Malacca and the South China Sea. The MOU was complemented by the USSFTA in 2004 and a growing web of military exercises, intelligence sharing, and counter-terrorism cooperation, especially after 11 September 2001.

The fourth phase, from 2005 to 2020, saw the relationship mature into a comprehensive strategic partnership. The Strategic Framework Agreement of 2005 elevated the MOU into a broader framework encompassing defence, economic, educational, and diplomatic cooperation. Singapore purchased increasingly sophisticated American military equipment. Changi Naval Base became the most important US naval logistics point in Southeast Asia. Intelligence cooperation -- never publicly detailed but understood to be extensive -- deepened further after the Jemaah Islamiyah threat was uncovered in 2001-2002. The relationship was tested by policy differences -- Singapore's caning laws, its media restrictions, occasional trade disputes -- but the strategic convergence held firm.

The fifth phase, from 2020 onward, has been shaped by the intensification of US-China rivalry, the COVID-19 pandemic, the return of great-power competition to Southeast Asia, and the question of whether Singapore can maintain its traditional balance. Under Prime Ministers Lee Hsien Loong and Lawrence Wong, Singapore has sought to deepen ties with both the US and China simultaneously, resisting pressure to align exclusively with either. The 2019 renewal of the Strategic Framework Agreement, the F-35 purchase decision, and continued expansion of bilateral military exercises signal that the US relationship remains foundational. But Singapore's leaders have been explicit that they will not join any coalition aimed at containing China, and that the region's interests are best served by an inclusive architecture in which both powers have a stake.

4. Background and Context

The Strategic Geography

Singapore's strategic significance to the United States derives from geography. The island sits at the southern tip of the Malay Peninsula, commanding the Strait of Malacca -- through which roughly one-quarter of global seaborne trade passes, including much of the oil and liquefied natural gas that fuels the economies of Northeast Asia. For any naval power seeking to project force or protect commerce in the Western Pacific, access to the Strait of Malacca and its approaches is indispensable. This geographical fact has shaped every phase of the bilateral relationship.

During the colonial era, Britain maintained a major naval base in Singapore precisely because of this strategic position. When the British withdrew, the question of who -- if anyone -- would fill the resulting security vacuum became the central strategic question for Singapore's leaders. Lee Kuan Yew never wanted Singapore to be undefended, and he never believed that Singapore alone could guarantee freedom of navigation through the strait. The logic pointed toward the only power with both the capability and the interest to maintain a naval presence in Southeast Asia: the United States.

The Cold War Frame

The early Singapore-US relationship was shaped by the Cold War, but Singapore's engagement with it was characteristically pragmatic. Lee Kuan Yew was anti-communist -- the struggle against the communist left within the PAP and the subsequent confrontation with the Barisan Sosialis had made that clear -- but he was not a Cold War ideologue. He assessed the Vietnam War, privately and with increasing candour, as a strategic error in execution if not in conception. He told American interlocutors that the US was right to signal commitment to the region but wrong in its methods, wrong in its choice of South Vietnamese partners, and wrong in believing that military force alone could defeat a politically motivated insurgency.

Singapore never joined SEATO (the Southeast Asia Treaty Organisation), which it regarded as a Western-imposed structure with limited regional legitimacy. Nor did Singapore align formally with the communist bloc. Its positioning was non-aligned in practice -- member of the Non-Aligned Movement from 1970 -- though pro-Western in strategic orientation. This distinction mattered: Singapore wanted American military presence in the region without the constraints of a formal alliance, which would have limited its diplomatic flexibility and alienated its neighbours.

The British Withdrawal and the American Question

The defining strategic shock of Singapore's first decade was the British announcement in January 1968 that all military forces would be withdrawn from East of Suez by 1971. The British military presence had been Singapore's security guarantee since the colonial era. It was also a major employer -- the bases accounted for roughly 20 per cent of Singapore's GDP and employed some 30,000 workers. The withdrawal forced Singapore to address two challenges simultaneously: building its own defence capability (the SAF and National Service) and finding a great-power partner to replace the stabilising role that Britain had played.

The answer was the United States, but the partnership took decades to formalise. In the late 1960s and early 1970s, the US was preoccupied with Vietnam and was, under the Nixon Doctrine, signalling reduced direct military commitment in Asia. Singapore could not expect, and did not want, the kind of large-scale military presence that the US maintained in Japan, South Korea, or the Philippines. What Singapore sought was a relationship that kept the US engaged in Southeast Asia -- present enough to deter aggression and maintain freedom of navigation, but not so dominant as to provoke Chinese or Soviet counter-moves or to make Singapore look like an American client state.

The Economic Foundation

The economic dimension of the relationship preceded and underpinned the security dimension. From the late 1960s, Singapore's economic development strategy -- designed by Goh Keng Swee and implemented through the Economic Development Board (EDB) -- actively courted American multinational corporations. Texas Instruments established semiconductor manufacturing in Singapore in 1968. Hewlett-Packard, General Electric, and scores of other American companies followed. By the 1970s, the US was Singapore's largest foreign investor, and American companies were among the biggest employers in the country.

This was not accidental. The EDB deliberately targeted US companies because they brought technology, management expertise, global market access, and -- crucially -- a strategic stake in Singapore's survival. A country in which billions of dollars of American capital was invested was a country that the US had reasons beyond geopolitics to protect. Lee Kuan Yew understood this calculus explicitly: economic integration with the US was itself a form of security.

By the 2020s, bilateral trade in goods and services exceeded US$100 billion annually. The US remained the largest or second-largest source of FDI in Singapore, with a cumulative stock exceeding US$300 billion. Over 5,500 American companies operated in Singapore, many using it as their regional headquarters for Asia-Pacific operations. The economic relationship had become so deeply embedded that it constituted an interest structure independent of any single political decision.

5. The Primary Record

Phase I: Tentative Alignment (1965-1975)

Lee Kuan Yew's first visit to Washington as Prime Minister came in 1967, when he met President Lyndon B. Johnson. The meeting was brief but significant. Lee urged continued US engagement in Southeast Asia and offered practical support -- not troops, which Singapore did not have, but facilities, intelligence, and diplomatic coordination. Johnson, consumed by Vietnam, was grateful for any Southeast Asian leader willing to publicly support the American presence. The relationship was transactional from the start, and both sides preferred it that way.

Singapore's support for the US in Vietnam was calibrated and limited. It did not send combat troops, unlike Australia, New Zealand, South Korea, Thailand, or the Philippines. It provided logistical support, including ship repair at the Sembawang dockyards (which Singapore took over from the departing British), and it hosted American servicemen on R&R. Lee's public statements supported the principle of US engagement while his private assessments grew increasingly pessimistic about the war's trajectory.

The Nixon Doctrine of 1969, which stated that the US would honour its treaty commitments but expected Asian nations to take primary responsibility for their own defence, was received in Singapore with mixed feelings. On one hand, it validated Singapore's approach of building the SAF rather than relying on foreign protection. On the other, it raised questions about the depth of American commitment. Lee's response was characteristic: he redoubled efforts to build the SAF while simultaneously working to ensure that the US did not disengage entirely from the region.

Phase II: Building the Security Relationship (1975-1990)

The fall of Saigon on 30 April 1975 was a watershed. Singapore's immediate fear was not a North Vietnamese invasion but the broader implications of American withdrawal: if the US could be defeated and humiliated in Vietnam, what confidence could small states have in American staying power? Lee Kuan Yew became one of the most articulate advocates for continued US engagement in Asia, arguing in speech after speech, op-ed after op-ed, and private meeting after private meeting that American withdrawal would create a vacuum that the Soviet Union and eventually China would fill.

The argument worked -- slowly. Through the late 1970s and 1980s, Singapore steadily expanded defence cooperation with the US. SAF officers began attending American military institutions in larger numbers through the IMET programme. Joint military exercises became more frequent and more complex. Singapore began purchasing American military equipment -- initially modest systems, but by the mid-1980s progressing to F-16 fighter aircraft, a decision that signalled both strategic alignment and operational interoperability with US forces.

Lee Kuan Yew's personal diplomacy was central to this phase. He met every US president from Johnson onward: Nixon (with whom he developed a strong intellectual rapport), Ford, Carter, Reagan (who shared Lee's anti-communist instincts if not his analytical subtlety), and George H.W. Bush (who, as a former CIA director and Ambassador to China, appreciated Lee's geopolitical insights). Lee was not a supplicant in these meetings; he was a valued interlocutor. American presidents and their national security teams sought Lee's assessment of China, of ASEAN, of the balance of power in Asia. No other small-state leader commanded this kind of access, and Lee used it systematically to advance Singapore's interests.

The 1988 MOU on US military access was the formal product of this decade of relationship-building. It allowed US aircraft and naval vessels to use Singapore's air and naval facilities on a rotational, case-by-case basis. The language was deliberately restrained -- "access," not "basing" -- to preserve Singapore's non-aligned posture and avoid provoking regional neighbours. But the practical effect was significant: the US now had a reliable logistics point in the heart of maritime Southeast Asia.

Phase III: The Post-Cold War Transformation (1990-2005)

The end of the Cold War and the closure of US bases in the Philippines transformed Singapore's strategic significance. When the Philippine Senate voted in September 1991 not to renew the bases agreement, the US lost its largest military facilities in Southeast Asia: Subic Bay Naval Base and Clark Air Base. The question of where to relocate these capabilities -- or whether to accept reduced presence in the region -- became urgent.

Singapore moved quickly. Prime Minister Goh Chok Tong, who had succeeded Lee Kuan Yew in November 1990, signed an updated MOU with President George H.W. Bush that expanded US access to Singapore's facilities. The US Navy's Commander, Logistics Group Western Pacific (COMLOG WESTPAC), relocated from Subic Bay to Singapore in 1992. While Singapore was careful to emphasise that this was a logistics coordination unit, not a base, the practical significance was considerable: Singapore had become the US Navy's primary logistics hub in Southeast Asia.

The Goh Chok Tong era (1990-2004) saw the bilateral relationship broaden beyond security. Goh, less geopolitically focused than Lee but more attuned to economic and institutional dimensions, pushed for the US-Singapore Free Trade Agreement. Negotiations, launched in 2000, were completed with remarkable speed, and the USSFTA was signed on 6 May 2003 by Goh and President George W. Bush. It entered into force on 1 January 2004.

The USSFTA was significant on multiple levels. It was Singapore's first bilateral FTA with a major economy and only the fifth FTA the US had negotiated at that point. It eliminated tariffs on 92 per cent of bilateral trade in goods immediately, with the remainder phased out over ten years. It included comprehensive provisions on services, intellectual property, investment, government procurement, and -- controversially -- labour and environmental standards. For Singapore, the FTA was as much a strategic signal as an economic instrument: it locked Singapore into the US-led economic architecture and demonstrated that small states could negotiate as equals with the world's largest economy.

Tommy Koh, the veteran diplomat who had led the UNCLOS negotiations, served as Singapore's chief negotiator for the USSFTA. His combination of legal expertise, personal relationships in Washington, and diplomatic skill was widely credited with the agreement's successful conclusion. The negotiation required delicate handling of sensitive issues including capital controls (which Singapore insisted on retaining the right to impose in a crisis), chewing gum (the ban on which had become a minor irritant in US-Singapore relations), and intellectual property protection.

The September 11 Watershed

The terrorist attacks of 11 September 2001 added a new dimension to the bilateral relationship. Singapore's discovery in December 2001 of a Jemaah Islamiyah (JI) cell planning to attack US, British, Israeli, and Australian diplomatic and military targets on Singapore soil transformed counter-terrorism cooperation. The Internal Security Department's (ISD) dismantling of the JI network, in close coordination with US intelligence agencies, demonstrated both the terrorist threat to Singapore and the operational depth of US-Singapore intelligence sharing.

Singapore contributed to the US-led response to 9/11 in multiple ways: it deployed a tank landing ship, RSS Endurance, and a C-130 transport aircraft to support coalition operations in the Persian Gulf; it hosted US military aircraft and vessels transiting to the war zone; and it deepened intelligence sharing on terrorist networks in Southeast Asia. The counter-terrorism dimension gave the bilateral relationship an urgency and operational intensity that the Cold War partnership had never quite achieved.

Phase IV: Mature Partnership (2005-2020)

The 2005 Strategic Framework Agreement represented the formal maturation of the relationship. Signed during Prime Minister Lee Hsien Loong's visit to Washington, the SFA elevated the 1990 MOU into a comprehensive framework encompassing defence and security cooperation, policy dialogue, counter-terrorism, counter-proliferation, joint military exercises, technology transfer, and educational exchanges. It was renewed and updated in 2019 during Lee Hsien Loong's visit to the White House.

The SFA's practical manifestations were extensive. Joint military exercises expanded in scope and complexity: Exercise Tiger Balm (bilateral army exercise, annually since 1981), Exercise Commando Sling (air force), Exercise CARAT (Cooperation Afloat Readiness and Training, naval), and participation in multilateral exercises like RIMPAC (Rim of the Pacific). Singapore's air force maintained training detachments at US bases, including Luke Air Force Base in Arizona (F-16 training), Mountain Home Air Force Base in Idaho, and various facilities for helicopter and transport aircraft training. The SAF's ability to train on US soil compensated for Singapore's acute lack of domestic training space -- an island of 733 square kilometres cannot accommodate the range and manoeuvre requirements of modern military training.

Changi Naval Base, which opened in 2004 on the eastern tip of Singapore, was designed with the US Navy specifically in mind. Its deepwater berths and supporting infrastructure could accommodate Nimitz-class aircraft carriers -- the largest warships in the world. The first carrier visit to Changi, by USS Kitty Hawk, took place in 2001 (before the base's formal opening). Subsequent visits by carriers including USS Nimitz, USS John C. Stennis, USS George Washington, USS Carl Vinson, USS Ronald Reagan, and USS Theodore Roosevelt demonstrated that Changi had become a regular port of call for the US Seventh Fleet. In 2012, the US began deploying Littoral Combat Ships (LCS) to Singapore on a rotational basis -- initially one, eventually up to four ships -- further embedding the US naval presence.

Defence procurement deepened the relationship's industrial and technological dimensions. Singapore's air force operated a fleet of F-16C/D Block 52 aircraft, among the most advanced variants sold to any US partner. Its army operated AH-64D Apache attack helicopters and CH-47SD Chinook heavy-lift helicopters. Its navy's frigates and corvettes incorporated American combat systems. Each procurement decision was both a military capability choice and a strategic alignment signal: Singapore was investing billions of dollars in American equipment, creating interoperability with US forces and long-term supply chain dependencies that bound the two militaries together.

The most significant procurement decision came in 2020, when Singapore announced its selection of the F-35B (short take-off and vertical landing variant) as its next-generation fighter aircraft, initially planning to acquire up to twelve aircraft with an option for more. The F-35 programme is the most sensitive military technology the US shares with any partner, and the decision to sell the B-variant to Singapore -- with its advanced stealth capabilities, sensor fusion, and data-sharing architecture -- represented the highest level of strategic trust. The US Congress approved the sale, and Singapore submitted its Letter of Request. Deliveries were expected to begin in the mid-2020s, with the aircraft eventually replacing Singapore's ageing F-16 fleet.

The Michael Fay Affair

No account of the Singapore-US relationship would be complete without the Michael Fay incident, which remains the most vivid episode in public memory of bilateral friction. In October 1993, Fay, an eighteen-year-old American living in Singapore, was arrested and charged with vandalism -- specifically, the spray-painting of cars. Under Singapore law, vandalism was punishable by caning, a judicial corporal punishment in which the offender is struck on the buttocks with a rattan cane.

Fay was convicted in March 1994 and sentenced to four months in jail, a fine of S$3,500, and six strokes of the cane. The sentence triggered a media and political storm in the United States. Editorials in the New York Times, Washington Post, and other major newspapers condemned the punishment as barbaric. Members of Congress introduced resolutions calling for clemency. President Bill Clinton personally appealed to the Singapore government, asking that the sentence be reconsidered.

The Singapore government stood firm on the conviction and the principle of caning but, in a calculated gesture, reduced the sentence from six strokes to four. The caning was carried out on 5 May 1994. Lee Kuan Yew, who was Senior Minister at the time, defended the sentence publicly, arguing that Singapore's low crime rate was a direct result of its tough criminal justice system and that yielding to foreign pressure would undermine the rule of law. He noted, pointedly, that many Americans -- including some who wrote to the Singapore embassy -- supported the caning, and that the US itself had far higher rates of vandalism and violent crime.

The Fay affair revealed the limits of the bilateral relationship. The US could not compel Singapore to change its domestic laws, and Singapore would not sacrifice its judicial sovereignty to accommodate American sensitivities. At the same time, the incident did not fundamentally damage the strategic relationship: security and economic cooperation continued without interruption. The episode became a case study in the management of values-based disagreements within a pragmatic partnership.

Chan Heng Chee: The Indispensable Ambassador

Chan Heng Chee's tenure as Singapore's Ambassador to the United States from 1996 to 2012 was the longest and most consequential ambassadorial posting in Singapore's diplomatic history. A political scientist by training -- she had been a professor at the National University of Singapore and had written an acclaimed study of Singapore's political system -- Chan brought intellectual depth, personal warmth, and strategic clarity to the role.

Chan arrived in Washington during the Clinton administration, navigated the transition to the Bush administration (and the post-9/11 transformation of US foreign policy), and served through most of Obama's first term. She was instrumental in the USSFTA negotiations, in managing the Michael Fay aftermath, in building Congressional relationships, and in explaining Singapore's governance model to an American audience that often viewed it with suspicion. Her tenure coincided with the most productive period in bilateral relations, and her personal relationships with senior figures across Washington's political spectrum -- Republicans and Democrats, executive branch and Congress, think tanks and media -- gave Singapore an influence in Washington that far exceeded its size.

Upon her return to Singapore in 2012, Chan was appointed Ambassador-at-Large and chairman of the Lee Kuan Yew Centre for Innovative Cities at the Singapore University of Technology and Design. Her successor as ambassador, Ashok Kumar Mirpuri, continued the tradition of long-serving, substantive ambassadors, serving from 2012 into the 2020s.

Phase V: Navigating Great-Power Rivalry (2020-2026)

The defining challenge of the current phase is the intensification of US-China strategic competition and the pressure it places on Singapore's traditional balancing strategy. Singapore's position, articulated consistently by Lee Hsien Loong, Vivian Balakrishnan (Minister for Foreign Affairs), and Lawrence Wong (who became Prime Minister in May 2024), is that Singapore will not choose sides, that the region is best served by an inclusive order in which both powers participate, and that US-China rivalry should not force smaller states into binary alignments.

This position has been tested repeatedly. The US has pressed Singapore and other Southeast Asian states to limit engagement with Chinese technology companies, particularly Huawei. Washington has pushed for greater alignment on Taiwan policy. American officials have occasionally expressed frustration with Singapore's unwillingness to frame its relationship with the US as explicitly directed against China. Singapore has pushed back consistently, arguing that its own security is best served by maintaining productive relationships with both powers and that the US should compete with China by offering the region a positive agenda -- trade agreements, investment, institutional engagement -- rather than by demanding that countries choose.

Vice President Kamala Harris's visit to Singapore in August 2021 was emblematic of the current dynamic. Harris used Singapore as a platform to reaffirm US commitment to Southeast Asia and to push back against Chinese assertiveness in the South China Sea. Singapore welcomed the visit and the signal of US engagement but was careful to frame the relationship in terms of shared interests rather than shared adversaries.

Singapore's imposition of sanctions on Russia following the invasion of Ukraine in February 2022 was a significant moment in the broader context of great-power relations. Singapore was the only Southeast Asian country to impose autonomous sanctions -- sanctions not mandated by the UN Security Council. The decision aligned Singapore with the US and the broader Western position but was framed not as alignment with any bloc but as a principled defence of sovereignty and territorial integrity: the principle that large states cannot simply invade and absorb smaller ones was existential for a city-state of Singapore's size.

The F-35 purchase, the continued rotational deployment of US Navy ships, the expansion of joint exercises, and the renewal of the Strategic Framework Agreement all signal that the security relationship with the US remains foundational. But Singapore has simultaneously deepened economic ties with China, maintained dialogue with Beijing on regional architecture, and refused to participate in arrangements that could be construed as anti-China coalitions. This dual-track approach -- deepen with both, align exclusively with neither -- is the essence of Singapore's current strategic posture.

6. Key Figures

Lee Kuan Yew (1923-2015): Founding Prime Minister and the architect of the US-Singapore relationship. His personal relationships with US presidents from Johnson to Obama gave Singapore access and influence far beyond its size. His assessments of Asian geopolitics, particularly China, were valued by successive US administrations. His 2013 book The Grand Master's Insights on China, the United States, and the World became essential reading in Washington foreign policy circles.

S. Rajaratnam (1915-2006): Singapore's first Foreign Minister (1965-1980). Established the foundational principles of Singapore's foreign policy, including the non-aligned but pro-Western orientation that enabled the US relationship. His intellectual framework -- small states need a rules-based order; great-power presence in the region is a stabilising force -- provided the strategic logic for the partnership.

Goh Chok Tong (b. 1941): Prime Minister 1990-2004. Signed the updated MOU on military access (1990), oversaw the expansion of US military use of Singapore facilities after the Philippine base closures, and pushed for the USSFTA. His more consensual style complemented Lee Kuan Yew's strategic vision.

Lee Hsien Loong (b. 1952): Prime Minister 2004-2024. Managed the relationship through the most sensitive period of US-China rivalry. Signed the Strategic Framework Agreement (2005), hosted the Trump-Kim summit (2018), authorised the F-35 purchase (2020), and articulated the "no choosing sides" position with increasing candour. His personal rapport with Obama was particularly strong.

Tommy Koh (b. 1937): Veteran diplomat and Singapore's chief negotiator for the USSFTA. Previously Ambassador to the United States (1984-1990) and Singapore's Permanent Representative to the UN. His legal expertise, personal networks, and negotiating skill were central to the FTA's successful conclusion.

Chan Heng Chee (b. 1942): Ambassador to the United States 1996-2012. The most consequential Singaporean diplomat in the bilateral relationship after Lee Kuan Yew. Her sixteen-year tenure built deep institutional and personal ties across Washington's political spectrum.

Bilahari Kausikan (b. 1954): Permanent Secretary of the Ministry of Foreign Affairs (2010-2013) and Ambassador-at-Large. The most intellectually formidable voice in Singapore's foreign policy establishment, he has articulated the complexities of navigating US-China rivalry with unusual candour, arguing that Singapore must resist pressure from both sides while maintaining strategic clarity about its interests.

K Shanmugam (b. 1959): Minister for Home Affairs and Minister for Law. Has defended Singapore's legal system and domestic governance model in international forums, including in the face of American criticism. His articulation of Singapore's position on the rule of law, judicial independence, and the right to maintain domestic legal systems different from Western norms has been central to managing values-based friction in the bilateral relationship.

Vivian Balakrishnan (b. 1961): Minister for Foreign Affairs from 2015. Has managed the bilateral relationship during the most intense period of US-China rivalry, emphasising Singapore's commitment to both relationships while articulating the limits of alignment. Hosted and facilitated the Trump-Kim summit in 2018.

Ashok Kumar Mirpuri (b. 1957): Ambassador to the United States from 2012, succeeding Chan Heng Chee. Has maintained continuity in Washington engagement during a period of significant political turbulence in the US, navigating the transition from Obama to Trump to Biden.

7. Stories and Anecdotes

Lee Kuan Yew and Nixon's bookshelf. Lee Kuan Yew developed a particularly strong intellectual relationship with Richard Nixon, whom he regarded as one of the most strategically sophisticated American presidents despite Watergate. After Nixon's resignation and retreat to private life, Lee continued to visit him. He recounted that Nixon's study was filled with books on foreign policy and history, and that their conversations -- freed from the constraints of office -- became even more candid. Lee's respect for Nixon's geopolitical mind, combined with his contempt for Nixon's domestic political failings, captured the duality of Singapore's relationship with America: admiration for the strategic architecture, exasperation with the domestic politics.

The Fay family's appeals. During the Michael Fay crisis, the Singapore embassy in Washington received thousands of letters -- the majority, officials later noted with some satisfaction, supporting the caning. Lee Kuan Yew himself cited a letter from a woman in the American South who wrote that she wished her own state would cane vandals. The episode became, for Singapore, a demonstration that American "values" were not monolithic and that many ordinary Americans respected Singapore's approach to law and order even when their government and media did not.

The chewing gum negotiation. During the USSFTA negotiations, the long-standing US complaint about Singapore's ban on chewing gum -- which had been imposed in 1992 after gum was found jamming the doors of MRT trains -- became a minor but persistent irritant. Tommy Koh and his US counterpart, Robert Zoellick, eventually settled on a compromise: Singapore would allow the import and sale of therapeutic and dental chewing gum (such as Nicorette) but would maintain the ban on recreational chewing gum. The compromise was characteristically Singaporean: pragmatic, face-saving, and somewhat amusing.

The Trump-Kim summit logistics. When Singapore agreed to host the Trump-Kim summit in June 2018, the government invested enormous effort in security, logistics, and protocol. The Capella Hotel on Sentosa Island was selected as the venue. The cost to Singapore was estimated at S$20 million -- which Vivian Balakrishnan described as "a small price to pay for peace." The summit produced a joint statement but no lasting agreement on denuclearisation. For Singapore, however, the event itself was the strategic payoff: it demonstrated that Singapore was the venue of choice for sensitive great-power diplomacy, trusted by all sides.

Chan Heng Chee and the Congressional breakfast. Chan Heng Chee made it a practice to host regular breakfasts and dinners for members of Congress, building relationships over years that gave Singapore unusual access to the legislative branch. In a city where most ambassadors focused on the executive branch, Chan's Congressional strategy gave Singapore early warning of legislative initiatives that might affect the bilateral relationship and, on several occasions, the ability to shape the debate before it hardened.

The Shangri-La Dialogue connection. The annual Shangri-La Dialogue, hosted by the International Institute for Strategic Studies (IISS) in Singapore since 2002, became the premier security forum in the Asia-Pacific and a critical venue for US-Singapore strategic interaction. US Secretaries of Defence have used the Dialogue as a platform for major policy speeches on Asia strategy, and the event's location in Singapore reinforces the country's role as a convening point for regional security discussions.

8. Arguments and Rhetoric

The "Access, Not Base" Distinction

Singapore has been meticulous in insisting that US military presence on its soil constitutes "access" to facilities rather than a "base." This distinction is not merely semantic. A base implies sovereignty concessions, permanent garrison, and -- in the Southeast Asian context -- neo-colonial dependence. Access implies host-nation control, rotational presence, and a relationship between equals. The distinction matters for Singapore's credibility with its ASEAN neighbours, particularly Indonesia and Malaysia, which are sensitive to foreign military presence in the region.

Bilahari Kausikan has articulated this with characteristic precision: Singapore provides the US with facilities because it is in Singapore's interest for the US to maintain a military presence in Southeast Asia. The moment it ceases to be in Singapore's interest, the access can be withdrawn. This is not an alliance obligation but a sovereign choice, renewed continuously because the strategic logic remains valid.

The "Not Choosing Sides" Doctrine

The most frequently articulated position in Singapore's current foreign policy discourse is the refusal to "choose sides" between the US and China. Lee Hsien Loong stated this most explicitly in his address to the Shangri-La Dialogue in 2019: "Singapore is a close friend and security partner of the US, and we are also a close friend and important economic partner of China. We do not want to be forced to choose between the two."

This position has been elaborated by successive ministers and officials. Vivian Balakrishnan has argued that the framing of US-China relations as a binary choice is itself a mistake -- that the relationship between the two powers is more complex than Cold War bipolarity, with deep economic interdependence coexisting alongside strategic competition. K Shanmugam has argued that ASEAN states should resist pressure to align with either power and should instead insist on an inclusive regional architecture.

Critics -- in both Washington and Beijing -- have questioned whether this position is sustainable. American commentators have argued that in a confrontation over Taiwan or the South China Sea, Singapore would have to choose. Chinese commentators have questioned whether a country that hosts US military rotations, buys F-35s, and shares intelligence with the CIA can credibly claim neutrality. Singapore's response has been that the question itself is wrongly framed: Singapore's interests are best served by preventing the confrontation that would force a choice, and its diplomatic energy should be directed at that prevention rather than at preparing for an alignment it does not seek.

LKY's "America as the Indispensable Power"

Lee Kuan Yew's public and private arguments for continued US engagement in Asia constituted perhaps the most sustained and influential advocacy by any foreign leader. His core thesis was simple: the US is the only power capable of maintaining a balance of power in Asia that prevents any single state from dominating the region. Without US presence, Asia would be dominated by China -- not necessarily through conquest, but through the gravitational pull of its size, economy, and civilisational weight. This outcome would be unacceptable to smaller Asian states, including Singapore, because it would reduce their autonomy and subordinate their interests to Beijing's preferences.

Lee made this argument to every US president he met, to Congressional delegations, to think tank audiences, and in his published writings. He was careful to distinguish this position from anti-China hostility: he was not arguing that the US should contain China, but that it should be present in the region as a counterweight that gave smaller states strategic options. The distinction was important because it allowed Singapore to maintain good relations with both powers simultaneously.

9. The Contested Record

The Depth of Intelligence Cooperation

The intelligence relationship between Singapore and the US is the most sensitive and least documented dimension of the partnership. It is publicly acknowledged in general terms -- the two countries share intelligence on terrorism, proliferation, and regional security -- but its operational depth is never discussed. Occasional disclosures, such as Edward Snowden's 2013 revelations about NSA surveillance that included Singapore-related intercepts, have hinted at a relationship far more extensive than official statements acknowledge.

The question of how deeply Singapore's intelligence services are integrated with US intelligence is contested. Some analysts argue that Singapore is effectively a member of the "Five Eyes" intelligence alliance in all but name, with access to US signals intelligence and a reciprocal sharing arrangement that goes well beyond what the public record reveals. Singapore's government has never confirmed or denied this, and the intelligence relationship remains the most opaque aspect of the bilateral partnership.

Was the USSFTA a Good Deal?

The economic merits of the USSFTA have been debated. Critics have argued that Singapore, as an already open economy with minimal tariffs, gave up more than it gained -- particularly in intellectual property protections and pharmaceutical patent rules that may have increased the cost of medicines. Defenders argue that the FTA's strategic value -- locking Singapore into the US economic orbit and signalling alignment -- was worth more than any purely economic calculation could capture.

The empirical record is mixed. Bilateral trade grew significantly after the FTA's implementation, but it is difficult to isolate the FTA's effect from broader trends in Asian economic growth and globalisation. The FTA's investment protections and dispute resolution mechanisms have been used by American companies operating in Singapore, suggesting real commercial value. The FTA also served as a template for subsequent US FTAs in the region, including the Trans-Pacific Partnership (TPP), which Singapore strongly supported and the US subsequently withdrew from under President Trump.

The "Semi-Alliance" Critique

Some scholars and commentators have described the US-Singapore relationship as a "semi-alliance" or a "virtual alliance" -- a relationship that functions like an alliance in practice without the formal treaty commitments. This characterisation has been resisted by Singapore, which argues that the absence of a formal alliance is not a deficiency but a deliberate choice. A formal alliance would constrain Singapore's diplomatic flexibility, oblige it to take sides in conflicts that do not concern it, and reduce its value as an interlocutor with China and other powers.

The critique nonetheless has some force. Singapore's military is more interoperable with US forces than with any other military. Its intelligence relationship with the US is deeper than with any other partner. Its defence procurement is overwhelmingly American. Its officers are trained predominantly in US institutions. In a genuine crisis in the South China Sea or the Taiwan Strait, the question of whether Singapore's relationship with the US is an "alliance" or merely a "partnership" might prove less important than the operational realities of interoperability, shared intelligence, and aligned strategic interests.

Human Rights and Values Friction

The bilateral relationship has been periodically troubled by American criticism of Singapore's domestic governance. The caning of Michael Fay was the most visible instance, but the US State Department's annual human rights reports have consistently noted concerns about restrictions on press freedom, the use of the Internal Security Act for preventive detention, limits on political opposition, and the death penalty for drug trafficking. Congressional figures have raised these issues, and American NGOs have been vocal critics.

Singapore's response has been consistent and unapologetic. Its leaders have argued that Singapore's governance model has produced outcomes -- safety, prosperity, social cohesion, low corruption -- that many countries, including the US, have failed to achieve; that different societies may legitimately organise themselves differently; and that American criticism often reflects a failure to understand Singapore's particular circumstances rather than a universal moral standard. K Shanmugam has been particularly forceful in defending Singapore's legal system, arguing in international forums that Singapore's rule of law is rigorous, independent, and effective, even if its outcomes differ from those an American court might produce.

10. Outcomes and Evidence

Security Outcomes

The security partnership has produced measurable outcomes:

• Military interoperability: The SAF can operate alongside US forces at a level matched by very few non-NATO partners. Joint exercises, shared doctrine, common equipment platforms, and decades of IMET training have created deep institutional familiarity.

• Deterrence: US military presence in Singapore, while rotational, contributes to deterrence against potential aggressors in the region. The ability to berth aircraft carriers at Changi Naval Base is a visible signal of US commitment.

• Counter-terrorism: The dismantling of the JI network in 2001-2002, achieved through US-Singapore intelligence cooperation, prevented planned attacks on multiple diplomatic and military targets in Singapore.

• Maritime security: The Strait of Malacca remains one of the most secure sea lanes in the world, a function partly of US naval presence facilitated by Singapore's access agreements.

Economic Outcomes

• Trade: Bilateral goods and services trade exceeded US$100 billion annually by the 2020s. The US is among Singapore's top three trading partners.

• Investment: US FDI stock in Singapore exceeded US$300 billion cumulatively, making Singapore the largest US FDI destination in the ASEAN region and one of the largest in Asia. Conversely, Singapore is a significant investor in the US, with GIC, Temasek, and private Singaporean companies holding substantial American assets.

• Employment: Over 5,500 American companies operate in Singapore, employing tens of thousands of Singaporean workers. Many use Singapore as their Asia-Pacific headquarters.

• Innovation: Bilateral cooperation in technology, research, and education has deepened, with Singapore's universities and research institutions maintaining extensive partnerships with American counterparts.

Diplomatic Outcomes

• Regional architecture: Singapore's relationship with the US has reinforced ASEAN centrality by ensuring that the US remains engaged with Southeast Asian institutions rather than bypassing them.

• Hosting role: Singapore's ability to host sensitive events like the Trump-Kim summit reflects the trust both sides of global disputes place in Singapore's neutrality and competence.

• Small-state influence: Singapore's strategic value to the US gives it diplomatic leverage that a city-state of 5.9 million people would not otherwise possess.

11. What the Archive Has Not Yet Revealed

Several dimensions of the Singapore-US relationship remain opaque or underexplored:

• The full scope of intelligence cooperation. The operational details of intelligence sharing -- what is shared, through what channels, under what conditions -- remain classified on both sides. The Snowden revelations offered glimpses but not a comprehensive picture.

• The internal deliberations on the F-35 decision. The process by which Singapore selected the F-35B over competing platforms (including European alternatives) has not been publicly documented. The strategic, technical, and political considerations that drove the decision -- including any conditions the US attached to the sale -- remain internal.

• Private communications between Lee Kuan Yew and US presidents. Lee's memoirs and published conversations reveal much, but the full record of his private exchanges with American leaders -- particularly his assessments of China conveyed in confidence -- will not be available until archives are opened, if they ever are.

• The economic cost-benefit of the USSFTA. A comprehensive, independent assessment of the FTA's net economic impact -- controlling for confounding variables -- has not been produced. The available studies are either government-sponsored or methodologically limited.

• Singapore's role in US operations in the Middle East. The extent of Singapore's logistical support for US operations in Iraq and Afghanistan beyond the publicly acknowledged contributions (RSS Endurance deployment, C-130 transport) has not been fully disclosed.

• The Trump administration's private pressure on Singapore. The Trump era introduced unpredictability into US foreign policy. Whether the Trump administration privately pressured Singapore on China-related issues, trade matters, or other bilateral concerns beyond what was publicly reported remains unclear.

• The full story of the Hendrickson affair. The 2017 arrest and prosecution of Dickson Yeo, a Singaporean PhD student at the National University of Singapore who was recruited by Chinese intelligence to spot and assess targets in the US policy community, touched on the Singapore-US intelligence relationship in ways that have not been fully explored.

12. Spiral Expansion Triggers / Spiral Index

This document connects to the broader Singapore Governance Knowledge Corpus at the following points, which may trigger expansion into dedicated documents or deeper exploration within existing ones:

• The Five Power Defence Arrangements (FPDA) -- SG-F-08. The FPDA (1971-present) is the other major security framework in which Singapore participates. The relationship between the FPDA (which includes the UK, Australia, New Zealand, and Malaysia) and the US bilateral partnership has not been systematically explored. Do they complement each other? Is there tension between them?

• The SAF and National Service -- SG-A-14. The SAF's force structure, doctrine, and equipment are shaped by the US relationship. The IMET programme, overseas training detachments, and procurement decisions are integral to understanding the SAF's development.

• ASEAN and Regional Architecture -- SG-F-07. The US-Singapore bilateral relationship exists within the multilateral framework of ASEAN-US relations. Singapore's role in shaping ASEAN's engagement with the US -- including the East Asia Summit, the ASEAN Regional Forum, and the US-ASEAN Strategic Partnership -- merits exploration.

• Singapore and China -- SG-F-03. The US-Singapore relationship cannot be understood apart from the Singapore-China relationship. The triangular dynamic -- how Singapore manages its two most important great-power relationships simultaneously -- is a central theme of contemporary Singapore foreign policy.

• The Foundations of Foreign Policy -- SG-F-01. The principles articulated in SG-F-01 -- sovereignty, non-alignment, rules-based order, balance of power -- provide the intellectual framework within which the US relationship operates.

• Economic Development Board -- SG-E-01. The EDB's role in attracting US investment was foundational to the economic dimension of the bilateral relationship. The story of how Singapore became the largest US FDI destination in ASEAN is partly an EDB story.

• Tommy Koh and UNCLOS -- SG-F-10. Tommy Koh's role in the USSFTA negotiations connects to his broader diplomatic career and his approach to international law and negotiation.

• The ISA and Internal Security -- SG-G-24. American criticism of the Internal Security Act and Singapore's response -- particularly the argument that security and liberty must be balanced differently in different contexts -- is a recurring theme in bilateral discourse.

• Lawrence Wong Transition -- SG-B-09. The transition to PM Lawrence Wong in 2024 and its implications for continuity in the US relationship merit tracking.

• The 2011 and subsequent elections -- SG-K-10. Domestic political changes in Singapore, including the rise of opposition voices on foreign policy, may over time create new pressures on the bilateral relationship.
