1. Key Takeaways

• Bilahari Kausikan (born 1954) is the most intellectually assertive and publicly visible foreign policy voice to emerge from Singapore's Ministry of Foreign Affairs in the post-Lee Kuan Yew era. His career spanned more than three decades of diplomatic service, culminating in his appointment as Second Permanent Secretary (2001-2010) and then Permanent Secretary of the MFA (2010-2013), before his transition to the role of Ambassador-at-Large and, more consequentially, to the role of Singapore's most prominent foreign policy public intellectual.

• Unlike most retired senior civil servants in Singapore, who observe a convention of discretion, Bilahari chose to become an active and often provocative commentator on international affairs, using Facebook posts, public lectures, op-eds, and two major books to articulate a vision of Singapore's foreign policy that is bracingly unsentimental, rooted in realpolitik, and unapologetic about the hard choices that small states must make to survive.

• His intellectual framework rests on what might be called "small state realism" — the proposition that Singapore's survival depends not on the goodwill of great powers but on a clear-eyed understanding of the international system's anarchic nature, the cultivation of strategic relevance to multiple powers simultaneously, and the refusal to indulge in moral posturing that a small state cannot back up with material power.

• Bilahari's most consequential public interventions have concerned the US-China strategic rivalry, where he has argued consistently that Singapore must not be forced to choose between the two powers, that ASEAN centrality is a useful fiction that should be maintained precisely because it is useful, and that China's influence operations in Southeast Asia are qualitatively different from those of other great powers because they seek to alter the psychological orientation of Chinese diaspora communities.

• His frank commentary on China — particularly his argument that Beijing employs a "divide and rule" strategy toward ASEAN and uses ethnic Chinese communities as instruments of influence — made him a controversial figure, admired by many for his candour and criticised by others (particularly in Beijing) for what they regarded as provocative anti-China sentiment.

• The public disagreement between Bilahari and Kishore Mahbubani in 2017-2020, often characterised as a debate between Singaporean realism and Singaporean idealism (or between pro-American and pro-Chinese orientations), became the most prominent intellectual confrontation in Singapore's foreign policy discourse and revealed genuine tensions within the establishment about how to navigate the changing global order.

• Bilahari's role during the Singapore-China tensions of 2016-2017 — the period encompassing the Terrex incident, the South China Sea arbitration fallout, and the Huang Jing case — was central, as his public articulation of Singapore's position was more explicit than official government statements, effectively creating a channel of strategic communication that operated in the space between official diplomacy and public discourse.

• His influence on younger generations of Singaporean diplomats and foreign policy thinkers has been substantial, not through institutional position but through the force of his arguments, the clarity of his writing, and his willingness to engage publicly with questions that most serving officials would consider too sensitive to address.

• Bilahari represents a distinctive type in Singapore's political ecosystem: the retired mandarin who becomes a public intellectual without becoming a political figure, operating with what appears to be tacit official tolerance if not endorsement, saying things that the government wants said but cannot say through official channels.

2. The Record in Brief

Bilahari Kausikan entered Singapore's Ministry of Foreign Affairs in 1981, joining an institution that had been shaped by the founding generation of S. Rajaratnam, Sinnathamby Rajaratnam, and the early diplomats who had to construct a foreign policy for a newly independent city-state that many doubted would survive. He rose through the ranks during a transformative period in Asian geopolitics: the final phase of the Cold War, the Asian financial crisis, the rise of China, and the reconfiguration of the US-led order in Asia.

His early diplomatic career included postings that gave him direct exposure to multilateral diplomacy and great-power politics. He served at Singapore's Permanent Mission to the United Nations in New York, where he gained experience in the multilateral system and developed the sharp debating skills that would become his hallmark. He also served as Singapore's Ambassador to Russia — a posting that gave him insight into the dynamics of great-power decline and the fragility of seemingly permanent political orders.

At the MFA, Bilahari was involved in many of the key episodes of Singapore's foreign policy from the 1990s onward. He played a role in Singapore's management of relations with Malaysia during periods of bilateral tension, in the formulation of Singapore's approach to ASEAN, and in the calibration of Singapore's position on the South China Sea disputes. His analytical mind and willingness to challenge conventional thinking made him influential within the ministry well before he reached its highest ranks.

His appointment as Permanent Secretary in 2010 came at a pivotal moment. The Obama administration was preparing its "pivot" or "rebalance" to Asia, China's assertiveness in the South China Sea was escalating following the 2009 nine-dash line submission, and ASEAN was struggling to maintain unity in the face of Chinese pressure. Bilahari managed the MFA during this period of heightened complexity, though it is difficult from the public record to separate his personal influence from that of the Foreign Minister, K. Shanmugam, or the broader cabinet.

His retirement from the Permanent Secretary position in 2013 did not mark a withdrawal from foreign policy. Instead, it inaugurated what has become the most productive and publicly visible phase of his career. Appointed Ambassador-at-Large — a title that gave him continued official standing without operational responsibilities — Bilahari began writing and speaking with a freedom that would have been impossible for a serving Permanent Secretary.

His Facebook page became, improbably, one of the most closely watched sources of foreign policy commentary in Singapore and arguably in Southeast Asia. In posts that ranged from a few lines to several thousand words, he offered analysis of developments in US-China relations, critiques of ASEAN's institutional weaknesses, assessments of specific leaders and their policies, and reflections on the enduring dilemmas of small-state diplomacy. These posts were read not only by Singapore's foreign policy community but by diplomats, journalists, and academics across the region.

His two books — Singapore Is Not An Island (2017) and Dealing with an Ambiguous World (2017) — collected and expanded upon his lectures and writings, providing a systematic statement of his worldview. The titles themselves are revealing: the first challenges the comfortable fiction that Singapore can somehow insulate itself from regional and global turbulence; the second acknowledges the fundamental uncertainty that characterises the international environment and argues that Singapore must learn to operate within ambiguity rather than seeking false certainties.

4. Background and Context

To understand Bilahari Kausikan, one must first understand the institutional culture of Singapore's Ministry of Foreign Affairs and why his post-retirement transformation into a public intellectual was so unusual.

The MFA is, by any standard, one of the most effective foreign ministries in the world relative to the size of the state it serves. Built from nothing after 1965, it developed a reputation for intellectual rigour, meticulous preparation, and a clear-eyed understanding of power dynamics that reflected the worldview of its political masters — first S. Rajaratnam, then Lee Kuan Yew himself. The ministry attracted some of Singapore's brightest minds, and the professional culture it developed was one of analytical precision tempered by pragmatism.

But it was also, characteristically for Singapore, an institution where public silence was the norm. Serving diplomats did not freelance on policy, did not publish personal opinions, and did not cultivate public profiles. The handful of exceptions — Tommy Koh's public lectures, Chan Heng Chee's academic publications — operated within understood boundaries and usually with explicit official blessing. The convention was that policy was made by ministers and communicated through official channels; civil servants, however senior, implemented and advised but did not publicly opine.

Bilahari broke this mould, not dramatically or suddenly, but gradually and with what appears to have been deliberate intent. The transition from Permanent Secretary to Ambassador-at-Large gave him a liminal status — still officially connected to the foreign policy establishment, but freed from the constraints of operational responsibility. He used this status to say things that were simultaneously personal commentary and, to many observers, a form of semi-official communication.

The context for his emergence as a public voice was the intensification of the US-China rivalry and its implications for Singapore and ASEAN. By the mid-2010s, Singapore's foreign policy establishment faced a challenge of a kind it had not confronted since the early years of independence: a fundamental restructuring of the regional order that threatened to compress Singapore's strategic space. The Obama administration's rebalance to Asia, China's island-building in the South China Sea, the 2016 arbitration ruling, and the election of Donald Trump as US president in November 2016 created a rapidly shifting landscape that demanded not just diplomatic management but public explanation.

Singapore's political leaders — Prime Minister Lee Hsien Loong, Foreign Minister Vivian Balakrishnan, and Defence Minister Ng Eng Hen — addressed these issues in official speeches and parliamentary statements. But there was a gap between what could be said officially and what needed to be understood publicly. Bilahari filled this gap. His commentary was sharper, more direct, and more analytically explicit than anything that could have come from a ministerial podium. When he wrote on Facebook that China's approach to the South China Sea was designed to "create a new normal" that would render the 2016 arbitration ruling moot, he was articulating what officials knew but could not say so bluntly. When he described ASEAN centrality as a "useful fiction," he was challenging a consensus that no serving diplomat could publicly question.

This raised an obvious question: was Bilahari freelancing, or was he an authorised channel? The answer is almost certainly somewhere in between. Singapore's system does not operate through explicit authorisation of this kind — there is no directive from the Prime Minister's Office saying "go forth and comment." But nor does it tolerate genuine freelancing by senior figures on matters of state. The most plausible interpretation is that Bilahari operated within a zone of tacit tolerance, saying things that were broadly aligned with the government's assessment but expressed with a directness that the government itself could maintain plausible distance from if necessary. This is a sophisticated form of strategic communication, and it is one of the reasons Bilahari's commentary attracted such attention: readers understood that his words, while personal, were not disconnected from the official mind.

5. The Primary Record

The Intellectual Framework: Small State Realism

Bilahari's worldview is rooted in a tradition that traces directly back to Lee Kuan Yew but has been refined and systematised through his own analytical lens. Its core propositions can be summarised as follows:

The international system is anarchic. There is no world government, no reliable enforcer of rules, and no guarantee that norms will be respected when they conflict with great-power interests. Small states that base their foreign policy on the assumption that international law or institutional frameworks will protect them are engaging in dangerous self-deception. Rules and institutions matter, but they matter because great powers find them useful, and they will be discarded or reinterpreted when great powers no longer find them useful.

Small states survive by being useful, not by being virtuous. Singapore's security ultimately rests not on its moral standing but on its strategic relevance to multiple powers. By positioning itself as a financial hub, a logistics node, a defence partner, and an interlocutor, Singapore makes itself useful enough to multiple actors that none has an interest in its destruction or subordination. This is not a comfortable position — it requires constant calibration and a willingness to manage relationships with powers whose interests may be mutually incompatible.

The greatest danger for a small state is irrelevance. If Singapore ceases to matter to the great powers — if it loses its economic dynamism, its strategic location ceases to be important, or its diplomatic capacity atrophies — it will lose the protective interest of the major players and become vulnerable to the depredations of its immediate neighbours and the indifference of the wider world. Bilahari has argued, somewhat provocatively, that there is no such thing as "diplomatic immunity through irrelevance" — the idea that a small state can protect itself by being too unimportant to bother with is a fantasy. In an interconnected world, even small states are affected by great-power competition, and passivity is not a strategy.

ASEAN is useful but limited. Bilahari has been more candid than most Singaporean officials in acknowledging ASEAN's limitations. He has described ASEAN centrality — the principle that ASEAN should be at the centre of the regional architecture — as a "useful fiction" that serves ASEAN's interests precisely because the alternative (a regional order dominated by a single great power) would be worse for all Southeast Asian states. But he has also argued that ASEAN's consensus-based decision-making makes it structurally incapable of acting decisively on issues where member states' interests diverge, particularly the South China Sea.

China's influence operations are qualitatively different. This is perhaps Bilahari's most controversial argument, and the one that has drawn the sharpest responses from Beijing. He has argued that all great powers attempt to influence smaller states, but that China's approach is distinctive in several ways. First, it seeks to exploit ethnic Chinese communities in Southeast Asia as instruments of influence, attempting to instil a sense of racial solidarity that transcends national identity. Second, it uses economic leverage — trade, investment, infrastructure loans — more systematically than other powers to create dependencies that constrain policy autonomy. Third, it employs a strategy of "divide and rule" toward ASEAN, cultivating bilateral relationships with individual member states that undermine collective cohesion. Fourth, and most fundamentally, China's influence operations aim to reshape the target's own perception of its interests — what Bilahari has memorably described as making you "do what China wants you to do while thinking you are acting of your own free will."

The US-China Rivalry

Bilahari has been one of the most cogent analysts of the US-China rivalry's implications for Southeast Asia. His core argument is that the rivalry is structural, not merely the product of particular leaders or policies, and that it will persist regardless of who occupies the White House or Zhongnanhai. He has rejected both the notion that engagement can return the relationship to its pre-2016 trajectory and the idea that confrontation or containment is feasible or desirable.

For Singapore, he has argued, the correct response is to refuse to be forced into a binary choice while simultaneously maintaining relationships with both powers that are substantive enough to preserve strategic space. This requires what he has called "dodging and hedging" — avoiding commitments that would lock Singapore into one camp while making itself valuable enough to both that neither is willing to force the issue.

He has been particularly critical of the idea, sometimes associated with Kishore Mahbubani, that Singapore should accommodate China's rise more willingly and avoid actions that Beijing perceives as provocative. Bilahari's counter-argument is that accommodation without reciprocity is not diplomacy but submission, and that a small state that adjusts its positions to avoid offending a great power has already surrendered the autonomy that is the foundation of its foreign policy.

The South China Sea and the Terrex Crisis

The period from mid-2016 to early 2017 was the most intense test of Singapore's China policy in decades, and Bilahari played a significant public role throughout. When the Permanent Court of Arbitration issued its ruling in Philippines v. China on 12 July 2016, Singapore's official position was carefully calibrated: it did not take sides on sovereignty claims but stated unequivocally that the ruling was binding under international law and must be respected. This was stronger than the positions of most ASEAN states and drew immediate Chinese displeasure.

At the September 2016 Non-Aligned Movement summit in Venezuela, Singapore resisted Chinese pressure to water down references to the arbitration ruling in the summit communique. Bilahari publicly commented on the episode, describing Chinese lobbying tactics in unusually direct terms. In November, the seizure of nine Terrex armoured vehicles in Hong Kong — during transit from military exercises in Taiwan — escalated the bilateral tension to crisis levels. The vehicles were held for more than two months before being released in January 2017, a period during which Chinese state media published pointed commentary about Singapore's need to "respect China's core interests."

Bilahari's public commentary during this period served several functions. It articulated Singapore's position more forcefully than official statements could. It signalled to domestic and international audiences that Singapore would not be intimidated. And it provided analytical context that helped frame the crisis not as a bilateral spat but as a test of the principles on which Singapore's entire foreign policy rested — the principle that a small state's autonomy depends on the consistent application of rules and norms, and that yielding to pressure on one issue creates a precedent that undermines the state's position on all issues.

The Mahbubani Debate

The public disagreement between Bilahari Kausikan and Kishore Mahbubani, which simmered from 2017 and erupted sharply in 2018-2020, was more than a personal quarrel between two prominent figures. It exposed a genuine fissure in Singapore's foreign policy thinking about how to navigate the US-China rivalry.

Mahbubani — a former Permanent Secretary of the MFA himself, later dean of the Lee Kuan Yew School of Public Policy, and a prolific author on the rise of Asia — had been arguing with increasing urgency that the West, and particularly the United States, was in decline, that Asia's rise was irreversible, and that Singapore and ASEAN needed to adjust their strategic orientation accordingly. His book Has the West Lost It? (2018) and subsequent writings suggested that Singapore's close security relationship with the United States and its insistence on rules that great powers were unwilling to follow risked unnecessarily antagonising China without providing commensurate benefits.

Bilahari's response was withering. In a widely circulated commentary, he accused Mahbubani of "intellectual dishonesty" and argued that his prescription amounted to advising Singapore to abandon the principles that had ensured its survival for more than five decades. The exchange was remarkable not only for its substance but for its tone — this was not a polite academic disagreement but a sharp confrontation between two former colleagues who represented genuinely different assessments of the international environment and Singapore's place in it.

The debate resonated because it mirrored a tension felt throughout Singapore's policy establishment and, to some extent, in ASEAN more broadly. Was the US-led order that had sustained Singapore's prosperity and security since independence going to endure? If not, what would replace it? Could Singapore maintain its current posture, or did it need to make a more fundamental adjustment? Bilahari's answer was that the order was indeed under strain but that Singapore's best response was to strengthen the principles and relationships that had served it well, not to pre-emptively capitulate to a new order whose shape was still uncertain.

7. Stories and Anecdotes

The Facebook diplomat. Bilahari's emergence as a social media commentator was itself improbable. A career diplomat trained in the tradition of private cables and confidential briefings chose Facebook — a platform associated with personal updates and casual commentary — as his primary medium for serious foreign policy analysis. His posts, often written late at night and running to thousands of words, became essential reading for Singapore's foreign policy community. Journalists and academics monitored his page for signals about Singapore's thinking. Foreign diplomats posted in Singapore were reportedly told by their capitals to follow his Facebook account. The incongruity of a former Permanent Secretary using a social media platform to conduct what amounted to parallel diplomatic communication was itself a commentary on the changing nature of public discourse.

"Useful idiot" and the Mahbubani exchange. The most dramatic moment in the Bilahari-Mahbubani debate came when Bilahari, in a public forum, characterised certain Singapore voices who argued for accommodation with China as being in danger of becoming "useful idiots" — a term from Cold War discourse describing people who unwittingly serve the interests of a hostile power. While he did not name Mahbubani directly in that specific exchange, the implication was unmistakable. The phrase reverberated through Singapore's intellectual circles, not least because it suggested that the policy stakes were not merely academic but existential.

The UN human rights battles. Earlier in his career, during the 1990s, Bilahari was part of the Singapore delegation that pushed back against what it saw as Western attempts to impose particular conceptions of human rights as universal norms. Singapore's position — articulated most prominently at the 1993 Vienna World Conference on Human Rights — was that human rights norms must be understood in their cultural and developmental context, and that the right to economic development and social stability was as fundamental as civil and political rights. Bilahari helped craft the rhetorical and analytical framework for this position, which was controversial but influential among developing countries. He later reflected that the "Asian values" debate had been crude in some of its formulations but that its core insight — that there is no single model of political development — remained valid.

Reading the Russians. Bilahari's posting as Ambassador to Russia gave him an experience that few Singaporean diplomats have had: direct observation of a great power in decline. He witnessed the turbulence of post-Soviet Russia, the rise of the oligarchs, and the early stages of Vladimir Putin's consolidation of power. This experience informed his later analysis of great-power dynamics, giving him a perspective that went beyond the US-China binary that dominates most discussions of Singapore's strategic environment. He has occasionally drawn on this experience in his commentary, noting that great-power decline can be as dangerous as great-power rise and that the international system's stability depends on the management of both.

The "small state, big voice" paradox. Bilahari has been acutely aware of the paradox inherent in his own public role: a representative of a tiny state speaking with a bluntness and confidence that exceeds what much larger countries are willing to express. He has addressed this directly, arguing that Singapore's very smallness gives it a certain freedom — precisely because it is too small to threaten anyone, it can say things that larger states cannot without being perceived as making a power play. This is the inversion of his "no diplomatic immunity through irrelevance" argument: while irrelevance offers no protection, smallness combined with relevance can confer a kind of moral authority, provided the small state has the substance to back up its words.

8. Arguments and Rhetoric

Bilahari's rhetorical style is distinctive among Singapore's foreign policy voices. Where Tommy Koh is avuncular and institution-building, where Chan Heng Chee is measured and academic, where Kishore Mahbubani is provocative but optimistic, Bilahari is analytical, combative, and deliberately unsentimental.

Several recurring rhetorical strategies characterise his work:

The refusal of euphemism. Bilahari names things directly. Where others might describe Chinese pressure on ASEAN states as "diplomatic activity" or "engagement," he calls it "coercion." Where others describe ASEAN consensus-building as "the ASEAN Way," he describes it as an institutional weakness that great powers exploit. This directness is itself a form of argument: by stripping away diplomatic language, he reveals the power dynamics that polite formulations obscure.

Historical analogy without determinism. He draws frequently on historical examples — the Congress of Vienna, the Concert of Europe, the Cold War, the fall of the Soviet Union — to illuminate contemporary dynamics, but resists the temptation to argue that history is repeating itself. His use of history is diagnostic rather than predictive: it reveals patterns and possibilities without prescribing outcomes.

The distinction between desirable and probable. A hallmark of Bilahari's analysis is the insistence on separating what we might want to happen from what is likely to happen. He has been critical of what he calls "aspirational thinking" in foreign policy — the tendency to confuse policy preferences with analytical assessments. When he argues that the US-China rivalry will persist, he is not celebrating this fact but insisting that policy must be based on probability, not hope.

Strategic empathy without sympathy. Bilahari is notable for his ability to articulate the perspectives of actors — including China, Russia, and the United States — whose policies he may disagree with. He has argued that understanding why China behaves as it does is not the same as approving of that behaviour, and that effective diplomacy requires the capacity to see the world through others' eyes without losing one's own perspective.

The sovereignty argument. Running through Bilahari's work is a robust defence of state sovereignty as the foundation of international order. He has pushed back against what he sees as Western attempts to erode sovereignty through doctrines like the "Responsibility to Protect" (R2P), arguing that these doctrines, however well-intentioned, can be weaponised by great powers to justify interventions that serve their own interests. At the same time, he has argued that sovereignty carries responsibilities — a state that cannot govern effectively or provide for its people will find its sovereignty eroded in practice even if it is respected in theory.

---

9. The Contested Record

Several aspects of Bilahari's role and arguments are contested or debated:

Authorised or freelance? The question of whether Bilahari's public commentary represents the views of the Singapore government or merely his personal opinions has never been definitively settled. His former colleagues at the MFA have maintained a studied silence on this question, neither endorsing nor disowning his remarks. This ambiguity is almost certainly deliberate — it allows the government to benefit from his commentary (which sets out positions that are broadly consistent with official policy) while maintaining the option to distance itself if any particular statement proves diplomatically costly. Critics argue that this arrangement is disingenuous; defenders argue that it is a sophisticated form of strategic communication appropriate to a small state operating in a complex environment.

Too hawkish on China? Bilahari's most persistent critics, particularly in Chinese academic and media circles, have accused him of being excessively hostile to China and of mischaracterising Chinese foreign policy as inherently aggressive or manipulative. Some Singapore-based analysts have also questioned whether his framings — particularly the "influence operations" argument — risk becoming self-fulfilling prophecies that poison the bilateral relationship. Bilahari's defenders respond that his analysis has been consistently vindicated by events, pointing to the Terrex seizure, the Huang Jing case, and various instances of Chinese diplomatic pressure as evidence that his warnings were warranted.

The Mahbubani debate: substance or personality? Critics of the Bilahari-Mahbubani exchange have argued that what was presented as an intellectual debate was partly a personal rivalry between two strong-willed former senior officials with different institutional bases and public profiles. Both men have denied this, but the personal edge to their exchanges — the "useful idiot" characterisation, Mahbubani's retort that Bilahari was confusing toughness with wisdom — suggests that the disagreement was not purely analytical.

The limits of realism. Some younger Singaporean foreign policy thinkers have questioned whether Bilahari's realism, however analytically powerful, is adequate to the challenges of the twenty-first century. Issues like climate change, pandemic preparedness, digital governance, and supply chain resilience require forms of international cooperation that pure realpolitik may not be equipped to deliver. Bilahari has acknowledged these challenges in his more recent writings but has argued that cooperation on functional issues does not require abandoning a realistic assessment of power dynamics — indeed, he has argued that effective cooperation is only possible between states that understand each other's interests clearly and do not harbour illusions about shared values that do not exist.

Human rights and the "Asian values" legacy. Bilahari's involvement in the human rights debates of the 1990s remains controversial. Western human rights scholars and organisations have criticised Singapore's position — and Bilahari's articulation of it — as providing intellectual cover for authoritarian governance. Bilahari has responded that the critique confuses the defence of cultural pluralism with the defence of authoritarianism, and that the Western model of human rights is itself a culturally specific product that reflects particular historical experiences and political traditions.

The voice of the establishment or an independent mind? Related to the "authorised or freelance" question is the deeper question of whether Bilahari's thinking represents genuine intellectual independence or a sophisticated articulation of establishment views. His admirers argue that his willingness to challenge consensus positions — on ASEAN centrality, on the sustainability of the US-led order, on the naivety of engagement with China — demonstrates genuine intellectual courage. His critics argue that he has never fundamentally challenged the PAP government's domestic policies or governance model, suggesting that his "independence" operates within understood boundaries.

10. Outcomes and Evidence

Bilahari's influence is difficult to measure quantitatively — he has not negotiated a treaty, administered a programme, or won an election. His impact is in the realm of ideas, perceptions, and the framing of strategic choices. Nevertheless, several outcomes can be identified:

Shaping the public discourse on Singapore's foreign policy. Before Bilahari's emergence as a public commentator, Singapore's foreign policy was discussed publicly in relatively narrow and formulaic terms. His interventions expanded the vocabulary and deepened the analysis available in the public sphere, making it possible to have more substantive public conversations about strategic choices that had previously been confined to classified briefings and private meetings. This has had a democratising effect on foreign policy discourse in Singapore, even within a political system that remains fundamentally elite-driven.

Articulating Singapore's position on Chinese influence operations. Bilahari's analysis of Chinese influence operations — particularly his argument about the exploitation of ethnic Chinese communities — has been widely cited in academic and policy literature, not only in Singapore but in Australia, the United States, and other countries grappling with similar challenges. His framing has influenced how these issues are discussed and has provided intellectual ammunition for policymakers who wanted to address Chinese influence operations without appearing xenophobic.

Contributing to ASEAN debates. His candid assessment of ASEAN's limitations has contributed to a more honest conversation within the association about what it can and cannot do. While ASEAN officials predictably rejected his "useful fiction" characterisation, the underlying analysis — that ASEAN's value lies in providing a framework for managing great-power competition rather than in its capacity for collective action — has gained wider acceptance.

Influencing younger diplomats and analysts. Multiple younger Singaporean diplomats and foreign policy scholars have cited Bilahari as an influence on their thinking, not because they agree with all his positions but because his analytical framework provides a rigorous and internally consistent lens through which to assess strategic challenges. His willingness to engage publicly with complex questions has also served as a model for a more publicly engaged form of policy thinking in Singapore.

The comparative landscape of Singapore's foreign policy voices. Bilahari occupies a distinctive position in the quartet of major Singaporean foreign policy voices that includes Tommy Koh, Kishore Mahbubani, and Chan Heng Chee. Tommy Koh, the eldest, represents the liberal internationalist tradition — faith in international law, multilateral institutions, and the possibility of a rules-based order. Chan Heng Chee, Singapore's longest-serving Ambassador to the United States, embodies a more measured and diplomatic style of public engagement, offering analysis that is rigorous but calibrated to avoid unnecessary provocation. Kishore Mahbubani represents what might be called "Asian optimism" — the conviction that Asia's rise is transforming the international order and that Western dominance is giving way to a more pluralistic global system. Bilahari, by contrast, represents strategic realism — the insistence that the international system is fundamentally competitive, that cooperation is instrumental rather than normative, and that Singapore's survival depends on a clear-eyed assessment of power rather than appeals to values or institutions. These four voices, taken together, represent the range of Singapore's foreign policy thinking and the tensions within it.

11. What the Archive Has Not Yet Revealed

• Internal MFA deliberations during the Terrex crisis. Bilahari's public commentary during the 2016-2017 crisis with China was substantial, but the internal deliberations within the MFA — the options considered, the positions debated, the instructions issued to Singapore's diplomatic missions — remain classified. Future declassification may reveal the extent to which Bilahari's public statements were coordinated with or diverged from the government's internal strategy.

• The private channel to Beijing. It is widely assumed that Singapore maintained private communication channels with Beijing during the Terrex crisis and the broader period of tension. Whether Bilahari played any role in these private communications — and whether his public statements were intended to complement or contrast with the private diplomatic track — is unknown.

• The relationship with Lee Hsien Loong. The nature of Bilahari's personal relationship with Prime Minister Lee Hsien Loong and the extent to which Lee endorsed, tolerated, or was occasionally surprised by Bilahari's public commentary remain unclear. Given the centrality of the Prime Minister's Office to Singapore's foreign policy, this relationship is key to understanding Bilahari's public role.

• Bilahari's own classified writings. Like all senior civil servants, Bilahari would have produced a substantial body of classified analysis, policy recommendations, and diplomatic cables during his three decades at the MFA. This material, which would illuminate his thinking at key moments — the Asian financial crisis, the post-9/11 reconfiguration, the early stages of China's assertiveness — will not be available until declassification policies make it accessible, if they ever do. Singapore's declassification practices are conservative.

• The full scope of Chinese influence operations in Singapore. Bilahari has been more explicit than any other Singaporean official in describing Chinese influence operations, but his public statements are presumably based on intelligence assessments that contain far more detail than he has revealed. The Huang Jing case was the most public manifestation, but the broader picture of Chinese influence activities in Singapore — their scope, methods, targets, and effects — remains opaque.

• His influence on the Lawrence Wong generation. Whether Bilahari's worldview will continue to shape Singapore's foreign policy under Prime Minister Lawrence Wong and a new generation of leaders, or whether it will be modified by leaders whose formative experiences differ from those of the founding and second-generation leaders, remains to be seen.
