Abstract

The rule of law bears a special meaning in the context of the international legal order, where there is no clear vertical hierarchy or sovereign. The international rule of law strives to curb the excess autonomy of individual states for the common good. Although there is considerable scepticism about whether the international rule of law actually exists, states largely do behave as if international law is truly “law”, and international obligations are also more enforceable now than ever before. But there have been and will be moments when the international rule of law is interrupted by major powers. In an interdependent world that is both capable of and prone to inflicting unimaginable destruction, the strategy for small states unable to defend themselves directly is to create the conditions that will best promote their survival, and that is accomplished by pursuing and promoting the rule of law both domestically and internationally.

In this paper, I would like to share my views on what I perceive to be the natural intersection between law and diplomacy: I am referring to the enduring role of the rule of law in the international legal order, and more specifically in our foreign policy, and I suggest that this has never been more relevant or important than in these uncertain times. But let me begin by visiting an era that was no less troubled or unsettled. That was the time of the Peloponnesian War—a violent and sustained conflict that eventually saw the fall of Athens and the end of the golden age of ancient Greece.Footnote 1

By the summer of 416 bc, the Delian League, headed by Athens, had already been engaged in protracted warfare with the Peloponnesian League, led by Sparta, for fifteen years. Throughout this time, the small but prosperous island of Melos in the Aegean Sea, roughly 110 km east of mainland Greece, had remained strictly neutral. But their shared ethnicity with the Spartans, coupled with the imperialist ambitions of Athens, sufficed to trigger Athenian aggression.Footnote 2 Athens demanded that Melos join the Delian League and pay tribute to Athens, but Melos bravely—or perhaps foolishly—refused. With that, the wrath of the Athenians descended on Melos and the Siege of Melos began. Some 3,400 men, including heavy infantry and mounted archers, rained fire and fury onto the peoples of that island. By winter, Melos had surrendered but this was not enough to quell the rage of the Athenians, who executed the adult men, enslaved the women and children, and took the island for themselves.

In his seminal work, the History of the Peloponnesian Wars, the Athenian historian and military commander Thucydides powerfully dramatized the negotiations between the Athenian emissaries and the rulers of Melos, in an exchange known as the Melian Dialogue. He described the ultimatum given by the Athenian envoys to the commissioners of Melos in these terms: “The strong do what they can and the weak suffer what they must!” The message was clear: justice was a lofty but ultimately irrelevant ideal in a political landscape dominated by the inequality of power.

Moving 2,400 years forward into a comparable landscape, we see the painting of an entirely different picture. In November 1945, just a few months after the end of World War II, Justice Robert Jackson, then serving as lead Prosecuting Counsel, opened the Nuremberg Trials with these immortal words:

That four great nations, flushed with victory and stung with injury, stay the hand of vengeance and voluntarily submit their captive enemies to the judgment of the law is one of the most significant tributes that Power has ever paid to Reason.Footnote 3

I suggest that the contrast between the declarations of Melos and Nuremberg speaks volumes about the progress that humanity has made. The former spoke of might as right, while the latter of the subjugation of might to reason and justice. The road from Melos to Nuremberg is a journey of faith in the law, and indeed, in the rule of law. But that journey continues apace; and my thesis today is that for Singapore, the rule of law is not so much an aspirational ideal as it is an existential necessity.

My essay today has three broad parts. First, I will propose some basic premises on how the rule of law might be understood in the international context. Second, I will discuss whether the rule of law truly exists in the international legal order, and deal with two critiques that are sometimes raised to suggest that it does not. Third, I will explain my view that Singapore's foreign policy as a small state is, and to a significant extent has to be, founded on the promotion and preservation of the international rule of law.

I. THE RULE OF LAW: WHAT EXACTLY IS IT?

To understand the place of the rule of law within the international legal order, we must first understand what the term means. The expression the “rule of law” is often used synonymously with “law” or “legality”, or even “justice”, but such definitions fail to capture its complexity and nuances. Jurists and constitutional theorists have spilt much ink debating the precise scope and content of different conceptions of the rule of law, but the central idea is clear—the rule of law demands that all persons and entities, including states, be equally subject to rules which are publicly promulgated, equally enforced, and independently adjudicated.Footnote 4

If we were to review the historical origins of the rule of law, we will see that the concept was meant to be applied to states, in respect of matters falling within their legal systems, and in particular to address problems associated with an overly powerful centralized authority, so as to preserve space for individual autonomy even under the authority of the sovereign.Footnote 5 Thus, concepts such as the separation of powers, which is often regarded as central to the rule of law, exist comfortably within a vertical hierarchy involving a powerful sovereign.Footnote 6

But when we speak of the rule of law in the context of the international legal order—meaning the application of the concept between states—some change of perspective is necessary. There is no clear vertical hierarchy or sovereign to speak of. The international legal order is premised on a different, and some might say the exact opposite, concern: that where authority is decentralized and atomistic, individual sovereign states are sometimes in a position to exert more autonomy than the common good can tolerate. Here, the concern is not to prevent the overreach of the central authority in order to preserve the autonomy of the individual, but rather to curb the “excess” autonomy of individual states in order to preserve the international legal order, for the sake of the common good.Footnote 7

Writing in 1961, William Bishop put forward an elegant summary of what the international rule of law entails. In his view, the international rule of law has the following components:Footnote 8

… reliance on law as opposed to arbitrary power in international relations; the substitution of settlement by law for settlement by force; and the realisation that law can and should be used as an instrumentality for the cooperative international furtherance of social aims, in such fashion as to preserve and promote the values of freedom and human dignity for individuals.

II. THE INTERNATIONAL LEGAL ORDER: DOES THE RULE OF LAW EXIST ON THE INTERNATIONAL PLANE?

Bishop's definition is useful as far as it goes, but, as with all definitions, it describes but does not prove. There remains considerable scepticism about whether the international rule of law, intelligible though it might be as a theoretical concept, actually exists. Some scholars have argued that international law is “ultimately limited by power, politics and the rule of force”,Footnote 9 and that the rule of law is a mere ideal, a “leitmotif in international relations”.Footnote 10 One scholar has memorably remarked that the rule of law seems so extraneous to the actual practice of international law, which is wrought and riven by realpolitik,Footnote 11 that it may almost be likened to “an accidental tourist at a diplomatic conference”.Footnote 12

This scepticism typically stems from two critiques. First, it is said that international law is not really “law” in any meaningful sense because there is nothing on the international plane that corresponds to the coercive power that a state possesses over its citizens. Second, even if international law is really “law” in some sense, it does not meaningfully affect state behaviour because there is no system for ensuring that states comply with international legal norms. Let me address both critiques in turn.

A. Is International Law Really Law?

The first critique is backed by what has been called the “Austinian assumption”, after the English legal theorist John Austin. The argument proceeds in this manner: Laws are commands emanating from a sovereign and backed by the threat of enforcement using the sovereign's organized might. Since such a sovereign does not exist on the international plane, international law cannot be law in any meaningful sense.Footnote 13

This command theory of law has been pervasively criticized for its oversimplification of law, and is no longer widely held. H.L.A. Hart famously argued that the essence of law lies instead in the “internal aspect” of rulesFootnote 14—that is, an attitude of acceptance in those who abide by them, and a reason for criticism of those who deviate from them. In other words, it is the normativity of rules that is the defining quality of legal obligation. I will return to the critical issue of normativity later.

In addition, it is not clear that even domestic—much less international—law fulfils the Austinian criteria of “law” all the time. Roger Fisher has forcefully argued that much of domestic law, too, does not depend upon the sovereign's might. For example, in the critical context of proceedings for judicial review brought against the government, one might argue that the government complies with decisions that are not in its favour not because of any meaningful coercive force or power it possesses over itself, but rather because it chooses to comply with the law,Footnote 15 or because it feels compelled to do so by the political pressures of the ballot box. Even in cases involving private citizens, it has been pointed out that rules concerning matters such as contractual obligations are obeyed not because of the state's coercive power but because they are perceived to be just and necessary for the orderly functioning of society.Footnote 16

I suggest that, if we were briefly to survey the state of international compliance today, we would find that states, largely, do behave as if international law is truly “law”, notwithstanding the lack of a law-giving or coercive international sovereign. This can be seen in the following ways: first, the sources of international law are well recognized;Footnote 17 second, the rules governing the creation and effect of written legal norms such as treaties are widely accepted;Footnote 18 and third, states generally do conduct their affairs according to the strictures of and the expectations inherent in international law. Some have claimed that great powers do not comply with the rulings of international courts when it is not in their interests to do so,Footnote 19 but quantitative and qualitative analysis has shown that final judgments of international courts do receive a great deal of deference and compliance, and that instances of outright defiance are few and far between.Footnote 20

It therefore appears that the oft-quoted observation of Louis Henkin still holds true today—that “almost all nations observe almost all principles of international law … almost all of the time”.Footnote 21 Viewed in this light, despite the absence of a coercive sovereign, the critique that international law is without force is simply inconsistent with observable reality and must therefore be discarded.

B. The Increasing Enforceability of International Obligations

I turn to the second critique, which concerns the enforceability of international legal obligations. I believe that this critique—if it ever were true—surely can no longer stand today, because international obligations today are perhaps more enforceable than ever before. I will illustrate this by focusing on just four different areas of comparatively recent legal development.

1. International courts and tribunals

First, the world has seen a multiplication of permanent and active international courts and tribunals, presided over by independent judges who apply procedural and substantive rules of international law. While only a few such institutions existed as recently as thirty years ago, there are more than twenty international courts and tribunals today, ranging from the well-known International Court of Justice [ICJ] and the European Court of Human Rights [ECtHR] to the administrative tribunals of international organizations such as the Asian Development Bank [ADB] and the North Atlantic Treaty Organization [NATO].Footnote 22

Not only are there more international courts today, these courts are also doing more. They have collectively seen a tenfold increase in their case-load and judicial output in recent decades, and that has led in turn to a growing and vibrant body of international law.Footnote 23 This is significant because as Judge of the ICJ Sir Hersch Lauterpacht observed in 1958, the “very existence of the [ICJ], in particular when coupled with the substantial measure of obligatory jurisdiction already conferred upon it, must tend to be a factor of importance in maintaining the rule of law”.Footnote 24

Moreover, the reach of these tribunals has also expanded over time. A striking example of this is the advisory opinion of the ICJ delivered in February this year, in which the Court held that the decolonization of Mauritius in 1968 had not been lawfully completed because the UK had wrongfully detached the Chagos Islands from Mauritius.Footnote 25 Notably, the ICJ decided that it had jurisdiction to provide an advisory opinion on this matter, notwithstanding that opinions on bilateral disputes can typically only be issued with the consent of both parties, and such consent had not been given by the UK in this instance.Footnote 26 The ICJ sidestepped the problem by framing the issue as one pertaining to the “broader frame” of decolonization rather than a territorial dispute, emphasizing that the United Nations [UN] General Assembly has had a “long and consistent record in seeking to bring colonialism to an end”.Footnote 27

It has been observed that the ICJ's reasoning evinces its increasing tendency to give precedence to multilateral interests over bilateral concerns, as it embraces its role as the UN's “principal judicial organ”.Footnote 28 Although advisory opinions are not legally binding on states, they do carry considerable weight as a statement of the international legal position.Footnote 29 In the Chagos Islands case, the UN General Assembly welcomed the ICJ's advisory opinion later in May, affirming in a resolution that “respect for the Court and its functions, including in the exercise of its advisory jurisdiction, is essential to … an international order based on the rule of law”.Footnote 30

2. Privatization of international law

Second, the enforceability of international legal obligations has been supported by the growing privatization of international law. This is reflected in both the increasing focus of international law on the rights and interests of individuals, reflected in such issues as dual nationality, consular assistance. or the detention of foreigners,Footnote 31 as well as the growing procedural capacity of individuals to hold states accountable for violations of international law, on matters extending from human rights to economic and social interests.Footnote 32

This increasing empowerment of individuals and enterprises on the international plane is most notable in the area of investor-state dispute settlement [ISDS], which allows foreign investors to bring claims directly against the host state, usually by way of arbitration.Footnote 33 ISDS mechanisms tend to be less cumbersome and more cost-effective than conventional state-to-state dispute resolution. That has fuelled the growing popularity of ISDS: in the fifteen-year period from 1987 to 2002, some 100 claims were initiated in investor-state arbitrations, but in the decade that followed, a total of 568 claims were filed.Footnote 34

It is true that ISDS has faced increasing political pushback in recent years, arising primarily from the concern that tribunals are impinging on state sovereignty by deciding matters of domestic policy that ought to be reserved to national governments and courts.Footnote 35

At the same time, the UN Conference on Trade and Development has warned of deficiencies in ISDS, including its “skyrocket[ing]” costs, long timeframes, lack of control over arbitral procedures, and general concerns about the legitimacy of the process;Footnote 36 and others have suggested that ISDS suffers from a “legitimacy crisis” because its outcomes are reached through a private and non-transparent process but affect matters of public interest such as the economy and the environment.Footnote 37

Doubts over the viability of ISDS came into sharp focus in the decision of the Court of Justice of the European Union [CJEU] in Achmea in 2018,Footnote 38 which, some have suggested, marks the “beginning of the end” for ISDS in Europe.Footnote 39 In Achmea, the CJEU ruled that an arbitration clause in a bilateral investment treaty between the Netherlands and Slovakia was incompatible with EU law because the Treaty on the Functioning of the EU did not permit the removal of disputes concerning the application or interpretation of EU law from the EU's judicial system. Although it is too early to ascertain the full impact of Achmea,Footnote 40 it now appears to be difficult to enforce ISDS awards before the EU's domestic courts,Footnote 41 and that is particularly unfortunate for European investors, who have been the most frequent users of ISDS.Footnote 42

While headwinds blow in the way of the continued growth of ISDS, there remain many who are committed to preserving its contribution to the maintenance of the international legal order. Singapore, for one, has participated actively in the international dialogue to develop a fair, workable, and cost-effective ISDS framework.Footnote 43 New ideas include the establishment of a body to hear appeals against decisions of arbitral tribunals, and even the replacement of investor-state arbitration with a permanent investment court so as to improve the consistency and correctness of decisions and guarantee the independence of adjudicators.Footnote 44 The global interest in ISDS has also led the UN Commission of International Trade Law to task one of its Working Groups to make recommendations on reform.Footnote 45

Despite its shortcomings, I believe that ISDS has the potential to prevent instances of more powerful states favouring their own nationals through diplomatic or military interventions in weaker host states.Footnote 46 In many ways, this embodies the very ideal of the rule of law. With suitable refinements, investment disputes will prove capable of resolution through fair, neutral, and regulated processes, insulated from the influences of state power or corporate interests.

3. International sanctions

Third, enforcement may come in the form of sanctions that interrupt flows of trade and commerce or even sever diplomatic relations. The UN Security Council is empowered by Article 41 of the UN Charter to decide the measures needed to give effect to its decisions, and to call upon members of the UN to apply those measures. Over the past fifty years, the UN Security Council has established thirty sets of sanctions,Footnote 47 amongst the most prominent of which are the near-total financial and trade embargo imposed on Ba'athist Iraq over the span of almost two decades, following its invasion of Kuwait in 1990,Footnote 48 and the institution of nearly a dozen embargoes on North Korea, condemning its nuclear pursuits.Footnote 49

The justifiability and efficacy of sanctions are the subject of continued controversy. Some have denounced economic sanctions as a “form of collective punishment that is in total contradiction to the basic principles of justice and human rights”.Footnote 50 While the sanctions against Iraq are generally regarded as having been effective in limiting the availability of arms to the regime, it is estimated that more than half a million Iraqi children died from malnutrition and disease as a result.Footnote 51 The effectiveness of sanctions can also be uneven. A study has shown that fifty-six countries violated UN sanctions against North Korea in 2018, whether deliberately or inadvertently.Footnote 52 Others argue that these sanctions have in fact done little to deter Pyongyang from its nuclear ambitions, conditioned as the country has become to the human costs of the sanctions.Footnote 53

Quite apart from their effectiveness in coercing or punishing targeted states, sanctions undoubtedly have an important communicative function. They remain a potent signal of the international community's condemnation of norm violations and its willingness to act powerfully, but peacefully, to maintain the international rule of law.

4. Soft enforcement

Fourth, we are seeing an increase in what can be called “soft enforcement”, by which states review and critique the compliance of other states with their international law obligations. Perhaps the best known of these mechanisms is the Universal Periodic Review [UPR] organized by the UN Human Rights Council. Every four years, states submit “national reports” declaring the actions they have taken to improve their human rights situations. UN Member States then pose questions and make recommendations to the state under review, and these are collated in an “outcome report”. At a subsequent review, the state has to give an account of the progress it has made in implementing those recommendations.Footnote 54

It is true that the UPR is a political process and that its recommendations are not legally binding. It should also be acknowledged that aside, possibly, from a core of rights that are widely accepted, there will be considerable differences of perspectives in a multi-polar and diverse world. To take just one example, the debate in Europe on the use of headscarves by Muslim women would seem quite foreign to most of us in this part of the world. Nonetheless, the UPR has been fairly credited for promoting the protection of human rights. Out of over 60,000 recommendations made over the past three UPR cycles, more than seventy percent have been supported by the states under review.Footnote 55 The UPR process has even had the legal effect of building opinio juris—or consensus on norms of international law—in the field of international human rights.Footnote 56

Collective soft enforcement is also a key feature of treaties on environmental protection. An example is the Montreal Protocol on Substances that Deplete the Ozone Layer, which has been ratified by no less than 197 states and hailed by the former UN Secretary-General Kofi Annan as “perhaps the single most successful international agreement to date”.Footnote 57 Such a demonstration of multilateralism is so very welcome at a time when climate change and the environment present some of the gravest challenges facing humanity. Central to the success of the Protocol has been its “noncompliance procedure”, which encourages compliance through the “collective reaction” of other Contracting States and the “mobilization of shame”, rather than confrontation and formal dispute settlement.Footnote 58 A state's reasons for non-compliance are placed before a meeting of the other Contracting States, which then decide how to assist the non-complying state to carry out its obligations. This “encouragement-based approach”Footnote 59 has been lauded as a “great step forward in strengthening … collective state compliance … [with] international environmental law”.Footnote 60

C. The Existence of the International Rule of Law

Let me pause to draw these threads together and revisit the question I posed earlier: Does the international rule of law exist in any real or binding way today? Has the world retreated from its pledge in the preamble of the UN Charter to “establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained”?Footnote 61

I suggest that, although there are moments when it has been greatly strained, sometimes almost to breaking point, the international rule of law remains alive today. I say this for three broad reasons. First, the international rule of law is sustained by the rule of international law. I have explained that the body of international law has perhaps never been as comprehensive, accessible, or vibrant as it is today, fed by the tributaries of various international courts and tribunals, and backed by multiple means and levels of enforcement. The interconnectedness of the world today has fostered an unprecedented level of interdependence, with the consequence that no state can sustainably or meaningfully operate beyond the net of international obligations; nor can it suffer for long—at least not without immense cost—the weight of international sanctions. A country that repeatedly repudiates and disrespects international law will also inevitably be labelled as a pariah and suffer the consequences of diplomatic isolation and global disapproval.Footnote 62

The second reason is this: the enforceability of international law has been promoted by its normative value. Law is an instrument for changing behaviour because it has an important constitutive effect. By shaping our conceptions of what is right and wrong, it moulds our identities and guides our preferences.Footnote 63 This means that it is in fact normativity that paves the way for enforcement, not the other way around.Footnote 64 To put it another way, collective actions become effective when and because they are seen as being the right response. James Brierly illustrates the point with the example of a police force, noting that “it is not the existence of a police force that makes a system of law strong and respected, but the strength of the [system of] law that makes it possible for a police force to be effectively organized …”Footnote 65

This means that, as long as a sufficiently large majority of the international community values and sustains the international rule of law, the normativity of international law will encourage the continued compliance of states. As our former Foreign Minister Mr S. Dhanabalan once said, “accepted legal prohibitions against the use of force … ensures that states can only resort to force with a bad conscience”.Footnote 66 The need to justify the use of force is itself a form of constraint, because no state wishes to be seen as a bandit roaming the highway of the international rule of law.

The field of international criminal justice, and the move towards what has been called the “end of impunity”, provides a sterling example of how normativity changes perspectives, influences behaviour, and even drives enforcement. One of Nuremberg's enduring contributions to international criminal jurisprudence was its rejection of the notion, quite widely accepted until then,Footnote 67 that individuals could not be put on trial for acts committed by states. This was an untenable position because, as the Tribunal remarked, “[c]rimes against international law are committed by men, not by abstract entities, and only by punishing individuals who commit such crimes can the provisions of international law be enforced”.Footnote 68 That has paved the way for the indictments of such individuals as Jean Kambanda of Rwanda, Slobodan Milosevic of Yugoslavia, and Augusto Pinochet of Chile.

And the third reason is this: even when normativity fails, and the light of reason and friendship dims, we can turn to self-interest to sustain international peace and order. The reality of a globalized world means that, in the long run, it is in the best interests of all states, regardless of their size and swagger, to play by the rules. Harold Koh has observed that great powers that seek domination by might have historically become victims of “imperial overstretch”, “plagued by external debt, national exhaustion and internal dissension”. The more effective use of power and strength is to influence and persuade by espousing the common values of international law, and thereby gaining legitimacy through “smart power”.Footnote 69 The inescapable reality is that outright unlawfulness will lead to catastrophe for all, in the form of destructive wars, reprisals without winners, and a trail of casualties. And so the international rule of law emerges as a critical reality—a survival strategy for the vulnerable, an essential condition for those seeking to assert moral leadership, and the very fabric holding together an interdependent world.

But what happens in the moments when the international rule of law cracks, and the scales of principle and solidarity fall away? Even in a climate of general respect for the international rule of law, there will be times when powerful states decide that the balance of self-interest tilts in favour of aggression rather than peaceful co-existence and respect for the law. When the Soviet army invaded Afghanistan in December 1979, the world reeled from the flagrant violation of international law. The UN General Assembly passed a resolution at an emergency special session, deploring Soviet aggression and calling for a return to “respect [for] sovereignty, territorial integrity and political independence”.Footnote 70 Just a month before that, Iranian students took over the US Embassy in Tehran, marking the beginning of the Iran hostage crisis. The Iranian authorities, under the leadership of Supreme Leader Ayatollah Khomeini, supported the hostage-takers. The US appealed to the ICJ for provisional measures and the ICJ ordered the immediate release of the hostages on the basis that there is “no more fundamental prerequisite for the conduct of relations between States than the inviolability of diplomatic envoys and embassies”.Footnote 71 Even so, it was not until 444 days later, with the passing of the Algiers Accords and a series of concessions by the US, that the hostages were finally released.Footnote 72

These and other moments through history reveal that the narrative of the international rule of law is not uninterrupted, just as domestic laws are sometimes breached. But within these interregnums, the very existence of small states may hang in the balance. As Mr Rajaratnam said on the occasion of Singapore's admission to the UN in 1965, “world peace is a necessary condition for the political and economic survival of small countries, like Singapore … because we have not the capacity to make war on anybody”.Footnote 73 How can small states preserve their sovereignty during these moments of anarchy? What kind of appeal can they make when more powerful states decide that the spoils of war are worth the price of aggression?

III. THE FOREIGN POLICY OF SMALL STATES: WHAT DOES ALL THIS MEAN FOR SINGAPORE?

This brings me to the final part of my essay today and also to the present moment, when the world once again seems to be at a point of inflexion. Recent years have seen a global revival of nationalism in the political landscapes of advanced economies.Footnote 74 Politicians have campaigned and won on protectionist agendas which have then, at times, been translated into policy. In its wake, some say we have seen something of a “gradual decay of the international order that emerged after World War II”Footnote 75 and increasing disregard for the international rule of law, which seems susceptible to being subordinated to the vicissitudes of domestic politics. Countries seem to adopt a zero-sum mentality in eschewing multilateral agreements as “shackles on sovereignty and a burden on economic growth”.Footnote 76

What does this “gradual decay of the international order”Footnote 77 mean for small states such as ours? How should we navigate an increasingly polarized world order that seems more ready to resort to threats, trade wars, and tribalism?Footnote 78 I believe that the answer lies in five core principles that frame Singapore's foreign policy. These were identified by the Minister for Foreign Affairs, Dr Vivian Balakrishnan, about two years ago in a speech to the Ministry of Foreign Affairs [MFA],Footnote 79 and have also been points of emphasis throughout the lectures in the S. Rajaratnam Series. Let me take a moment to outline them.

The first principle is the need to sustain our successful and vibrant economy, because our international standing is founded in part on the policies that have made us prosperous and lent us relevance as a centre of trade and finance. The Minister Mentor Mr Lee Kuan Yew observed at the beginning of his S. Rajaratnam Lecture in 2009 that Singapore's “economic imperative” is to ensure “that other countries have an interest in our continued survival and prosperity as a sovereign and independent nation”.Footnote 80 Hence, an effective foreign policy must begin at home.

Second, we must maintain a strong and respected defence force that can deter potential hostility. At the 2012 S. Rajaratnam Lecture, then Deputy Prime Minister Mr Teo Chee Hean remarked that diplomacy and defence in Singapore are “twins”, with the Singapore Armed Forces as the “final guarantor of our sovereignty”.Footnote 81 In turn, our defence force must be backed by a society that is resilient, stable, and united in the face of external threats.Footnote 82

Third, we must continue to expand our network of political and economic relationships. This involves being an active and contributing member of multilateral groups such as ASEAN, the Forum of Small States, and the Global Governance Group. These fora provide a broader stage upon which we can advocate our interests, influence regional policies, and, in this way, have a louder voice in the global marketplace. In the same vein, at a recent reception for members of the Forum of Small States, Prime Minister Mr Lee Hsien Loong spoke emphatically about the need for small states to “make common cause”, coming together to “amplify [their] influence in the world”.Footnote 83 Closely tied to this is the fourth principle, which is our promotion of an international legal order that respects reason rather than force. Over the years, we have done much good work in this sphere, ranging from our contributions to the UN Convention on the Law of the Sea in 1982 and the facilitation of key sections of the Paris Agreement on Climate Change in 2015, to our efforts in spearheading the recent Singapore Convention on Mediation.

The fifth and final principle is the need for consistency and credibility in our interstate relationships, or being what the Foreign Minister called an “honest broker” in international affairs: an independent, non-aligned, and constructive member of the international community that “cannot be bought, nor … bullied”.Footnote 84 That involves committing to principle, steadfastly adhering to our international obligations, and—as Professor Jayakumar pointed out in the 2010 S. Rajaratnam Lecture—equally “insist[ing] that agreements entered into in good faith should be honoured” by others.Footnote 85

I suggest that all of these principles—relevance, defence, diplomacy, legality, and consistency—are intimately associated with the rule of law, whether at the domestic or international level. Our economic success is underpinned by a legal system that is fair, efficient, and well respected. The effectiveness of our national defence is founded on a society that is stable, orderly, and law-abiding. We interact with other states and participate in international organizations in a manner consistent with our international obligations, and we expect other states to do the same. And the “strategic predictability”Footnote 86 that underpins our credibility as a trusted and neutral voice is inextricable from our sustained loyalty to international law.

It is for all these reasons, and at all these various levels, that the pursuit of the rule of law lies at the very heart of our foreign policy. The rule of law is and has been the lynchpin of our economic success and this has earned us the world's respect. It is the ethical code that governs our conduct on the international stage. And it is the message that we take to an increasingly fractious and divided world that appears at times to be retreating from multilateralism. I suggest that the rule of law is also the strategy that will sustain us in an age of interdependence. As I mentioned earlier, no state can afford to violate the rights of others without risking exclusion from the international community, or having its rights violated in the same way by some other state. The best strategy for small states unable to directly defend themselves is to create the conditions that will best promote their survival—and that is the world of Nuremberg, not of Melos.

In the Melian Dialogue, the Melian commissioners appealed first to morality, examining whether the Athenians had “right on [their] side”. The Athenian envoys had little difficulty in admitting that what they had was might and not right. The Melians suggested that they were favoured by the gods as “just men fighting against unjust”, but the Athenians countered that the gods would do just as the Athenians did, and “rule wherever they [could]”. Finally, the Melians argued that the Spartans would come to their aid, as a people of “common blood”. The Athenian envoys countered that the Spartans would not risk defeat at the hands of the superior Athenian navy. Shocked by the Melians’ “great blindness of judgment”, the envoys returned to the army, which then fell upon Melos.Footnote 87

The moral of Melos is not bravery in the face of overwhelming odds, but the need to remain deeply conscious of geopolitical realities. To be fair, Melos faced a very different world order; and in a far less interconnected region dominated by two superpowers, a small island was bound to struggle. Even so, the Melians’ mistake was perhaps to rely on fickle things—like the persistence of good relations, faith in good fortune, or the backing of a good neighbour. Truth be told, small states can never survive on pious hope alone. Without might on their side, they must rely on their own wits and ingenuity. As the Minister Mentor said in his lecture:

[f]riendship, in international relations, is not a function of goodwill or personal affection … Small countries perform no vital or irreplaceable functions in the international system. Singapore has to continually reconstruct itself and keep its relevance to the world and to create political and economic space.Footnote 88

Over the last fifty-four years, we have worked hard to carve out that relevance and that space by a considered strategy rooted in a sustained commitment to the rule of law, and it has served us well. But what of the future? I believe this same strategy must continue to guide us.

I suggest that, across the passage of the years from the Peloponnesian War to the present, three mega trends have shaped the world. First, a world that was once parochial and insular has become hyper-connected and highly interdependent, and it rapidly continues to converge. The second is the extraordinary advancement of human knowledge and, with it, our ever greater expertise in the science of destruction. World War II brought death on an unprecedented scale, effected by automatic rifles, gas chambers, and aerial bombardments, and it culminated in the atom bomb. During the Cold War, the development of second-strike capability in retaliation to a nuclear attack supported the strategy of Mutual Assured Destruction or just “MAD”. The Battle of Baghdad in 2003 showcased the killing prowess of modern technology as computer-guided missiles brought the “shock and awe” of the Coalition attack to the living rooms of billions.

These two trends—the inescapable reality of interdependence and the ability of even a second-tier power to annihilate its enemy—have led inevitably to the third and more recent, but no less obvious, trend, which is the increasing realization of the need to regulate the behaviour of states through law. Law alone provides a measure of assurance, of predictability, and of order. In the final analysis, I suggest that fidelity to the law is the only acceptable solution. The alternative is a descent into anarchy; and that, in a world that has become so interdependent and at the same time so able to inflict destruction on an incalculable scale, spells doom not only for small states but indeed for much of humanity.

IV. CONCLUSION: STAYING THE COURSE

Our future then lies not in the naive tactic of tethering our fate to whoever we think is the strongest power, for that will mean reducing ourselves to the status of a vassal. And in any case, history teaches us that what goes around, comes around. Merely a decade after the Siege of Melos, Athens was defeated by Sparta, though that was ten years too late for the unfortunate Melians. Rather, our future lies in intentionally, deliberately, and continually carving out our space as a relevant, rational, and consistent partner in our international dealings, and displaying an inerrant and insistent commitment to the international rule of law, even if this might prove at times to be inexpedient. The long arc of history teaches us that a mighty power might be able to bully some of the rest of us most of the time, and most of the rest of us some of the time. But when we find ourselves at the receiving end of such bullying, we should pull all the levers of our foreign policy strategy and remain confident that, in today's world, no power can bully all of us, all of the time.

The drama of Thucydides’ ancient Greece has long faded away, as have the passions of the Nuremberg Trials. We now inhabit a post-Nuremberg, Westphalian twenty-first century.Footnote 89 The relative stability that we have enjoyed on the domestic and international front has been due in large part to the respect for the rule of law, but we cannot and must not take this for granted. Against the challenges of our own age, I suggest that we must continue to hold ourselves out not only as faithful adherents to, but also as staunch defenders of, this ideal.
