International Law Is Powerful in Principle but Weak in Enforcement

International law is one of the great promises of modern civilisation. It says that power must be restrained, sovereignty respected, civilians protected, treaties honoured and war subjected to rules. Yet it contains a contradiction that becomes most visible during major crises: international law can be powerful enough to define what states should do, but too weak to ensure that powerful states actually do it.

States invoke the United Nations Charter when their own territory or interests are threatened, yet may reinterpret legal principles when allies are accused of violating them. Governments demand accountability for adversaries while becoming more cautious when strategic partners face similar allegations. Human-rights principles can be defended strongly in one conflict and treated as politically inconvenient in another. The problem is therefore not that international law has no influence. It is that enforcement depends heavily on state consent, political will, institutional authority and the distribution of global power.

This tension has become more important because international law now operates in a world where power is changing form. Territory and military force still matter, but so do sanctions, cyber operations, artificial intelligence, digital infrastructure, technology standards, financial networks and control over data and compute. International law must increasingly regulate forms of coercion that the post-1945 legal order was never designed to manage fully.

Why International Law Is Under Greater Stress

The contemporary international system has pushed legal questions into everyday geopolitics. The Russia-Ukraine war has revived debates over aggression, territorial integrity and the laws of armed conflict. The Gaza conflict has intensified arguments over civilian protection, proportionality, occupation, humanitarian access, genocide allegations and international criminal accountability. Maritime disputes in the South China Sea raise questions of sovereignty, navigation and treaty interpretation, while sanctions, cyber operations and refugee movements are testing other areas of law.

International courts and tribunals therefore receive far greater public attention than they once did. The International Court of Justice can clarify obligations between states, while the International Criminal Court can pursue individual criminal responsibility within the limits of its jurisdiction. But legal attention is not the same as legal enforcement. Courts generally lack independent coercive machinery capable of forcing powerful governments to comply.

This creates a recurring credibility problem. If international law appears strict when applied to weaker states but negotiable when powerful states or their allies are involved, trust in the system declines. The question then becomes not whether legal rules exist, but whether they operate consistently enough to command respect.

The Modern Legal Order Was Built to Restrain Power

Modern international law emerged from several historical traditions, including European state practice, colonial encounters, treaty systems, the experience of two world wars, decolonisation and the creation of international organisations. The United Nations Charter represented one of the most important turning points because it attempted to place legal limits on the use of force while formally recognising the sovereign equality of states.

International humanitarian law developed another layer by regulating how wars are fought even when war itself cannot be prevented. The Geneva Conventions and related rules sought to protect civilians, prisoners, medical personnel and others who are not directly participating in hostilities. Human-rights treaties subsequently expanded the idea that sovereignty does not give governments unlimited freedom over the people living under their authority.

Decolonisation transformed the legal system further. Newly independent states demanded sovereign equality, non-interference, self-determination and an end to structures created under imperial domination. International law consequently became not only a language used by major powers but also a legal shield through which weaker states could defend their independence.

Yet the Cold War quickly demonstrated the limits of the post-war promise. Superpowers used vetoes, proxy conflicts, military interventions and alliance politics to protect their interests and partners. After the Cold War, optimism about a more rules-based order increased, but military interventions in Kosovo, Iraq, Libya and elsewhere reinforced suspicions — particularly across the Global South — that legal principles could still be applied selectively.

The unresolved question has remained the same: can international law genuinely bind the powerful, or does it operate most effectively when power already permits enforcement?

International Law Is Not One Single Body of Rules

The phrase “international law” can become too abstract unless its major components are separated. The UN Charter regulates fundamental questions involving the use of force, self-defence, sovereignty and collective security. International humanitarian law governs conduct during armed conflict and attempts to limit suffering even when political efforts to prevent war have failed.

Human-rights law establishes obligations concerning the treatment of individuals, while treaty law provides rules for agreements between states. Maritime law governs territorial seas, exclusive economic zones, navigation and other ocean-related rights. International criminal law addresses individual responsibility for the gravest crimes, while diplomatic law protects embassies, diplomats and official communications.

These branches operate differently. Some rules are enforced through domestic courts. Others depend on international tribunals. Some rely heavily on reciprocity because states obey them partly because they expect others to do the same. Others are politically contested because enforcement can directly challenge governments or military operations.

The weakness of international law is therefore not uniform. In many routine areas, compliance is extensive. The greatest problems emerge when legal rules collide directly with high-stakes geopolitical interests.

Law as Shield, Sword and Stage

A useful way to understand international law is to see it performing three different functions.

Law as a shield protects states and individuals by creating rules against aggression, unlawful detention, mistreatment, territorial seizure and other abuses. Smaller states have particular reason to support this function because legal protections can strengthen their position against stronger neighbours.

Law as a sword appears when governments use legal arguments against rivals. States accuse one another of treaty violations, unlawful military action, human-rights abuses, illegal occupation or breaches of maritime rules. These claims may be legally legitimate, but they can also become instruments of geopolitical competition.

Law as a stage describes international courts, UN forums and legal processes as places where global legitimacy is contested. Even when a judgment cannot be enforced immediately, legal proceedings create records, shape public opinion and influence how conduct is remembered internationally.

This third function explains why international law remains relevant even when enforcement is weak. A ruling may not stop a war, but it can affect diplomatic support, reputational costs and future negotiations. Legal language helps transform raw political accusation into arguments that can be examined against common standards.

Sovereignty Is Both Protected and Limited by International Law

Sovereignty lies at the centre of the international legal order. The system protects states against aggression and external interference, but modern law also rejects the idea that sovereignty gives governments unlimited freedom inside their own borders.

This creates one of international law’s deepest tensions. States want protection from intervention, yet international human-rights rules impose obligations concerning how governments treat individuals. Governments therefore frequently disagree over where legitimate international scrutiny ends and political interference begins.

For countries with histories of colonialism, this question is especially sensitive. Humanitarian or human-rights language can appear principled in one context but look like a justification for political pressure in another.

The challenge is to preserve both principles: sovereignty cannot become a licence for serious abuse, but human-rights language cannot become an unrestricted justification for powerful states to override weaker ones.

Enforcement Is the Weakest Part of the System

Domestic law normally operates through courts backed by police and state authority. International law lacks an equivalent world government. Courts may issue judgments, but implementation frequently depends on states themselves.

This is why consent matters so much. States decide which treaties they join, which court jurisdictions they accept and how far they cooperate with investigations. Some international obligations are stronger than others, but enforcement still depends heavily on national institutions and political pressure.

The UN Security Council can provide greater coercive authority, including sanctions and other measures, but the veto power of its five permanent members introduces structural inequality. When the interests of a permanent member or close ally are involved, collective enforcement can become politically impossible.

The result is an unusual legal system: states accept rules because the system provides predictability and legitimacy, yet the strongest actors retain substantial ability to obstruct enforcement when their core interests are involved.

Selectivity Is the Greatest Threat to Legal Legitimacy

International law can survive occasional violations. No legal system achieves perfect compliance. The deeper danger comes when violations appear to be judged according to the identity of the perpetrator rather than the nature of the conduct.

If governments condemn territorial aggression in one region while finding excuses for it elsewhere, the principle of territorial integrity begins to look political rather than universal. If civilian suffering produces demands for accountability in one conflict but strategic silence in another, human-rights language loses credibility.

This selectivity has consequences beyond individual disputes. Smaller states may conclude that legal protections are reliable only when major powers find them convenient. Governments facing criticism may dismiss legitimate allegations as geopolitical manipulation. Citizens may see international institutions as extensions of power rather than neutral guardians of law.

The damage is therefore cumulative. Every visibly inconsistent application weakens the authority of future legal claims.

Great-Power Politics Is Built Into the System

The institutional architecture of the United Nations reflects the power distribution that existed at the end of the Second World War. Permanent membership and veto power in the Security Council gave major powers a privileged position in collective security.

That arrangement had a political logic. The UN could not function effectively if the strongest military powers simply rejected the institution altogether. The veto was therefore partly designed to keep them inside the system.

But the price was structural inequality.

The same states that participate in writing and enforcing international rules possess exceptional capacity to block action affecting themselves or important partners. This produces the recurring perception that legal accountability is strongest where geopolitical protection is weakest.

Reforming this structure is extremely difficult because the states benefiting most from the existing system have little incentive to surrender their privileges.

India’s Relationship With International Law Is Built Around Sovereignty

India’s approach to international law reflects its colonial history, territorial concerns and experience as a major developing country. New Delhi has traditionally defended sovereign equality, non-interference, peaceful dispute settlement and the principle that international institutions should not become tools of great-power domination.

This makes India cautious about doctrines that permit external intervention under broad moral or humanitarian arguments. The memory of colonial rule makes sovereignty more than an abstract legal concept. It represents protection against external political control.

At the same time, India benefits significantly from a functioning international legal order. Territorial integrity matters to India. Diplomatic immunity protects Indian missions. Maritime law affects trade and security across the Indian Ocean. Treaty law underpins economic agreements. Rules concerning aviation, shipping, telecommunications and international commerce are essential to India's integration with the world.

India is therefore not anti-international law. Its deeper concern is selective international law.

India Faces a Sovereignty-and-Rights Dilemma

India’s diplomatic challenge is to reconcile two positions that can sometimes pull in different directions. It wants strong legal protection for sovereignty and territorial integrity, but it also wants to be seen as a responsible power committed to human dignity and global norms.

An overly rigid sovereignty-first approach can make India appear indifferent to serious abuses elsewhere. An excessively interventionist position could undermine the non-interference principles India has historically defended and potentially create precedents that New Delhi itself would find uncomfortable.

The more credible position is principled realism. India can oppose aggression, support humanitarian law and defend civilian protection while remaining cautious about coercive intervention lacking broad legal legitimacy.

It can support accountability while insisting that the same standards apply to friends and adversaries.

India’s argument should therefore be that sovereignty and rights cannot be protected through selectively enforced rules.

India Needs Stronger Legal Diplomacy

As India’s geopolitical weight increases, international law expertise becomes a strategic capability. Legal interpretation influences maritime disputes, trade negotiations, sanctions, investment agreements, technology regulation, cyber operations, climate negotiations and the rules surrounding conflict.

India therefore needs deeper institutional expertise in treaty negotiation, international litigation, maritime law, international humanitarian law, technology governance and dispute settlement. Universities, think tanks, government departments and diplomatic institutions should produce larger pools of specialists capable of shaping international legal debates.

Representation also matters. Countries that participate actively in international courts, standard-setting bodies and treaty negotiations gain greater influence over how future rules are interpreted.

International law should not be treated merely as something India reacts to when disputes arise. It should become an area in which India actively shapes the rules.

Technology Is Creating a New Legal Frontier

The next major stress on international law will come from technologies that existing legal frameworks did not anticipate fully. Cyber operations can damage infrastructure without crossing a physical border. Artificial intelligence can influence military targeting. Autonomous weapons may increasingly make decisions at speeds that reduce human control.

Questions immediately follow. When does a cyberattack amount to the use of force? When can a state respond in self-defence? Who is responsible when an autonomous system causes unlawful harm? How should civilian data infrastructure be protected during conflict? What obligations apply to private technology companies whose platforms become strategically important?

The international system has partial answers but few universally settled solutions.

This is where power increasingly moves from territory toward code, compute and standards. Countries able to shape technical and legal standards around AI, cyber operations, telecommunications and digital infrastructure will influence the behaviour of others without exercising territorial control.

The future of international law will therefore be written partly inside technical standard-setting forums as well as diplomatic conferences.

Climate Change Will Test Traditional Legal Categories

Climate change creates another legal challenge because its effects do not fit neatly inside traditional concepts of sovereignty and responsibility. Rising seas, extreme weather and changing agricultural conditions can displace populations across borders without a conventional armed conflict.

Existing refugee law was not primarily designed for climate displacement. Questions of compensation, historical responsibility, adaptation finance and the legal status of disappearing island states may become increasingly important.

Here again, the political problem will involve inequality. Countries that contributed least to historical emissions may suffer some of the most severe consequences. If international law cannot provide fair mechanisms for dealing with such asymmetry, climate politics may further weaken confidence in the system.

Sanctions Show How Law and Power Increasingly Overlap

Economic sanctions have become another important area where legal and geopolitical authority intersect. Governments increasingly use financial restrictions, asset freezes, export controls and investment barriers instead of military force.

These measures can impose significant costs, but their legality and legitimacy may be contested depending on whether they are authorised multilaterally or imposed unilaterally.

The expansion of sanctions illustrates a broader transformation in power. States can now exert coercion through financial networks, technology access, supply chains and payment infrastructure.

International law therefore has to respond to methods of statecraft that operate below the traditional threshold of war but can still cause significant economic and social damage.

The Counter-View: International Law Works More Than Its Critics Admit

There is a strong realist argument that international law is fundamentally weak because states obey rules only when doing so serves their interests. Major conflicts appear to support this view because powerful governments can violate norms, contest jurisdiction or ignore decisions.

But this interpretation overlooks how extensively international law operates in ordinary international life. Aviation routes, postal systems, maritime navigation, diplomatic relations, trade, telecommunications, extradition, treaties and countless technical agreements function because states broadly follow common rules.

If international law were truly meaningless, international commerce and diplomacy would become dramatically more difficult.

The problem is therefore not universal lawlessness. It is that compliance becomes weakest precisely where political stakes become highest.

That distinction matters because it shows why abandoning the system would be a mistake.

Without International Law, Smaller States Lose the Most

Powerful countries possess military, economic and diplomatic resources that allow them to defend their interests even when institutions fail. Smaller states depend much more heavily on rules.

International law provides weaker countries with a recognised language through which they can challenge aggression, defend maritime rights, demand treaty compliance and mobilise international opinion.

The system does not guarantee victory. But without it, weaker states would have little beyond alliances, deterrence and appeals to political sympathy.

This is why even imperfect law matters. It does not eliminate power politics, but it places boundaries around what governments can openly claim as legitimate.

Reform Must Focus on Consistency as Much as New Rules

The world does not necessarily suffer from a shortage of legal principles. Many fundamental rules already exist. The greater weakness is inconsistent implementation.

Reform should therefore focus on making institutions more representative, improving compliance with court decisions, reducing obvious double standards and strengthening accountability mechanisms that do not depend entirely on geopolitical alignment.

The Security Council’s legitimacy problem is particularly important. A system that claims sovereign equality while granting permanent veto privileges will continue facing questions about institutional fairness.

International courts also need political support. States cannot celebrate legal institutions only when rulings favour them and dismiss them whenever judgments become inconvenient.

A rules-based order requires acceptance that rules occasionally produce outcomes governments dislike.

Three Possible Futures for International Law

In the strongest scenario, states respond to growing instability by strengthening international institutions. Courts gain greater legitimacy, Security Council reform advances gradually, legal standards for AI, cyber operations and autonomous weapons become clearer, and major powers accept greater consistency in applying rules.

A second possibility is continued selective legalism. International law remains important in trade, diplomacy and routine state relations, but high-stakes conflicts continue to expose severe enforcement gaps. Governments invoke law strategically, courts remain influential but constrained and legal legitimacy survives without becoming fully universal.

The weakest scenario would involve deeper fragmentation. Rival geopolitical blocs develop competing legal interpretations, sanctions systems, technology standards and institutions. Major powers increasingly ignore common rules, while smaller states rely on alliances rather than international law for protection. The result would not be the disappearance of law, but the emergence of competing legal orders attached to competing centres of power.

International Law Survives Because the Alternative Is Worse

International law remains caught between aspiration and power. It promises sovereign equality in a system structured by unequal capabilities. It protects human rights while depending heavily on governments for enforcement. It creates courts whose authority ultimately relies on states willing to cooperate with them.

Those contradictions are real, but they do not make international law meaningless.

Law is a shield when weaker states invoke it against aggression. It becomes a sword when governments use legal claims against rivals. It becomes a stage when courts and international institutions shape legitimacy even without the power to compel immediate compliance.

India has strong reasons to defend this system while demanding reform. A more multipolar world without commonly accepted rules would not automatically become fairer. It could simply become a world in which stronger states impose their preferences more openly.

The task is therefore not to replace law with power but to narrow the gap between them.

International law survives not because it always wins. It survives because without it, the weak have little language beyond grievance and the powerful have little restraint beyond the fear of other powerful states.

The future of international order will depend on whether countries can make rules more consistent, institutions more representative and enforcement less dependent on political convenience.

International law remains powerful because the world still needs a language of justice. It remains weak because the world has not yet built an equal system for enforcing it.
