National defence is not a classroom lesson

In recent times, Sri Lanka has witnessed a rather curious spectacle in its public discourse. A subject as grave and consequential as national defence has found its way into the realm of political banter and casual ridicule. Statements made during election campaigns, and later echoed in parliamentary exchanges, have sometimes treated defence policy as though it were a matter that could be explained with the simplicity of a classroom demonstration. While such remarks may generate momentary laughter in political gatherings, they raise a deeper concern: whether the country is paying sufficient attention to the complex realities surrounding national defence in an increasingly uncertain world.

Behind the humour and rhetorical exchanges, however, lies a more serious question. In a world where security challenges have grown increasingly complex and interconnected, national defence can no longer be approached through simplistic explanations or political improvisation. It requires a deeper understanding of strategic realities, institutional responsibility, and the international frameworks within which sovereign states must operate.

Public debate is a vital feature of democracy. Yet the quality of that debate must correspond with the seriousness of the subject under discussion. National defence concerns the sovereignty of the state, the safety of its citizens, and the stability of its institutions. When such matters are reduced to rhetorical contest or political humour, the nation risks overlooking the depth and complexity of the responsibilities involved.

Even if those participating in such discussions are not military professionals or veterans, it is reasonable to expect that a topic of such significance would at least be approached by individuals who have taken the trouble to acquaint themselves with the broader principles and contemporary thinking surrounding national defence.

The broader meaning of national defence

In modern strategic thinking, national defence has evolved far beyond the traditional understanding of armed forces defending the country against external invasion. Today it is widely recognised as a comprehensive national effort, often described as “Total Defence” or “Comprehensive Defence.”

Under this broader concept, defence is not limited to the military alone. It encompasses the combined efforts of Government institutions, economic systems, technological infrastructure, civil organisations, and the citizenry itself. Military capability remains an essential pillar, but it operates within a wider framework designed to protect the nation against a variety of threats, both conventional and unconventional.

Modern security challenges are often hybrid in nature. Cyber attacks, economic coercion, disinformation campaigns, terrorism, pandemics, and disruptions to critical infrastructure can weaken a nation as effectively as traditional warfare. Consequently, national defence today must integrate military preparedness with intelligence capability, economic resilience, cyber security, and the safeguarding of essential services.

A country’s strength in times of crisis therefore depends not only on its armed forces but also on the resilience of its institutions and the unity of its society.

 Sri Lanka’s strategic environment

For Sri Lanka, the need for a thoughtful and informed approach to national defence is particularly important. The country occupies a strategically sensitive position in the Indian Ocean, lying just a few nautical miles from the main East–West international maritime shipping lane, one of the busiest sea routes in the world through which a significant portion of global trade and energy supplies pass.

This geographical reality places Sri Lanka within the wider dynamics of regional and global power interactions. The Indian Ocean has increasingly become a theatre where the strategic interests of major powers intersect, and developments occurring far beyond our shores can quickly influence the environment surrounding our island.

Incidents involving naval confrontations between powerful nations in the wider region serve as reminders of how rapidly geopolitical tensions can extend into waters near Sri Lanka. For smaller states situated within such strategic corridors, prudence and careful judgement in matters of defence policy are indispensable.

The discipline of international law

Another critical dimension of national defence lies in the framework of international law within which sovereign States operate. Maritime conventions, diplomatic practice, and the principles governing neutrality and territorial integrity provide the rules that help maintain order and predictability in international relations.

For countries like Sri Lanka, adherence to these principles is not merely a legal formality; it is an essential component of national defence itself. Consistency in following internationally recognised norms strengthens a country’s credibility and protects it from becoming unnecessarily entangled in the rivalries of larger powers.

Handling sensitive situations strictly within the framework of international law demonstrates that the state acts according to established principles rather than according to the personal whims or improvisations of individuals holding office at a particular moment.

 Lessons from other nations

Several small but strategically exposed nations have long recognised the importance of approaching national defence in a comprehensive and disciplined manner. Singapore offers a notable example. Under the leadership of Lee Kuan Yew, the country developed what became known as the “Total Defence” doctrine, integrating military preparedness with civil defence, economic resilience, social cohesion, and psychological readiness.

Singapore’s leadership understood that the security of a small state cannot depend solely on military capability. National strength must be built through the combined resilience of institutions, economic stability, technological capacity, and the unity of its citizens.

An incident during the 1990s demonstrated the seriousness with which Singapore safeguarded its sovereignty and legal principles. When an American citizen, Michael Fay, was convicted under Singapore’s vandalism laws, the case attracted strong diplomatic intervention from the United States, including an appeal from then President Bill Clinton. While Singapore later reduced the severity of the punishment as a gesture of goodwill, it maintained firmly that its laws and judicial processes could not be disregarded under external pressure.

The episode illustrated how even a relatively small nation can command international respect when its decisions are guided by law, institutional discipline, and principled leadership.

Elevating the national conversation

National defence cannot be reduced to slogans, theatrical exchanges, or improvised explanations offered in moments of political enthusiasm. It is a discipline that demands knowledge, strategic foresight, and respect for both national institutions and international obligations.

For a country situated at a sensitive maritime crossroads such as Sri Lanka, the margin for error in matters of defence policy is particularly narrow. Decisions must be guided by informed judgement, adherence to international law, and a clear understanding of the responsibilities that accompany sovereignty.

If the national conversation on defence can rise above momentary humour and partisan rhetoric, it may yet contribute to building the strategic maturity that Sri Lanka will require in the challenging years ahead. Ultimately, the security of the nation will depend not only on the professionalism of its armed forces but also on the wisdom, restraint, and foresight with which its leaders handle the complex realities of the modern world.
