A moral nadir in our waters

The sinking of the IRIS Dena just beyond Sri Lanka’s territorial waters marks a deeply troubling moment for international conduct at sea. If the facts as widely reported hold true, what occurred was not merely a military action but a profound failure of humanity. For a nation that has long presented itself as a defender of international order and the rule of law, the actions by the United States represent a disturbing departure from the very principles it claims to uphold.

IRIS Dena had recently participated in a naval exercise and was unarmed at the time it was struck by torpedoes. Naval exercises routinely involve cadets and trainee officers, and such ships are not configured for combat readiness immediately afterward. The destruction of a vessel carrying large numbers of cadets and non-combat personnel makes the loss of over 150 lives not just tragic but morally indefensible.

Even in times of war, there are rules and obligations. International humanitarian law, painstakingly developed through centuries of conflict, rests on simple principles and chief among them are humanity, distinction, proportionality and military necessity.  All these principles were violated in this incident as a vessel that is unarmed, not engaged in hostilities, and not presenting an imminent danger was targeted with lethal force.

For Sri Lanka, the issue goes beyond geopolitics. Our waters must be a place of refuge. Ships in distress, regardless of nationality, must be received under maritime tradition and humanitarian norms. Those norms now appear to be under pressure as reports suggest that the United States embassy in Colombo has urged our Government not to repatriate survivors from the destroyed vessel, or from another vessel that sought refuge after mechanical failure. These are simply alarming developments and a tragic reminder of the depths to which the US has sunk in its latest incarnation under the Trump administration .

The broader consequences are equally significant. For decades, the United States cultivated goodwill across the Indian Ocean region through diplomacy, development partnerships, and the projection of democratic ideals. That soft power depended not merely on economic influence or military projection but on the perception that American leadership carried a moral dimension.

Incidents such as this risk eroding that perception rapidly. Trust, once lost, is rarely regained easily. In the eyes of many across South Asia and beyond, the sinking of an unarmed vessel with such catastrophic loss of life will be remembered less as a tactical event and more as a symbol of moral decline.

The United States has justified its broader military posture against Iran as part of a campaign to reshape political realities in the region and deliver on a regime change in Teheran. Yet history often delivers ironic verdicts. The regime that appears most challenged by these actions may not be in Tehran but in Washington itself where strategic calculation seems increasingly divorced from ethical restraint.

When the dust settles on this dark chapter in the history of US involvement in West Asia, historians will likely ask how a nation that once championed humanitarian principles, stood mostly on the right side of history, allowed itself to drift so far from them.

For Sri Lanka, our commitment must remain to humanitarian law, maritime tradition, and the sanctity of human life. No matter the pressures of great-power politics, these principles must remain non-negotiable. Despite the sinking of the Iranian ship, we must not allow moral credibility to drown with it.
