[Editorial] Hormuz dilemma

A maritime bottleneck carrying most of South Korea’s energy imports is a perilous arena for symbolic alliance gestures. Yet Seoul faces mounting pressure to deploy forces to the Strait of Hormuz, where deepening conflict threatens vital commercial shipping.

The presidential office said Friday that no decision had been made and that various options remained under review. Any contribution, it said, would have to preserve the nation’s defense readiness on the Korean Peninsula and comply with domestic law.

Those are sensible guardrails. They should remain the starting point, not boxes to be checked before a decision has already been made.

The strategic dilemma is real. About 70 percent of Korea’s crude oil imports pass through the strait, making freedom of navigation directly relevant to its economic security.

The country also has a legitimate interest in helping keep an international sea lane open. It cannot reasonably expect others to protect routes on which its energy-dependent economy relies.

The question is how to contribute without making Korean personnel part of a widening war.

The alliance, meanwhile, cannot be ignored. US President Donald Trump has repeatedly complained that Korea has declined to make a sufficient contribution to the effort around Iran.

Washington has been pressing Seoul across security, trade and investment issues, while talks between the allies have encountered renewed difficulties. The temptation to treat the Strait of Hormuz as merely another bargaining chip is understandable, if shortsighted.

That would be a costly way to manage an alliance.

A military alliance should not become an accounting ledger in which a contribution to one conflict is exchanged for concessions elsewhere. Decisions involving Korean service members and the use of military force require their own standards.

Linking a deployment to semiconductor negotiations, tariffs or other bilateral disputes would weaken the nation’s position precisely when its leaders need room for independent judgment.

Nor should the label “noncombat” create a false sense of security. A maritime patrol aircraft gathering information or a support vessel supplying military forces may have a defensive purpose, yet such assets operate within the machinery of war.

In an active conflict zone, they can become targets regardless of their formal mission. A single attack could expose Korea to retaliation and create pressure for a deeper military response.

The constitutional issue is equally important. Article 60 requires National Assembly consent for the overseas deployment of the armed forces. The requirement is not a procedural nuisance. It exists because sending military personnel abroad carries consequences that cannot be reversed as easily as a diplomatic statement.

If Seoul proceeds, the mission, command structure, rules of engagement, duration and conditions for withdrawal should be clearly defined before lawmakers are asked to approve it.

There is also Tehran. Korea has maintained pragmatic relations with Iran for decades, and worsening those ties could complicate the very energy security that a Hormuz deployment is meant to protect.

Military involvement carries a paradox: An effort to secure shipping could expose Korean vessels and Koreans themselves to greater danger.

There are alternatives. Japan’s case illustrates that an ally can contribute to maritime security while maintaining legal and operational boundaries. Seoul could work with European partners on freedom of navigation while restricting any military involvement to strictly defensive or postconflict roles, such as mine clearance and humanitarian assistance.

The choice is not between satisfying Washington and jeopardizing the alliance; it is between contributing on terms the country can defend and accepting a deployment whose logic could widen as the war escalates.

The government must state its legal constraints and defense priorities clearly to Washington. Hormuz calls for a contribution grounded in national interests, not a loyalty test measured by how far Seoul is willing to follow Washington into danger.
