Experts urge South Korea to hold Iran accountable over HMM ship attack

May 29 (Asia Today) -- South Korean defense experts said the government should take a tougher position toward Iran after investigators concluded that an Iranian-developed anti-ship missile was likely used in an attack on the HMM Namu.

Experts said Thursday that Seoul needs a firm diplomatic response to the results of the government investigation into the unidentified aerial objects that struck the HMM-operated vessel.

The government said Wednesday that the objects were highly likely to have been Noor-series anti-ship missiles developed by Iran. Technical analysis found the engine resembled an Iranian-made turbojet engine, and some components carried markings believed to be from an Iranian manufacturer.

South Korean officials said the evidence points toward Iran but stopped short of making a final judgment on who carried out the attack or whether it was intentional. The government summoned Saeed Koozechi, Iran's ambassador to South Korea, but Koozechi denied that Iran was involved.

"If it was actually confirmed to be an Iranian missile, it should be viewed as an act by the Iranian government," said Kwon Yong-soo, professor emeritus at Korea National Defense University. "The missile's maximum range is short, and because of the flame at launch, it would have been visible where it came from."

Kwon said the government should be able to explain whether the missile was fired from land, a ship or a fast boat.

"If it was not Iran's act, Iran itself should present evidence," he said.

Yang Uk, a research fellow at the Asan Institute for Policy Studies, said the evidence points to an Iranian-made anti-ship missile.

"Even if Iran denies it, that denial is not persuasive," Yang said. "Anti-ship missiles are weapons that only states, governments and militaries can operate."

Yang said Iran may have provided missiles to an armed group, such as the Houthi rebels, but the distance would have been too far for such a launch.

"If the Islamic Revolutionary Guard Corps fired it and the Iranian government pretends not to know, that would prove Iran's own command and control is inadequate," he said.

Some experts said the South Korean government's response has been too weak, even though it summoned Koozechi immediately after announcing the investigation results.

A Foreign Ministry official said summoning Iran's ambassador was a serious diplomatic measure.

"Summoning the Iranian ambassador to South Korea is by no means meaningless," the official said. "The measure itself shows our firm position."

The official said Seoul had sent investigation teams twice, collected debris, reached its conclusion through analysis by expert agencies, publicly announced the findings and explained them to the other country.

"That itself is a serious diplomatic step," the official said.

Yang said some may argue South Korea does not need to create unnecessary conflict with Iran. But he said Seoul should at least secure something from the Iranian government if it takes that position.

"Given that the evidence points to Iran, we should at least apply pressure to ensure our ships are allowed to return safely," Yang said. "If we do not even do that, then we are refusing to do what a state should do."
