SEOUL - US President Donald Trump is leveraging an explosion aboard a Korean-operated cargo ship in the Strait of Hormuz to pressure Seoul into joining Washington's "Project Freedom" naval mission, even as Iran's top diplomat warned that the operation amounts to "Project Deadlock," The Korea Times reported on Tuesday.

The pressure campaign intensified Monday after the HMM Namu, one of several Korean vessels stranded in the strait since the outbreak of the U.S.-Israel war against Iran, sustained damage from an explosion and fire at 8:40 p.m. Korea time. No casualties were reported, but the incident has dramatically shifted the calculus in Seoul's long-standing refusal to directly participate in U.S.-led military operations in the vital waterway.

Hours after the incident, Trump took to social media, directly tying the ship's fate to Korea's strategic choices.

"Iran has taken some shots at unrelated Nations with respect to the Ship Movement, PROJECT FREEDOM, including a South Korean Cargo Ship. Perhaps it's time for South Korea to come and join the mission!" Trump wrote, without providing evidence, that Iran attacked the Korean-operated vessel.

The US has not publicly released damage assessment or attribution data. Iran's Revolutionary Guards have denied any involvement, and on Monday reiterated that no commercial ships had been "illegally interdicted" in the strait -- a direct contradiction of earlier U.S. military claims that two US-flagged merchant vessels had transited safely.

Amid the escalating rhetoric, Iranian Foreign Minister Seyed Abbas Araghchi issued a stark warning on social media that appeared calibrated to exploit allied war-weariness.

"Events in Hormuz make clear that there's no military solution to a political crisis," Araghchi posted on X. "As talks are making progress with Pakistan's gracious effort, the U.S. should be wary of being dragged back into a quagmire by ill-wishers. So should the UAE."

He then directly addressed Washington's signature naval doctrine: "Project Freedom is Project Deadlock."

The statement, seen by The Korea Times as a direct message to US allies, including Korea, frames any participation in the mission as an open-ended military commitment without a clear exit strategy.

South Korea's Presidential office has so far resisted US pressure, maintaining that Korea is committed to "practical contributions" to maritime security without joining active combat operations.

"The government holds the principle that safety at international maritime passage and free navigation meets all nations' common interest and should be protected according to international law," the President's Office said in a statement Tuesday.

"We are reviewing the U.S. proposal about the Strait of Hormuz based on the principle, the military readiness posture on the Korean Peninsula and domestic laws. About Project Freedom, Korea and the U.S. have been closely communicating for safe use of key waterways, including the Hormuz Strait."

That review, first reported in March when Trump requested five allies, including Korea, to send military vessels to Hormuz, has yet to produce a decision. Instead, Seoul has participated in multinational discussions led by the UK and France aimed at reopening the strait, and last week the US proposed a new initiative called Maritime Freedom Construct, also aimed at safeguarding the safe passage of ships.

Experts say the HMM Namu incident has given Washington the leverage it lacked for months.

The Strait of Hormuz remains the world's most critical oil chokepoint. For Korea, which relies on the strait for the majority of its crude oil imports, the stakes could not be higher.

But Araghchi's framing, "Project Freedom is Project Deadlock", has found a receptive audience in Seoul's National Assembly, where opposition parties have already signaled they would block any resolution authorizing combat operations.

As one senior presidential office official, speaking on condition of anonymity, told The Korea Times: "We are allies, not subordinates. If Washington wants us to join a 'quagmire,' they need to show us the exit before we enter the door."

For now, the HMM Namu remains under repair. The investigation into the explosion continues. And Korea waits, caught between an impatient president in Washington and a deadly patient foreign minister in Tehran.
