South Korea, the United States and Japan launched the 2026 Freedom Edge exercise Monday in international waters east and south of Jeju, running through Friday. On the same day, North Korea announced the commissioning of the destroyer Ganggeon-ho and declared the "nuclear arming" of its navy, while Washington renewed pressure on Seoul to contribute to security operations in the Strait of Hormuz.

South Korea's Joint Chiefs of Staff said the exercise is "an annual, defensive training conducted in compliance with international law and norms, aimed at enhancing deterrence and response capabilities against North Korea's nuclear and missile threats and safeguarding peace and stability in the region." The three countries plan to strengthen operational and joint-response capabilities across maritime, air and cyber domains.

North Korea's Rodong Sinmun reported that Kim Jong-un attended the commissioning ceremony for the new destroyer Ganggeon-ho, where he declared that "the nuclear arming of our navy has been realized" and warned that "our national security is under serious threat from the enemy's open military hostile acts. We must respond thoroughly to such threats with highly professional and overwhelming force, and with the will and full capability to use it."

The commissioning raises the possibility of a retaliatory provocation, such as a ballistic missile launch. North Korea fired more than 10 short-range ballistic missiles into the East Sea on Aug. 20 — one day before the conclusion of the Ulchi Freedom Shield exercise — even after US President Donald Trump had significantly scaled back that exercise's schedule.

Meanwhile, the South Korean government finds itself in a dilemma over a potential deployment to the Strait of Hormuz, as both the US and Iran have been sending competing messages to Seoul. Washington has signaled it is willing to wait for South Korea's contribution, while Tehran has warned it would regard any such deployment as participation in a war against Iran, deepening Seoul's deliberations.

Yu Ji-hun, a research fellow at KIDA, said the situation "requires a sophisticated diplomatic strategy — one that demonstrates to the US Seoul's willingness to contribute as an ally, while persuading Iran that South Korea's military contribution does not constitute participation in a war against it."

Yu added that "rather than being pulled along by the demands of either the US or Iran, it is important to anchor the core rationale for any deployment in South Korea's clear national interests — energy security and the protection of maritime shipping lanes."
