US cancels Ssangyong exercise with South Korea over Iran war troop constraints

Cancellation of the Ssangyong exercise

The United States military has canceled the biennial Ssangyong joint amphibious landing exercise scheduled for September 2026 alongside South Korean forces. South Korean Marine Corps spokesman Han Seung-jeon announced the decision at a press briefing in Seoul on Monday, attributing the cancellation to reduced US troop availability caused by the war in Iran. The US Marine Corps had formally notified South Korean counterparts in June that its deployment capabilities for the division-level maneuver would be restricted by military commitments in the Middle East. Ssangyong, which translates to Twin Dragons, represents a core bilateral maneuver that typically mobilizes approximately 10,000 marine troops alongside warships, aircraft, and armored amphibious vehicles to practice transitions from sea to land. Defense officials in Seoul noted that both allied governments are discussing whether the joint landing operations can be rescheduled, while United States Forces Korea did not release an immediate statement.

The US Marine Corps officially informed us in June that its ability to deploy forces for this year's Ssangyong exercise would be limited due to the situation in the Middle East.

Curtailment of Ulchi Freedom Shield

The decision to call off the landing maneuvers follows a separate reduction of the annual Ulchi Freedom Shield joint exercise ordered by US President Donald Trump. Those drills, designed to rehearse territorial defense against a North Korean assault, were cut from an 11-day program to five days, concluding on Friday, 21 August, rather than running through the scheduled end date of 27 August. Following Trump's intervention, allied commanders scrapped the planned counter-offensive phase of the exercise. Trump posted on Truth Social that the joint operations were expensive and criticized the government in Seoul for refusing to join US military operations against Iran. Trump also described the allied maneuvers as inappropriate and hostile toward North Korea.

Strategic shifts and diplomatic aims

Trump connected the cutbacks in joint training to an intention to resume direct negotiations with North Korean leader Kim Jong Un. Trump held three meetings with Kim during his first term in office and stated last week that cooperation with the North Korean leadership remained important. In his public comments, Trump asserted that North Korea possesses 57 powerful nuclear weapons. Government estimates produced in Seoul present a higher figure, placing the North Korean arsenal at between 80 and 120 nuclear warheads. Unnamed US government officials cited in media reports indicated that the reductions to joint drills were intended to establish diplomatic openings for future high-level talks.

North Korean weapons tests and reactions

Despite the early termination of the Ulchi Freedom Shield exercise and diplomatic overtures from Washington, authorities in Pyongyang issued statements mocking the curtailed allied maneuvers. North Korea also conducted weapons tests during the previous week, launching 10 short-range ballistic missiles while condemning the allied drills. The North Korean government has consistently denounced combined US and South Korean military exercises as rehearsals for an invasion of its territory. The consecutive reductions to scheduled military drills take place as bilateral relations between Washington and Seoul face friction over Middle Eastern military commitments and defense cooperation parameters.
