North Korea has unveiled footage of a carbon-fiber solid-fuel engine test for an intercontinental ballistic missile (ICBM), with Chairman Kim Jong-un observing. This should be seen as an open declaration of intent to develop multiple independently targetable reentry vehicle (MIRV) ICBMs capable of simultaneously striking multiple targets across the U.S. mainland. The solid-fuel engine test carries an increasingly pronounced external message: "North Korea is not Iran." Having watched the U.S. arrest Venezuela's president and launch a surprise attack on Iran, North Korea has firmly demonstrated its resolve to forcefully counter any possibility of U.S. military intervention on the Korean Peninsula.
North Korea's intensified threats against the United States are closely tied to its "tongmibongnam" strategy — bypassing South Korea to negotiate directly with Washington. The intent is to drive a wedge in the South Korea-U.S. alliance. Analysts also suggest that following the war with Iran, North Korea is now more likely to reject U.S. demands for nuclear dismantlement. Against this backdrop, President Lee Jae-myung's remark on the 27th that "excessive dependence [on the South Korea-U.S. alliance] must be avoided" has sparked controversy. The opposition criticized him for "undermining the value of the alliance by framing it in terms of dependence."
President Lee's remark was prefaced by the statement that "an ironclad South Korea-U.S. alliance is indeed an essential element for peace and stability on the Korean Peninsula." Nevertheless, it inadvertently raised misunderstandings about whether he was belittling the alliance's value. Coming amid the Donald Trump administration's push for "alliance modernization" — including the redeployment of THAAD systems to the Middle East — the remark risks being distorted and spread as an unintended message. Separately, President Lee's comment to the families of the Cheonan victims — "Do you think North Korea would apologize just because we ask them to?" — also drew heated debate. The Presidential Office explained it was "an expression of regret over the harsh reality of inter-Korean relations," but the remark is difficult to defend against criticism that it failed to consider the families' grief.
The words of a president, who serves as commander-in-chief of the armed forces, can be read as policy signals. Security issues such as inter-Korean relations and the South Korea-U.S. alliance are particularly sensitive. One must always be mindful that a specific message can be distorted or generate diplomatic and security repercussions contrary to its intent. How U.S.-North Korea relations will unfold remains uncertain, but what is clear is that North Korea is currently placing greater weight on confrontation than dialogue. We must not forget that Korean Peninsula security must be built on a firm South Korea-U.S. alliance.
