In brief
North Korea condemned the South Korean–U.S. joint drill “Iron Mace” as a hideous nuclear rehearsal, accusing it of threatening DPRK sovereignty. The regime declared that it would accelerate the development of its nuclear deterrent in response. It also referenced other exercises it deems provocatory, while reiterating that “strength” guarantees peace, and it left open the impact of these declarations on the peninsula’s security dynamics.
North Korea denounced the recent South Korean–United States joint military drill, “Iron Mace,” in a statement released on Monday, saying it would accelerate the development of its nuclear arsenal in response to what it called a hideous nuclear rehearsal.
The drill, held from September 29 to October 2 at the Joint Chiefs of Staff headquarters in Seoul, combined South Korea’s conventional forces with United States nuclear capabilities. The exercise was aimed at deterring North Korean threats, according to both participating sides.
In a statement carried by the Korean Central News Agency (KCNA), Kim Jong‑sik, first vice department director of the Workers’ Party of Korea’s Central Committee, described the exercise as “the most hideous nuclear war rehearsal aimed at using nuclear weapons against the DPRK.” He alleged that the exercise merely exposed how the North must continuously strengthen its nuclear forces to counter such threats.
Kim Jong‑sik said:
"The most hideous nuclear war rehearsal aimed at using nuclear weapons against the DPRK."
He went on to say that North Korea would keep enhancing its deterrent at an ever faster pace, calling it an “immutable” national defense policy. The statement emphasized that the regime would ensure its nuclear deterrent “defends the sovereignty and security of the state and regional peace in a responsible manner.”
Kim also denounced other allied drills, including the Hoguk and Freedom Flag exercises with the United States, and the Keen Sword exercise with the United States and Japan. He argued that “the enemies have intensified its military moves in public or behind closed doors.”
The regime accused the joint exercises of accelerating the threat of conventional and nuclear forces in the region, stating that “strength is peace” and that peace can only be guaranteed by strength.
In the statement, Kim added:
"The reality teaches once again the underlying truth that strength is peace and peace is guaranteed only by strength."
Pyongyang’s announcement follows the United States and South Korea’s increasing frequency of joint exercises, which include annual tabletop drills and large‑scale ground exercises, aimed at deterring North Korean aggression and reinforcing alliance cohesion.
There is no indication yet of how the United States or South Korea will respond to the North’s latest remarks; no official comment has been issued by the involved governments.
While the North Korean declaration highlights its intent to strengthen its nuclear deterrent, it remains unclear how the regime’s doctrine of “immutable” deterrence will shift its nuclear posture or how the United States and South Korea might adjust their military cooperation in light of the criticism. The future of the peninsula’s security dynamics remains uncertain, as North Korea’s assertion of nuclear advancement and the allied response to its rhetoric have yet to reach a decoupled outcome.
