SEOUL — North Korea said on Monday that a recent US–South Korean joint military exercise was a nuclear war rehearsal targeting the country and vowed to accelerate efforts to strengthen its nuclear deterrent, according to state media KCNA, Reuters reported.

Kim Jong-sik, a first vice department director of the ruling Workers' Party, said the Iron Mace exercise showed the United States remained unchanged in its "wild ambition to stifle North Korea with nukes" and that such threats were "escalating with each passing day," KCNA said. In the statement carried by Yonhap, Kim called Iron Mace "the most hideous nuclear war rehearsal aimed at using nuclear weapons against the DPRK."

The United States and South Korea held Iron Mace from September 29 to October 2 at the Joint Chiefs of Staff headquarters in Seoul, according to Seoul's military. The tabletop exercise is aimed at integrating US nuclear capabilities with South Korean conventional forces to deter North Korean threats, and is conducted under the Nuclear Consultative Group framework.

A vow, but no sign yet of follow-through, Seoul says

Kim said Iron Mace and other joint military activities by Washington and Seoul underscored the need for North Korea to bolster its nuclear forces at a faster pace, and that strengthening the deterrent is an "immutable" national defence policy, Yonhap reported. He also said Pyongyang would ensure its nuclear deterrent "defends the sovereignty and security of the state and regional peace in a responsible manner."

Yang Moo-jin, a professor emeritus at the University of North Korean Studies, said Kim Jong-sik's role could be expanding beyond the development and production of missiles to include nuclear and missile policy, Reuters reported. South Korea's military said on Monday, however, that there were no confirmed indications yet that Pyongyang had followed through on the threat.

What happens next: the statement is a warning, not a launch or a test, and Seoul says it has seen no confirmed move behind the words so far. Any actual step — a missile test, a new deployment or a change at North Korea's nuclear sites — would be the development that turns Monday's rhetoric into a new phase of the standoff.
