South Korea, US discussing exercises using nuclear assets, says Yoon

---

SEOUL: South Korea and the United States are discussing possible joint exercises using US nuclear assets, South Korean President Yoon Suk-yeol said, after North Korean leader Kim Jong Un labelled the South as its “undoubted enemy” in flaring cross-border tensions.

Yoon’s comments come days after he called for a “war preparation” with an “overwhelming” capability, following a year marked by the North’s record number of missile tests, and the intrusion of North Korean drones into the South last week.

“The nuclear weapons belong to the United States, but planning, information sharing, exercises and training should be jointly conducted by South Korea and the United States,” Yoon said in an interview with the Chosun Ilbo newspaper published on Monday.

The newspaper quoted Yoon as saying the joint planning and exercises would be aimed at a more effective implementation of the US “extended deterrence,” and that Washington was also “quite positive” about the idea.

The term “extended deterrence” means the ability of the US military, particularly its nuclear forces, to deter attacks on US allies.

A Pentagon spokesperson said: “We have nothing to announce today,” when asked about Yoon’s comments, adding that the alliance remains “rock-solid.”

Yoon’s remarks also come a day after North Korean state media reported that its leader Kim called for developing new intercontinental ballistic missiles (ICBMs) and an “exponential increase” of the country’s nuclear arsenal.

At a meeting of the ruling Workers’ Party meeting last week, Kim said South Korea has now become the North’s “undoubted enemy” and rolled out new military goals, hinting at another year of intensive weapons tests and tension.

Inter-Korean ties have long been testy but have been even more frayed since Yoon took office in May, promising a tougher stance on the North rival.

On Sunday, North Korea fired a short-range ballistic missile off its east coast, in a rare late-night, New Year’s Day weapons test, following three ballistic missiles launched on Saturday.

The North’s official KCNA news agency said the projectiles were fired from its super-large multiple rocket launcher system, which Kim said “has South Korea as a whole within the range of strike and is capable of carrying tactical nuclear warheads.”

The North’s race to advance its nuclear and missile programmes has renewed debate over South Korea’s own nuclear armaments, but Yoon said in the Chosun Ilbo interview that maintaining the Treaty on the Non-Proliferation of Nuclear Weapons remained important.

Yoon’s comments on the nuclear exercises are the latest demonstration of his tough stance on North Korea.

He has said South Korea must punish and retaliate against any provocation by North Korea, calling it the most powerful means to deter any further provocations.

“This year could be a year of crisis with military tension on the Korean peninsula going beyond what it was like in 2017,” said Hong Min, a senior researcher at the Korea Institute for National Unification, referring to the days of the “fire and fury” under the Trump administration.

“North Korea’s hardline stance…and aggressive weapons development when met with South Korea-US joint exercises and proportional response could raise the tension in a flash, and we cannot rule out what’s similar to a regional conflict when the two sides have a misunderstanding of the situation,” Hong said.
