South Korea, U.S. to hold simulated drill on North Korea’s use of nuclear weapons

The one-day computer simulation comes as the two countries push to strengthen their 70-year alliance in the face of North Korea’s increasingly aggressive nuclear doctrine.

South Korean and United States militaries will hold a tabletop exercise at the Pentagon next week to hone their joint response to a potential use of nuclear weapons by North Korea, Seoul officials said on February 17.

The one-day computer simulation set for Wednesday comes as the two countries push to strengthen their 70-year alliance in the face of North Korea’s increasingly aggressive nuclear doctrine.

The exercise is meant to focus on measures against North Korean nuclear threats and discuss how to boost a U.S. extended deterrence — America's ability to use its full capabilities, including nuclear, to deter attacks on its allies, South Korea’s Defence Ministry said in a statement.

It said the exercise would set up possible scenarios where North Korea uses nuclear weapons, explore how to cope with them militarily and formulate crisis management plans.

Worries about North Korea’s nuclear programme deepened in South Korea after the North conducted a record number of missile tests in 2022 and adopted a law that authorises the preemptive use of nuclear weapons. Many of the missiles tested were nuclear-capable weapons that place South Korea within striking distance.

In response to the intensifying North Korean threats, South Korea and U.S. militaries have expanded their joint drills and stepped up pressure on the North to abandon its nuclear programme. In January, Defence Secretary Lloyd Austin said that the U.S. would also increase its deployment of advanced weapons such as fighter jets and bombers to the Korean Peninsula.

During their annual meeting in November, Mr. Austin and South Korean Defence Minister Lee Jong-Sup also agreed to conduct tabletop exercises annually and further strengthen the alliance’s information sharing, joint planning and execution. Mr. Austin reiterated a warning that any nuclear attack against the U.S. or its allies would result in the end of North Korean leader Kim Jong Un's regime.
