Growing threat from North Korea, Ukraine war makes some South Koreans rethink nuclear-free policy

By Kang Seung-woo

South Korea is facing growing calls to acquire nuclear weapons irrespective of ideological dogma. Such calls are being fueled by North Korea's growing nuclear menace and misgivings about the U.S.' extended deterrence if Pyongyang decides to attack its southern neighbor.

"There has been a nuclear taboo ― a normative inhibition against the first use of nuclear weapons ― but Russia is about to break it in its war against Ukraine, thereby stoking concerns among countries, (including South Korea) that do not have their own nuclear weapons," said Go Myong-hyun, a senior fellow of the Asan Institute for Policy Studies.

Go added that, despite Russia's threat to use nuclear weapons against Ukraine, the United States and NATO were poised to respond to it with conventional weapons, with many South Koreans fearful of Washington's possible half-hearted response to North Korea's potential nuclear attack against the South.

Cheong Seong-chang, the director of the Center for North Korean Studies at the Sejong Institute, also said that the growing interest in the development of a domestic nuclear weapons program comes as the U.S.' steadfast nuclear retaliation, in the case of North Korea using nuclear weapons against South Korea, appears uncertain.

"Even though the allies held an Extended Deterrence Strategy and Consultation Group (EDSCG) meeting in September, for the first time in nearly five years, they failed to reach an agreement on the U.S.' immediate and automatic retaliation in response to a North Korean nuclear attack against the South," Cheong said.

The EDSCG, a high-level consultative mechanism to achieve North Korean denuclearization through steadfast deterrence, was held in Washington, D.C., on Sept. 16, but its joint statement merely stipulated that North Korea would face an "overwhelming and decisive" response in the event of a nuclear attack.

"North Korea has made significant progress in the development of an intercontinental ballistic missile capable of reaching the U.S. mainland, so it seems that our trust in the U.S. nuclear umbrella, aimed at ensuring deterrence against nuclear threats, has been eroded," Cheong said.

According to a recent poll by the Institute for Peace and Unification Studies at Seoul National University, more than half of South Koreans, or 55.5 percent, supported the development of a domestic nuclear weapons program, with 92.5 percent of 1,200 respondents believing that North Korea will not abandon its nuclear program.

In that respect, calls for an independent nuclear arsenal have been reignited amid an accelerated buildup of North Korea's nuclear weapons.

"Ukraine was the world's third-largest nuclear power, but it disarmed its nuclear weapons following security assurances from the U.S., Britain and Russia and as a result, Ukraine is now facing Russia's nuclear attack," Daegu Mayor Hong Joon-pyo said on Facebook, Wednesday,
