South Korea: Support for Nukes Is on the Rise

Announced on January 30, the latest study on attitudes towards a domestic nuclear deterrent was conducted by the Chey Institute for Advanced Studies, with 60.7% of the respondents to the think tank’s questionnaire saying they believe South Korea is “somewhat in need” of developing its own nuclear weapons. An additional 15.9% said a nuclear deterrent is “very much in need.”

A mere 3.1% of those polled said the South has absolutely no need for its own nuclear weapons, while a further 20.3% responded that there is “little need” for a domestic nuclear deterrent. 

“I believe that we are in a situation in which China is emerging and becoming a huge threat and the US is trying to compete with South Korea,” said Hyobin Lee, an adjunct professor of politics at Chungnam National University.  

“The fact that the US does not subsidize Korean electric vehicles and tries to compete in the semiconductors industry is creating anxiety for South Korea,” she told DW.

Trust in the Nuclear Umbrella  
“South Koreans do not trust the nuclear umbrella provided by the US,” she added. “How can we trust someone for protection if they treat us as a competitor?”

Nevertheless, there is a fear that China’s increasingly aggressive moves in the Indo-Pacific will ultimately lead to conflict.   

“Antipathy towards China is increasing day by day,” Lee said. “According to one survey, about 80% of Koreans say they have antipathy toward China, which is the highest rate in history. Many Koreans believe that there is a relatively high possibility that China and North Korea could attack South Korea.”

The Chey Institute study comes on the heels of a series of similar polls that all point in a similar direction — increasing support for a domestic nuclear capability. In recent years, research by the Chicago Council on Global Affairs put the figure at 71% of the public, while another study by the Asian Institute for Policy Studies determined the support rate to be 70.2%.

Karl Friedhoff, an author of the Chicago Council report, pointed out that the support rate for nuclear weapons is higher in the latest study, although he noted that the methodology employed differed from earlier polls.

His own study emphasized that the acquisition of nuclear weapons was “once a topic for the political fringe” but has now become a mainstream element of security discussions.   

The report added that support for nuclear weapons was “robust,” with far greater support for domestic control over an atomic arsenal than for Washington deploying its own weapons in South Korea to act as a deterrent.

Some 67% of the Korean public favor an independent nuclear capability, against just 9% who want the US to base its weapons in the South.   

Friedhoff also suggested yet another reason for that solid support, a concept called “unwanted use theory.”  

According to the theory, as the credibility of US power and preparedness to use nuclear weapons from bases in South Korea increases, that paradoxically makes the South more of a target for its regional rivals, either as a pre-emptive strike or in retaliation.  

Debate over the South’s nuclear ambitions has been stoked once more by an apparently offhand comment by President Yoon Suk-yeol about the nation’s defense options. In January, he said his nation might need to acquire a nuclear capability or, at the very least, play a more active role in managing US weapons that could be reintroduced to the South.  

Official Opposition 
“The present position of the government is opposed to a domestic nuclear weapons program in South Korea,” Friedhoff said. “However, they do seem to be seeking a return of tactical nuclear weapons or nuclear sharing.”  

Fearful of proliferation and a strong, united response from China and North Korea, the US is opposed to both options. Yet, if South Korea were to try to create its own nuclear deterrent, Friedhoff estimates it would take less than one year to develop a weapon.   

“I think it is important to note that even if South Korea develops nuclear weapons, where is it going to put them?” Friedhoff said. “The land mass is restricted and any nuclear installations would be near a population center. That will draw more protests. Thus, it seems likely that any South Korean weapons program would have to be naval based.”

Any plans for an independent nuclear capability would inevitably be condemned by South Korea’s regional rivals, primarily North Korea and China, as a deliberate effort to destabilize the region and would likely trigger retaliatory economic sanctions from Beijing.  

Japan would be likely to express its concerns, while the US can be expected to resist efforts by the South to develop and deploy atomic weapons on the grounds that it opposes nuclear proliferation.

Any such decision would also mean Seoul would be abandoning its commitments under the Nuclear Non-Proliferation Treaty, with implications for its civilian nuclear energy program.  

Equally, while they are significantly outnumbered, the analysts say, the 24% of the Korean public opposed to nuclear weapons have not yet begun to speak out.   

“The Korean people are not in a situation where they can easily and quickly possess their own nuclear weapons, even if they want to,” said Lee. “South Korea should respect the Nuclear Non-Proliferation Treaty and it will not be easy to break this promise it has signed.”
