President Lee Jae‑myung said South Korea cannot acquire nuclear weapons because the country would be unable to withstand the resulting international sanctions [1].
This position clarifies the administration's stance on national security at a time when the debate over nuclear deterrence remains a point of contention both domestically and globally. By ruling out nuclear armament, the president is prioritizing economic stability and international diplomatic standing over the pursuit of an independent nuclear deterrent.
Lee said the topic of denuclearization has garnered significant attention recently [2]. He said the economic and political costs of defying global non-proliferation norms would be too high for the nation to bear [1].
"South Korea cannot arm itself with nuclear weapons... we cannot endure international sanctions," Lee said [1].
The president said he felt it was appropriate to speak on the matter because denuclearization is a subject of high interest not only within the country but also internationally [2]. His comments suggest a commitment to existing security frameworks and a reliance on diplomatic channels to manage regional threats.
While some political factions have previously suggested that South Korea should develop its own nuclear capabilities to counter regional adversaries, Lee's statement serves as a definitive rejection of that path. He said the risk of isolation and the collapse of trade networks under sanctions would outweigh any perceived security gains [1].
“"South Korea cannot arm itself with nuclear weapons... we cannot endure international sanctions,"”
This declaration reinforces South Korea's adherence to the Nuclear Non-Proliferation Treaty (NPT) and signals to the international community, particularly the U.S. and China, that the administration will not unilaterally shift its security posture. By highlighting the fragility of the economy against sanctions, Lee is framing the nuclear issue as an economic survival matter rather than just a military strategy.
