South Korea estimates North Korea has 80 to 120 nuclear warheads, far above Trump's figure of 57; defense minister cites private research, can't officially confirm

South Korea's defense minister estimates North Korea possesses 80 to 120 nuclear warheads, significantly higher than President Trump's claim of 57. Ahn Gyu-back cited private research for the assessment but noted he cannot officially confirm the figures due to South Korea's policy on denuclearization.

CuriousCats Full Story

South Korea's defense minister Ahn Gyu-back revealed on Thursday that North Korea may have between 80 and 120 nuclear warheads, a figure that starkly contrasts with President Donald Trump's recent estimate of 57. Ahn stated that this assessment is based on private research, emphasizing the difficulty in determining an exact number due to South Korea's policy of not officially recognizing North Korea as a nuclear-armed state.12

Ahn explained, "We usually see it as around 80 to 120, but it is considerably limited to state an exact number," during a parliamentary committee meeting. He also noted that South Korea's military cannot confirm these estimates officially, adhering to its long-standing denuclearization policy.

Trump's figure of 57 was the first specific number he publicly cited regarding North Korea's arsenal, made during a discussion about his relationship with Kim Jong Un. Ahn declined to comment on Trump's estimate, stating, "the numbers appear somewhat different".

Despite the differing assessments, Ahn reiterated South Korea's reliance on the U.S. nuclear umbrella and maintained that the country cannot develop its own nuclear weapons. He stated, "We cannot develop nuclear weapons. Nor should we accept the deployment of US tactical nuclear weapons," reinforcing South Korea's commitment to its non-nuclear policy.

The South Korean government has traditionally refrained from disclosing detailed estimates of North Korea's nuclear capabilities, reflecting its cautious approach to the ongoing tensions on the Korean Peninsula.

Key Insight
“Ahn Gyu-back said the estimate comes from private research organizations and that Seoul cannot officially confirm the numbers because it does not recognize North Korea as a nuclear state. He also reaffirmed Seoul's reliance on the US nuclear umbrella, ruling out developing its own weapons or hosting US tactical nukes.”
