Seoul, South Korea – US and South Korean estimates of North Korea’s nuclear arsenal vary as Pyongyang continues to develop its nuclear program and enhance its missile capabilities. Meanwhile, concerns are growing about the expanding scope of its threats in the region. US President Donald Trump has stated that North Korea possesses approximately 57 nuclear weapons. South Korean estimates, however, suggest a much larger number, indicating that Pyongyang’s arsenal could range between 80 and 120 nuclear warheads.
South Korea’s defense minister emphasized that determining the actual number of North Korea’s nuclear weapons remains extremely difficult due to the secretive nature of Pyongyang’s nuclear program. There is no way to directly verify the size of the arsenal. This discrepancy reflects the difficulty in obtaining accurate data on North Korea’s nuclear capabilities, which rely on secrecy in developing its facilities and producing fissile material. Meanwhile, North Korea continues to work on developing missiles capable of carrying nuclear warheads.
Pyongyang considers its nuclear program a fundamental part of its defense system and refuses to abandon it despite international pressure and sanctions. It maintains that possessing nuclear deterrent capabilities guarantees the regime’s security against the United States and its allies. The debate surrounding the size of North Korea’s arsenal comes at a time of rapidly evolving political and military relations between Washington, Seoul, and Pyongyang. Simultaneously, there is talk in the US about the possibility of resuming contact with North Korean leader Kim Jong-un.
South Korea fears that the continued development of North Korea’s nuclear and missile programs will shift the balance of deterrence on the Korean Peninsula, especially as Pyongyang develops more advanced missiles with longer ranges. Observers believe that the discrepancies in estimates are not merely about numbers, but also reveal the magnitude of the challenge facing US and South Korean intelligence agencies. This becomes evident when attempting to determine North Korea’s true capabilities and whether its current arsenal is approaching the upper limit of current estimates.
