CWMDC Convenes Amid Trump’s Warning of ‘57 North Korean Nuclear Weapons’; ‘Biological and Chemical Threats’ Behind the Nuclear Curtain Also Require Vigilance

[Financial News] As North Korea advances its nuclear miniaturization and intercontinental ballistic missile (ICBM) capabilities, the senior military leadership of South Korea and the United States has begun fully operating a practical consultative body to address weapons of mass destruction (WMD) in all forms. The meeting comes at a geopolitically significant moment: U.S. President Donald Trump recently warned that North Korea possesses “57” nuclear weapons, while European allies have also intensified pressure on Pyongyang, declaring that they will never recognize it as a nuclear-armed state. The 2026 Korea-U.S. Counter-WMD Committee (CWMDC), held on the 10th, marked a significant milestone by directly addressing the nature of North Korea’s hidden WMD threats, including biological and chemical weapons that could easily be overlooked in the shadow of its nuclear program, amid firm international coordination.■ Trump Mentions ‘57 North Korean Nuclear Weapons’; Korea-U.S. Information-Sharing Arrangement Put Into Operational UseAt the Ministry of National Defense headquarters in Seoul, the Ministry of National Defense and the U.S. Department of War held discussions led by Woo Kyung-seok, director general for policy planning, and Jason Ham, the U.S. deputy assistant secretary for nuclear deterrence and WMD response policy. More than 40 senior security officials from both countries worked together to coordinate the detailed agenda for the 2026 CWMDC. The two sides shared grave concern that North Korea’s WMD capabilities pose an existential threat that is aggravating instability on the Korean Peninsula and across the region, and agreed on specific measures to further enhance their combined response capabilities.
The central focus of the meeting was to establish and verify follow-up measures for bringing last year’s “Information-Sharing Arrangement on North Korean WMD” to an operational level. As various assessments of North Korea’s nuclear arsenal emerge during each U.S. administration’s transition period, President Trump’s recent reference to “57 North Korean nuclear weapons” has created political pressure for South Korean and U.S. intelligence authorities to monitor North Korea’s concealed nuclear-material production infrastructure more closely. European security think tanks have also strongly criticized North Korea’s nuclear alliance policy and declared that they will not accept its status as a nuclear-armed state. Against this backdrop, the meeting was assessed as reinforcing the threadbare but essential combined defense posture needed to close gaps in the allies’ surveillance infrastructure targeting North Korea.■ Responding to the World’s Third-Largest Chemical and Biological Weapons Threat Hidden Behind the Nuclear Curtain Through ‘Adaptive Shield’The hidden issue that deserves attention at this CWMDC is North Korea’s formidable ability to operate chemical and biological weapons, concealed behind its nuclear arsenal. North Korea is currently estimated to possess the world’s third-largest chemical weapons stockpile, after the United States and Russia. It is believed to maintain between at least 2,500 tons and as much as 5,000 tons of chemical agents, including the deadly nerve agent VX and sarin. If these weapons were loaded onto missile and long-range artillery warheads in a contingency, the entire Korean Peninsula could suffer irreversible damage.
This is why the South Korean and U.S. militaries placed cooperation in consequence management at the forefront of the meeting, focusing on responses to variant biological threats such as COVID-19 and on ensuring the alliance’s combined operational environment. The two sides agreed to strengthen their practical capabilities for responding to biological threats through the regular chemical, biological, radiological and nuclear response exercise Adaptive Shield, conducted under scenarios involving a North Korean chemical or biological provocation.
It is particularly encouraging that the Republic of Korea Armed Forces Chemical, Biological and Radiological Defense Command and the U.S. consequence-management unit, the Joint Task Force-Civil Support (JTF-CS), agreed to fully activate personnel and technical exchanges. The move reflects a firm determination to establish institutional infrastructure for removing residual contamination and minimizing damage after a North Korean ballistic-missile strike, while maintaining wartime operational functions. The overwhelming coordination system of the South Korea-U.S. alliance, aimed at completely offsetting North Korea’s asymmetric threats, has begun operating.
