North Korea warns US of "horrific catastrophe" over nuclear policy

North Korea's Foreign Ministry issued a memorandum sharply criticizing the United States, claiming Washington has abandoned its nuclear disarmament commitments and is effectively encouraging nuclear proliferation. The ministry warned that an expansion of US nuclear forces could lead to a "horrific catastrophe," and that continued "unpunished" actions by Washington could open a "Pandora's box."

Anger over regional cooperation

Pyongyang stated that dangerous consequences could result from the growth of the US nuclear arsenal as well as Washington's cooperation with other countries on nuclear energy and nuclear technology. North Korea expressed particular concern over US support for South Korea, including assistance in developing a nuclear-powered submarine, and the inclusion of nuclear components in the so-called extended deterrence offered to Japan.

In December 2024, Japan and the United States agreed on new extended deterrence guidelines aimed at strengthening bilateral security cooperation in response to growing strategic and nuclear threats in the Asia-Pacific region, as well as reducing the risk of conflict.

Nuclear program to continue

North Korea has repeatedly stressed it has no intention of abandoning its nuclear program. In mid-September, the country rejected a resolution by the International Atomic Energy Agency calling for it to halt nuclear activities. Pyongyang recently also announced a successful test of a new type of weapon, personally observed by the country's leader Kim Jong Un.
