North Korea warns UN: Japan's rearmament could spark nuclear war

North Korea told the United Nations on Monday that Japan's military buildup risks triggering a nuclear war. Its envoy said North Korea's status as a nuclear weapons state is "irreversible" and cannot be negotiated away. The warning came during the UN General Assembly, where the envoy accused Japan of "attempts at rearmament." North Korea called these moves a direct threat to regional security. The statement signals that Pyongyang will not trade its nuclear arsenal for aid or diplomatic deals. Japan has not yet responded to the accusation.
