How has North Korea responded to the joint denuclearization pledge by the United States, South Korea, and Japan?

North Korea has firmly rejected the recent joint denuclearization pledge made by the United States, South Korea, and Japan. Instead of complying, North Korea has explicitly stated that it will continue to strengthen its nuclear forces despite international pressure. This response highlights North Korea's unwavering stance on maintaining and enhancing its nuclear capabilities as a strategic priority, directly contradicting diplomatic efforts by these three nations to reduce nuclear armaments in the region.
