KCNA reported on the 25th that a spokesperson for the North Korean Ministry of National Defense issued a statement on the 24th, saying that the United States recently attempted to bring serious nuclear instability factors to North Korea's security environment, and North Korea will consider taking countermeasures against US nuclear force demonstrations.

On the 23rd, a US Navy attack nuclear submarine entered the Busan operational base in South Korea under the pretext of crew rotation and replenishment of military supplies.

As early as November 7, the US nuclear-powered aircraft carrier battle group "USS George Washington" entered South Korea. This US action seriously aggravated military tension and instability in the situation on the Korean Peninsula and in the region.

North Korea will vigorously enhance its defense capabilities to safeguard national interests, will consider taking countermeasures against US nuclear force demonstrations, and will choose the method and timing of their implementation based on symmetric and asymmetric principles.
