North Korea pledges further nuclear buildup

Kim Jong-un has vowed “terrible retaliatory attacks” on any aggressor during a key gathering of the ruling party

North Korea will continue to expand its nuclear arsenal, both in size and capability, leader Kim Jong-un has pledged.

Kim outlined the strategy during a weeklong congress of the ruling Workers’ Party of Korea. He declared North Korea’s nuclear-armed status “irreversible and permanent,” and said Pyongyang will continue to bolster its arsenal “as long as nuclear weapons exist on the earth” and as long as the country is threatened by “US imperialists and their followers,” state media reported on Thursday.

“We have a long-term plan to strengthen the national nuclear force on an annual basis in the future and will concentrate on increasing the number of nuclear weapons and expanding the means and space for nuclear operation,” Kim said.

At a military parade on Wednesday held during the party gathering in Pyongyang, Kim warned that North Korea would “deliver terrible retaliatory attacks to any forces” infringing on the country.

Pyongyang portrays its nuclear program, which has made it a target of tough UN sanctions, as a deterrent against US-backed South Korea. For decades since the Korean War, both Koreas viewed each other as illegitimate regimes occupying part of a unified country. Pyongyang shifted its policy in 2024, calling the South an independent hostile state. Language in Seoul’s recently-published strategy documents suggests it is moving to accept the North’s nuclear status.

South Korean intelligence has reportedly found evidence that Kim’s daughter, referred to as “Kim Ju-ae” in international media, is increasingly being groomed as heir apparent. She is allegedly acting as de facto “missile general director,” while General Jang Chang-ha retains his formal position as missile administration commander, the Chosun Ilbo newspaper reported this week, citing senior government sources.

Kim’s daughter, who is believed to be 13 and is never named in North Korean media, is regularly photographed alongside her father during working trips, including missile tests – a practice consistent with how past leaders were introduced to power.

Korea experts say the child is being brought forward early because her gender could hinder her authority despite North Korea’s departure from traditional Confucian patriarchal norms.
