A Seoul defense official claims it is possible North Korea has developed a boosted nuclear fission bomb, an intermediate step to developing a hydrogen bomb.
Lee Sang-chul, head of the Ministry of National Defense’s Korea Arms Control Verification Agency, made the claim during an academic conference hosted by the Korea Association of North Korean Studies in Seoul Monday.
Lee speculated that North Korea leader Kim Jong-un’s recent remark that the country is capable of detonating a hydrogen bomb might be propaganda aimed at drumming up public support for the regime’s military-first policy.
However, Lee said that a boosted nuclear fission bomb is already threatening enough, noting its ability to amplify the power of conventional nuclear bombs by up to five times.
Lee also said that the North has readied its nuclear test site in Punggyeri, adding that the North is digging another underground tunnel.
